Hello all,

I know I am sorry that I am late with this but I have found a way to make my homemade earthbox cheaper and stronger than before (Six million dollar man theme song here). I have replaced the paint pail with 4" PVC drian pipe (the one with the holes alredy drilles into it. It comes in 10 foot lengths for 5 bucks at the Borg (Home Depot). One pipe makes 18 supports for 4 and a half tubs or 2 tubs with 5 supports see pictures below. Another advantage of using the PVC is that if you have not drilled your overflow hole yet you can change the height of the screen to increase the amout of the water the resovoir will hold by making the PVC pipe supports longer. First remove the paint pails from the screen.

Make sure there are hole at both top and bottom of the PVC to allow air and water to access the area inside the PVC pipe. Also a few holes a different heights will also help with water flow.

These are cut from 10 sections of drain pipe.

Attach the PVC supports to the screen using wire ties just like the paint pails were.

Here I used 5 supports just to see if it would be better. The ceneter support just sits under the screen it it not attached although you can attach it if you want to.

I find your containers VERY interesting. But, the thing I don't understand are the wicks. Can you post a picture of the wicks? I'd like to make some of your containers.


 o
RE: New improved homemade self watering container / Earthbox

The wicking is done by the potting mix itself. The soil sits in the open holes inside the PVC pipe and wicks the water up to the roots. I am currently working on complete instructions for building several types of self watering containers. This design is based on the Earthbox and they work great. See Earthbox.com for more info. I had the instructions posted on here but they were removed because they were over 10 pages back. I am compiling all the info and questions into a complete how to guide. It should be ready very soon.

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

Hi Joe,

I've been following your postings. I read where one of the "box builders" stated that there was soil buildup at the bottom where only water should be, and more "overflow" holes were drilled in the side of the container to prevent overfilling.

I had a thought about using standard non-metallic window screen as a "filter", both in the wick containers and on top of the "soil support" lid, to minimize sediment buildup.

What do you think?

Ron

RE: New improved homemade self watering container / Earthbox

Hello Ron,

This issue has come up before and yes you can use the non metallic window screening or breathable landscape fabric both allow air and water to penetrate them. However if you do not have any large holes or voids between the aeration screen (soil support) and the tub wall it is not needed. The real Earthbox has a small gap between the screen and the wall as well. Some soil may fall into the water reservoir but not enough to worry about it. When you first put the soil into the container it needs to be moist. This moist potting mix tends to cling together and not drop down into the lower chamber. If you want to try please do so and take pictures and let us know how you make out. I have not done this yet and have had no problems. When I dumped my potting mix out of the tubs very little was in the bottom. I empties them to see how the paint pail held up most were fine but some cracked a caved in a little. Bear in mind the soil was soaked from the rain so that may have had something to do with it The PVC drain pipe is much stronger and cheaper than the paint pails so it was an easy decision to make to replace the paint pails with the PVC pipe.

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

Joe,

I haven't made my two yet... I just purchased the containers yesterday. I had already purchased the paint pails from Lowe's last week. Since you mentioned the slight "cave in", I believe I'll just return the paint pails & opt for the drain pipe. The only problem I foresee with the drain pipe is possible seepage of wick soil between the pipe & the bottom of the Rubbermaid container, for there are newer models out... claiming a 20% increase in size... but I'm not sure how flat the bottom of their "new" container is... I'm at work now and can't check it.

I read the earlier "purged" postings, but now can't recall the hole diameter you drilled in the lid (soil support). I imagine if I opt for the fiberglass screen "filter", I could opt to drill a somewhat larger diameter hole... however, for safety's sake, I'll stick with the proven scheme. I ordered some "goodies" from e.burgess.com & plan to plant stawberries, watermelons, shallots, and bell peppers... Please advise about the hole diameter... (trying not to fill up 10 pages again)... Ron

RE: New improved homemade self watering container / Earthbox

Actually the paint pail had lot more half inch holes around the base tnen the Pipe does so it is practically the same thing. The Earthbox uses a support grid to hold up its screen and its wicking chambers do not have a bottom either. It is just a box made from 2 of the support grid pieces that cross each other and the corner of the tub make up the other two walls of the wicking chamber. If it really bothers you hot melt a piece of plastic or something to seal the bottom

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

I made about six of the homemade self watering containers last spring and they've been a total failure for me. I know it must be something I've done wrong. Only change I made was to use mushroom compost instead of potting soil (the mushroom compost worked greated in my Earthbox). I gave one of my boxes to a friend who did use potting soil and his box failed also. Yesterday I plugged my original drain hole and re-drilled the hole about an inch and a half higher to deepen the water reservoir. My friends think they're not getting enough water. The tomatoes in my boxes have barely survived until now and are getting taller but foliage is very limited. Any ideas?

RE: New improved homemade self watering container / Earthbox

Hello Hut123,

Difficult to say without more information I looked at your picture (that is a large fill tube you are using - but should not have any effect on the box). The only thing I can see wrong with the picture is that the containers look like they do not have enough potting mix in them. They should mound in the center to protect the fertilizer stripe from getting wet. Are you using a fertilizer stripe? If so the rain may be getting to it and burning the roots of the plants. Other possible problems are you need to use potting mix not potting soil (you said that your friend used potting soil). Potting mix has no actual soil in it and is what wicks the water to the roots of the plant. Did you change the design of the container? Can the mushroom compost reach down into the water chamber? Mushrooms are like sponges but I have never used it for growing medium. Are you in the South? We had a guy last year that was having problems and it turns out that his boxes were getting too hot. He shaded or covered the side of the box and they took off. I would replant one of the containers with potting mix to see if your mushroom compost is the problem. Check these things out and let us know how you make out. I am using the containers again this year are having no problems. Here are some pictures for you to see.

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

Hi, Joe
Thanks for taking the time to try to help me. And, Im sorry about being late responding but its been hectic here. About the size of the fill pipe I made mine larger because I fill my Earthbox with a water can and frequently the spout slips off the edge of that fill tube and if I try to fill it very quickly the stream of water gushes over the pipe edge. I like the larger fill tube. My problem may be the mushroom compost but that stuff worked fine when I started my Earthbox 4 years ago. I live in Southwest Missouri and not sure if heat is a problem but my Earthbox which is the only thing I have to use for a comparison, and its black is doing great. When preparing the containers for the season I did carefully make sure the paint buckets were packed well with the mushroom compost. I followed your plans pretty carefully, I think. I will try potting mix and see what happens. Maybe Ill also shade one of the containers. Thanks for your help.

hut123,

You should not use SMC alone as a growing medium.

"Spent mushroom compost has been researched as a growing medium additive in nursery container culture for a wide assortment of woody species. Mushroom compost cannot be used alone because of its lack of stability, its low water availability, its high salinity level and its neutral pH. It can, however, be used as part of a total compost component in a mix."

RE: New improved homemade self watering container / Earthbox

what if you used nylon hose, ya know, womans, to put the soil down into them holes. and for the soil not to get down thru them smaller holes, if ya wanted couldn't ya use coffee filter's? that way ya still have your wick and all, am i understanding that right?


 o
RE: New improved homemade self watering container / Earthbox

Hello Joe,
We are having some problems too, maybe you can help? We just made some earthboxes following your single-tub design with the only difference being that we used a pond basket as the one wicking chamber in the center (like your dual-tub), pvc supports in the corners. We put in mostly 60% peat, 30 vermiculite and 10 perlite (with a small amount of compost from some old square foot garden mix). Well, I have been trying to keep the water reservoir filled but it seems that the top of the soil is dry down about 3/4 inch no matter what I do. We watered the plants from the top when they were put in (the past weekend) so they are doing ok for now, but the fertilizer strip has NO moisture. I'm not sure that the moist soil I'm seeing 3/4 inch down is holding moisture from when we first mixed/filled or if it's actually bringing water up from the bottom. We are in the Chicago area and I have trouble believing our boxes are getting too hot at this time of year, BUT we are using black garbage bags as our "mulch." On the other hand, I'm not finding the boxes or mulch hot to the touch.

I can take some pictures of our boxes if it would help. Thanks a bunch.

RE: New improved homemade self watering container / Earthbox

Hello Cecropia7,

I am sorry that have not been able to get back to you sooner I have just been so busy with work and home that I have not much time to be inline. What has been happening with this box? My first guess is the mix. I am sure the Mel's mix will work properly in the Earthbox. Are you using an 18 gallon tub or a larger one? Did you wet the mix well when you filled the pond basket and the tub to start the wicking process? Earthbox filling instructions can be found at the Earthbox web site. The link is below. Please let me know how you make out.

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

Dont anyone get mad at me. I am only asking a question. Isnt PVC used in plumbing? I know things are now PEX tubing but I thought PVC was save for drinking water. If someone is really worried about plastic they wouldnt even be using the plastic tubs. I am a firm believer of using recycled and recyclable products so that may be a good reason to stay away from PVC.


 o
RE: New improved homemade self watering container / Earthbox

Thanks for the reply, Joe.

We have been watering the boxes and the situation is the same. The soil is moist up until the top 1/2" which is dry. What is concerning me is that the fertilizer strip is not getting wet. When we filled the boxes we used moist but not saturated soil in the ratio of 60% peat, 30 vermiculite and 10 perlite, plus a portion (1/4 or 1/3) of each box was some old square foot garden mix we made a while ago (1/3 each peat, vermiculite & compost). When I put the fertilizer strip on the top I did not moisten it. Right now it is dry but there appears to be a little bit of mold growing over the fertilizer strip. I'm afraid to moisten it from the top but maybe I should try it? There are 2 18 gallon boxes and the third box is a little bigger, maybe 22-24 gallon? They are all having the same problem. I think the water is wicking up like it's supposed to, just not up to the top. We are not having the fill the boxes very much until water pours out of the drainage hole.

I'm wondering if putting in a strip of cotton fabric which extends from the bottom of the pond basket to the fertilizer strip would wick the water more efficiently. Or maybe digging the fertilizer into the soil about an inch down where it's staying moist.


 o
RE: New improved homemade self watering container / Earthbox

Thats what I would do. I would dig down an inch or so for the fertilizer strip. it is probably the soil formula that is not wicking as well as it can. What I had someone do once was to water from the top until the water came out of the overflow hole (make sure you fill the water reservoir first) to start the wicking process because he loaded the tub with dry soil. You can try that also. Just add the water on the plant side or the side opposite the fertilizer strip.

Thanks,
Joe

RE: New improved homemade self watering container / Earthbox

RE: New improved homemade self watering container / Earthbox

Just want to say how much I appreciate everyone's helpful posts and inspiring pictures. Joe, your informative how-to posts are particulary appreciated. I'm a novice container gardener who has some experience with more traditional gardens, but am now living in a mountainous area of NW Georgia with steep slopes and poor soil which has necessitated adaptation from what I am familiar with. After reading a good bit about container gardens here and elsewhere, I am starting to see the advantages over traditional gardening on the ground as far as maintenance, water conservation, etc.

I have started this season with Earthboxes which as everyone here has noted, are nice but pricey, but have been reading with great interest the posts and comments about home-made containers. I was intrigued about the plastic bucket grow pots which would save alot of money. I was thinking of trying this design out for beans, okra, peas.

Joe, your design (I have the long pdf version) calls for a single 5 gal pot or two 5 gal pots - one inside the other. I was wondering if you or anyone else here had tried a variation using a 3.5 gal pot inside a 5 gal pot which would seem to allow more volume for water but at the expense of potting mix volume. Do you forsee any problems with this ratio of potting mix to water? Can you employ the EB method of dry fertilizer on the surface using a pot like this? How do you apply fertilizer - around the edge? Any overheating problems or fertilzer distribution concerns? Do you have any other additional tips or precautions to share about using buckets like this.

Thanks for any advice.

If you look on the bottom of those Rubbermaid Roughneck tubs you will see that they are made out of Polypropylene. While I don't think any scientist would say that Polypropylene is completely safe (it IS a plastic afterall) - it is FAR and ABOVE safer than Polyvinyl Chloride (aka PVC). Instead of using PVC for support in these self-watering containers you should try to use a Polypropylene alternative (they are out there is some Home Depot's in the piping section - look for a recyclable symbol of 5). You KNOW PVC isn't safe when companies such as Walmart and IKEA begin to phase out products that use PVC (due to consumer complaints). And yes - unfortunately, PVC is used in both water piping and in some home sidings. But the danger from PVC comes when it is HEATED (such as sitting in the sun all day) when it releases all its endocrine hampering fumes into the soil and plants near it.

RE: New improved homemade self watering container / Earthbox

nice. similar to the homemade EBs i'm running with, except i went a bit simpler (read: faster).

i drilled a buncha holes all over the inside bin, not just at the bottom, for good aeration. and instead of using a big tube for filling, i just drilled a few more overflow holes and use those to fill with a small hose that fits in and a homemade funnel made of a cut-up water bottle.

thing is, in hot weather my tomatoes are still pretty heavy drinkers and i need to refill every few days. but i just figured out an easy way to do it.

i have another container that i used for lettuce. it's a 40-quart plastic bin, short, wide and long. i set it up by my self-watering bins and run a hose like my filling hose into the reservoirs of my containers, making sure the hose lays at the bottom of the reservoirs.

then i fill the hose with water and shove it into the bottom of the old lettuce container which is filled to the same level as the EB overflow holes and voila, by the magical effect of the siphon i've effectively tripled the reservoir size. now i can just dump in a bucket of water into the extra bin every week or so.


 o
RE: New improved homemade self watering container / Earthbox

Thanks Joe for your designs. I've made about 10 of them to do my vegetable garden this year.

My water system is:

1 50gallon Rubbermaid Heavy Duty trash can. Drilled a small hole in the bottom and attached a 1/4" drip line which goes to a 5 gallon plastic bucket with a float value set to about 2". The the plastic bucket has another 1/4" drip tube that is connected to the 10 homemade "Earthboxes". So the siphon action keeps them fill to 2" of water. Everything is on a flat deck. So now I only need to fill up the 50gallon can every 2 weeks or so and can go on vacation and not worry.
Can post pictures if anyone interested.

Regards and thanks for all the info on this site,
EM

P.S. Learned the hard way to use the peat moss + vermiculite mix + compost mix. I used some "high quality" planting mix initially. All the plants did fine at first, but then died from being waterlogged.

Joe,I'm not in a hurry for a response as I'm in Michigan and won't plant till June 08.I have a few questions.I'm converting some decorative 5 gallon planters to earthboxes ,where I previously grew green peppers in regular ammended soil.One question is instead of regular fertilizer can I use a compost tea or some other more organic means of fertilizing? Also I hear alot about colored plastic mulches so could I use a green plastic on top and can you reuse the potting mix from year to year? Now after reading some comments about the saftey of pvc I wonder about the saftey of my plastic pots for growing food(I origanily started growing in pots because my yard is landscaped with r.r ties where the previous owners had a garden).I'm only going to start with converting 2 this next year as I plant about 30 pots. .thanks for your time

RE: New improved homemade self watering container / Earthbox

Hi Linda,

Not Joe but I grow almost exclusively in EarthBox brand EarthBoxes. You can use compost tea. You would mix a weak solution of the compost tea and pour it into your reservoir. I call it "bottom feeding". 2007 was my first year with EB gardening and after the major growing season was almost over I began to experiment with pouring weak liquid fert solution into the EB reservoir - worked great!! You can use colored plastic mulches instead of black plastic. What ever you decide to use just be sure it is not toxic to use around food plants. Yes PVC does have some issues but for info on that you will have to do heavy duty web research and after reading you will have to decide which path to take. I have 15 'real' EBs and 5 "growboxes" that I made myself from 5 gallon buckets for the reservoir and 3 gallon buckets for the growing chamber. I used PVC pipe for the watering tube in 2007 but will use Bamboo in 2008. I plan to use red plastic on 2 of my tomato EBs in 2008 just to see if there is a difference in yield. I have been told that in my zone (7++) there is no advantage to using the red plastic.

Good luck in 2008 - you are gonna LOVE gardening in EarthBoxes. Come join us over on the EB forum. In respect for the EarthBox company most of the members on the EB forum do not talk much about their alternative containers. It is a really lively forum most of the time with LOTS of info on alternative ways to grow in EarthBoxes.

You write about earth boxes & their clones.
If you look closely at the screen in the real earth box, or watch the video, you see there is a hole in the screen that is in the corner. This is packed with potting mix to serve as a wick. I'm debating whether to build one or buy one. The shipping charges are high.

RE: New improved homemade self watering container / Earthbox

Is there any simple instructions on making an earthbox? Anyway, I have been lurking in this forum and I don't live in the USA. What some people do here is this : they get a plastic containet; they fill the bottom sides with hard pebbles; then they put the potting mix. They also put something like a long bamboo or PVC pipe LIKE THAT... is the "idea" the same as the earthbox?


 o
RE: New improved homemade self watering container / Earthbox

its_kristy,

To get the core out of the bamboo I use a long drill bit called a paddle bit. You will have to find one with a long stem or drill each bamboo rod from each end to meet in the middle. If the bamboo is really old and dry you can just shove a metal rod down thru the middle and that will push out the dried inside 'stuff' - this did not work to well for me so I got the paddle bit.

drtluvr_in_z6,

Can't tell where you are in the US but if you are on the east coast the shipping charges are not that high for EB. They have a special 'clearance' price on EBs with NO casters. You get 5 EB for $125 and the shipping is $25 for the whole lot. If you go on the website click on the 'clearance' tab. Right now the clearance boxes are available in white and terracotta. You do have to buy the entire 5 to get that price.

RE: New improved homemade self watering container / Earthbox

Below is a copy my response to to a post emgardener made on showing photos of his automated watering system for earthboxes on another thread. I think it's a good way to cheaply water a bunch of boxes and wondered if anyone had thoughts on how to improve it.

[snip]

Nice post emgardener. I've been looking around for a cheap automatic watering system, yours makes a lot of sense.

What do you think of this idea -

Why not put the Hudson valve in the 5 gal bucket and then you could get rid of the reservoir? If you mount it high enough on the side, you should always have enough water to keep the feeder/outlet tube under water (and preserve the siphon effect to the rest of the containers.) Or am I missing something?

I'm going to try it on the 30 homemade boxes I've got on my garage roof. My pics are here.

RE: New improved homemade self watering container / Earthbox

I am way too cheap, errr, FRUGLE to actually buy an EB but I have read a lot about them. One of the things I have read is that "they" get really testy about us common folks using the name EarthBox(R) to discuss anything except their company's product. In light of that I propose that we start calling our homemade versions something else-I call mine Soil-Cells!

This year I am experimenting with a Soil-Cell design that I can build for $1.50 each.

So far this is the cheapest & fastest way I have found to make Self-Watering-Containers. And, yes I will be hooking mine up to an automatic watering system this summer.

RE: New improved homemade self watering container / Earthbox

I find that the best way to feed plants is to foliar spray them weekly. I mix weak compost tea, seaweed tea,and any other organic nutrients that I want to give my plant into a spray bottle and spritz the leaves in the early morning before the sun gets hot. This works much better than feeding thru the roots, and causes no problems with the water in the reservoirs getting mucky.

PVC Issues

PVC is normally rigid. To make PVC flexible, plasticizers are added. Some plasticizers are not toxins or carcinogens in a classic sense, but they mimic steroid hormones and may effect the way your cells read the genetic code (example: feminization of males). I bring up this issue in a thread about using vinyl coated window screen as a material to make pots. I bring up a similar issue, involving using fabric made from recycled PET soda bottles, in another thread about using bags as pots (Wal-Mart has cheap bags, made of recycled PET, that I think could be used as pots).

PVC pipe is somewhat rigid. Therefore, I assume that these "dangerous" plasticizers are not added to PVC pipe. I agree, the concern seems "odd" given that drinking water comes through PVC pipe in many homes.

It is just an example of how stories mutate upon retelling. "Some PVC products may be dangerous" mutates to "All PVC products are dangerous".

I now see that there is a thread in this forum specifically about PVC pipe; this thread in turn links to a more detailed thread about PVC pipe in the tomato forum. Link below.

Upon reading the thread in the tomato forum, I realize that my concern about fabric made from recycled PET was based on reports about polycarbonate bottles. I was confusing PET with polycarbonate. OOPS! Sorry.

Upon reading the other thread, I now realize that part of the PVC concern isn't just about plasticizers; but about issues related to the manufacture of PVC and the disposal-by-burning of waste PVC (or accidental fire of non-waste PVC). In regards to PVC pipe, these other issues have some merit. In my opinion, these other issues do not have enough merit to reject using PVC pipe as a structural component in home made earthboxes. Most of the other issues (except accidental fire) probably have simple technological fixes and just require enforcement of rules and laws already on the books.

RE: New improved homemade self watering container / Earthbox

about 2 years a go I found plans for making EB type containers, they used 2 rubbermaid totes, a 14 gal inside an 18 gal. I haven't been able to find the plans again on the web. Does anyone have copies of these plans.
thanks

RE: New improved homemade self watering container / Earthbox

jmalt, we made our own version of these growing containers last year. They worked great but due to expense hubby substituted a red plastic coffee cannister( commonly sold in most groceries now). He drilled plenty of holes in the cannister and used it as the main wick. Works just fine and saves money too as well as recycling the coffee containers.

RE: New improved homemade self watering container / Earthbox

I made several boxes by combining some of Joe's ideas. They have 2 wicking chambers, no holes in the screen, and 1-4" aeration tube. I used Miracle Grow Organic potting mix and white plastic on the top so it wouldn't get too hot. I put 2 cups of lime in the tomato box.

I planted them just over a week ago, and so far most all of the plants are starting to turn yellow. The top of the soil has stayed wet since it rained 6 days ago.



The pepper in the bucket is from the same tray as the 2 in the back of the self watering container that are now smaller and more yellow . I've read on this board that you don't have to use the plastic cover, so I'm thinking maybe I should take it off, take out the fertilizer strip, and hopefully allow the soil to dry out a little more so the plants won't turn yellow. I'm wondering if I should've used a different soil. Anyone having better luck that could advise me?

RE: New improved homemade self watering container / Earthbox

I just built my first box. I followed the instructions found on www.josho.com. Here where I live, there is a "second hand" materials store where I bought a 25 foot of extruded aluminium pipe (less that 1/8" thick) for $5.00 dlls. After I cut the pieces I need, I'll be paying less than a dollar per tube. For my first box, I went all out and bought a copper pipe for $5.00 at Lowe's. So far, the birds ate all the cantaloupe plants but one and it is doing ok. I haven't noticed it growing any faster than the cantaloupes growing on regular soil, but it is not growing any less either. I went on vacation for a week and it was great not having to worry about watering. If this works, I'll be building more of them next year.

RE: New improved homemade self watering container / Earthbox

To the poster above with the pictures....if you have no holes in the "screen" your plants are probably too wet.


 o
RE: New improved homemade self watering container / Earthbox

I am confused about where to put the landscape material. Does it go over the aeration screen? Do I cut a hole in the landscape material so that the soil is able to wick the water up to the roots? I just assumed that it would go over the screen to keep the soil from falling down in to the lower water reservoir. I see that in some of the pictures, the landscape material is covering the tubes for aeration. I would appreciate any help on this.


 o
RE: New improved homemade self watering container / Earthbox

yes to both your questions. I put window screen over my aeration bench, and cut holes over the wicking chambers.

RE: New improved homemade self watering container / Earthbox

One more question about the landscape material: Do I need to put this around the 4" PVC supports that is used for wicking? If not, does the soil get in to the water reservoir?


 o
RE: New improved homemade self watering container / Earthbox

No the supports do not get covered. Yes a little of the potting mix gets into the water reservoir but not enough to worry about it. These things work, I and many here have been using them successfully for 5 years (at least for me) or more. I have not had any problems with them.

RE: New improved homemade self watering container / Earthbox

RE: New improved homemade self watering container / Earthbox

Hello, this sounds like a great idea. I have a few questions about it though. First off, what is an earthbox?
Second, could you use this homemade self-watering container
for container gardening? If so, how? Would I have to make changes and measurements to your design based upon how big the container I use would be?

So far, I know the most common size containers I would use for container gardening would be 1 gallon, 5 gallon, and 10 gallons; possibly 15 gallon containers, but that's not likely unless I plant something that needs lots of space, like melons, tomatoes,
eggplant, or any type of squash.

RE: New improved homemade self watering container / Earthbox

Anyone from Arizona use these Earthboxes?

Just wondering since the heat can ruin plants so fast! How often you have to water, etc.

Share your experience?


 o
RE: New improved homemade self watering container / Earthbox

The heat can be an issue in your area. We had a guy from Texas if I remember correctly and he had a problem with the tomatoes wilting until he planted another container next to the first one. The second one shaded the side of the first container the the roots we not being roasted. the first container did fine from that point on. I believe that tied a few boards to any side that was in full sun. the plants were about 3 inches from the side of the container. perhaps moving them closer to the center may help as well. I have also head of people mounding dirt around the boxes as well or partially burying them with a chamber for the overflow hole.


 o
RE: New improved homemade self watering container / Earthbox

I read about a simple solution to the PVC pipe problem in Organic Gardening.You simply use a tube of cardboard like one that comes in the plastic wrap or aluminum wrap and shove it into the soil.Then you pour pea gravel down the tube and slowly remove it.I guess you could leave the paper tube in since it is biodegradable.

RE: New improved homemade self watering container / Earthbox

azbookworm, and others in hot climates,

I am in southern AZ and just built my first self-watering container the other night.

While I can't answer you on the basis of experience, I was in Lowes the other day and ran across some stuff that may work really well for insulating. It looks like a roll of foil bubble wrap. It was near the plumbing parts. I didn't catch what it was exactly. I believe it's made for insulating AC ducts, but it looked like it was about the right height for wrapping the Rubbermaid containers. Just sort of popped into my mind after reading your question.

Hope this is helpful.

RE: New improved homemade self watering container / Earthbox

This is my first year with earthtainers and was also wondering about the rubbermaid totes getting to hot. I'm going to try and use the leftover lids for shading the boxes. Any ideas on how to attach the lids to the sides of boxes leaving a 1 or 2 inch air space between the lids and the side of the tainers? This idea won't probably be pretty but it should work. Shouldn't it???


 o
RE: New improved homemade self watering container / Earthbox

sorry if this has already been addressed, but are there alternatives to using pvc tubing? not because of the pvc concerns mentioned up-thread, but simply because i don't have the tools to cut it! any thoughts on this?

also, are the fertilizer strip and mulch necessary? i was planning to build a SWC for root vegetables, which would mean that I'd have quite a number of plants per container, and, if I understand all of this correctly, would therefore have to cut a corresponding number of holes in the covering? I'd just as soon leave the top open and use slow-release and/or fertilizer in the water; am I missing something here?

Thanks!


 o
RE: New improved homemade self watering container / Earthbox

Hello Mollywk,

If you have a drill then just drill 2 or 3 1/4 holes to the bottom of the tube. It does not need to be cut. Also I have included a link below to see what can be grown in a SWC. Yes you can use fert in the water it has been done before. The reason for the cover is to protect the fert strip from getting wet and releasing too much fert into the soil at once and burning the roots and also, to keep the soil from drying out due to evaporation.

Thanks,
Joe

shading the tubs

Vmckague,

You can use some scrap wood or branches as spacers and then just tie a string around the tub. It will not look pretty but as you say it should work. A better solution is to use 1 inch foam insulation sheets sold at the home centers they are not that expensive. Foam coolers may also work if you cut them and tie or glue them on.


 o
RE: New improved homemade self watering container / Earthbox

I just built a test box and use the Earth-Gro potting soil ($5 per 2 cuft at Home Depot) and leave it outside under the sun and wind. It still stays pretty moist, not wet.

One problem I have is with cutting the lid, with a knife, it's still quite challenging and time-consuming.


 o
RE: New improved homemade self watering container / Earthbox

The dual tub design is the easiest type to build. It does have the cost of the extra tub (one 18 gallon tub and a 14gallon tub to fit inside it). See my instruction from the link above and here below. No need to cut the a lid with this design.

RE: New improved homemade self watering container / Earthbox

Well tools are like anything else you get what you pay for. so buy the best tools you can afford and go from there. you need to have a drill and a drill bit set. Sorry about the long URls we can no longer use short URLs on this forum anymore.

This would work nice:

a 12 inch metal ruler
a good utility knife

found this one to works the best:

If you are really cheap for tools, find stuff at yard sales. Just be careful with battery / cordless tools this way, often the batteries are toast, and cost a LOT to replace.

RE: New improved homemade self watering container / Earthbox

Thanks for bumping.

I am building the 18 gallon tote SWC. What is the middle smaller pipe for in the very first picture, filling ? I am thinking about putting the filler tube inside one of the corner 4" pvc support.

Originally, I was going to put the 14 gallon tote inside the 18 gallon tote. This allows about 6 inches of space for aeration and water, which is plenty, even too much if you ask me. It seems 14 gallon is plenty of space for the mix. But I am thinking 4" is plenty for the aeration and water rather than 6". I don't mind filling every other day. It's only 5 containers and eventually probably set up automatic watering.

Anyways, so there I was at lowes getting ready to buy the rubbermaid 14 gallon tote. Then I see the sale price for 18 gallon at $6 and 14 gallon at $7.47. Sheesh, paying more for less material. http://www.lowes.com/lowes/lkn?action=productList&N=4294961544&Ne=4294967294&Ntk=i_products&Ntt=rubbermaid+gallon

So I decide I am just going to put one 18 gallon into another. I will use 5 piece of 4" X 4" support to allow more space for water but at the same time give almost 18 gallon of potting mix. There will be small gap the 18 now won't sit snug on top of the other one.

Comments welcome.

RE: New improved homemade self watering container / Earthbox

I am posting a follow up to let you know that I made 2 boxes and the plants are doing amazingly well. I don't know how to add pictures to this post but take my word for it, the plants are spectacular. I am growing some Jolokia peppers and from all that I have read, they are suppose to be very hard to raise. Well, you wouldn't know it from the way these are growing. The amount of peppers that it is producing is incredible. For me, there is no other way to garden.

Joe's plans

I followed Joe's plan for last two years. I think mounding the soil mix is crucial so the mix does not get too wet during rain. I use landscape fabric in the wicking chamber and it work well. I put two tomatoes in an 18 gal roughneck and also put five peppers in that size. I put one tomato in a five gallon Home D bucket, one inside another. I make the wicking chamber a little higher now so there is more water in the bottom bucket and it also allows for air to surround the soil bucket which now does not sit all the way into the resevoir bucket. I wedge some scrap wood between the two buckets to allow air to surround the soil bucket. This works so well all of my engineering effort is figuring out how to support 12' tall tomato and 6' tall pepper plants.


 o
RE: New improved homemade self watering container / Earthbox

There is no need to be concerned about using PVC, or drilling out bamboo, etc. Simply eliminate it altogether! Rather than drilling a 1/4" overflow hole in the reservoir container, drill a 1" hole instead and use it for filling until water runs out. You can even stick your finger in the hole to check for water remaining in your reservoir if you like.

RE: New improved homemade self watering container / Earthbox

Thanks to all of you who shared your designs and experience with self watering containers. My husband is building some for me to plant veggies in as I am typing this. We have 2 wheeled ice chests we want to recycle, and since they already have the wheels, we want to make them into self watering containers. Does that sound like it would work ok, or can you think of a reason why we should not. We are also making 4 self watering containers out of 14 gal. totes. Is that too small for 2 indeterminate cherry tomato plants? I was thinking maybe only one tomato should be planted per container. I have already viewed the recommended Earthbox diagrams, but it has one plant being planted in one corner. Wouldn't it be better to plant one plant in the center? I will be using a 5-6-6 organic fertilizer. Sorry for the multiple questions but I am new to this. Thanks in advance for your help and advice.


 o
RE: New improved homemade self watering container / Earthbox

This is my first year with a self watering system and I used PVC for the fill pipe and some PVC lattice we had laying around to support the soil before I realized that that was probably not a good idea. So I am interested in making a switch to bamboo because my systems work and I don't want to mess with the design, just incorporate friendlier materials. Can those who used bamboo as a fill pipe please tell me about your experiences? Forgive me if I did not find a thread on this already. I did try searching but am new to the forums so may have some operator error going on there. My concern is that the bottom of the bamboo will be sitting in water and the majority of the rest of the pipe will be in moist soil. Has anyone had rotting issues? Is there a preferred bamboo type for use in this situation? How much of a lifespan do these bamboo fill pipes have (copper may be more $ up front but less in the long run)?

Thank you for any help,
Chrissy
