Yazan,
Echinacea respond very well to wintersowing. If you plant the seeds into any container with drainage holes and decent quality growing medium, then cover with a clear plastic cover (seran wrap), you can put the container right outside and let the seeds sprout naturally as they would have if they had fallen on the ground. You also need to poke a few holes in the cover to allow for air exchange and for the rain and snow to provide moisture. Once they sprout, you can remove the cover. Echinacea should be able to tolerate most weather that comes its way. Or you could throw a cover over the seedlings when frost threatens. Check out the wintersowing FAQ. Good luck. Echinacea are great plants, and they will multiply for you so you'll never be without them.

If your cover has them, use them. Most covers don't. Just watch to make sure they don't evaporate too much of your humidity inside the try. If there is no condensation inside the lid close them down at least part way.

Hopefully you aren't using actual dirt (soil) but bought some soil-less potting mix for starting seeds instead? If so which brand of mix are you using?
Soil compacts far too much and drains poorly to use for seed starting.

".... difficult and slow to start Vitis Riparia plants from seed"
Noxious weed is some areas, prohibited in Ohio. May be injurious to nearby trees and shrubs if not controlled.
It doesn't sound like scarifying would be especially helpful, or soaking either. They do need to be stratified, the chill must be moist to be helpful, dry storage in the refrigerator is only storage - the key is the moisture.
Plants for a future database: "Seed - best sown in a cold frame as soon as it is ripe. Six weeks cold stratification improves the germination rate, and so stored seed is best sown in a cold frame as soon as it is obtained. Germination should take place in the first spring, but sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant out in early summer."

1) nothing
2) that will be difficult as it is late to order seeds so they are all swamped and running behind. Depends on the varieties you want. Local stores will be the fastest source.
3) no thermometer is required for any reason> See the How do I get started FAQ here Heat may is automatic and both dome and heat mat are removed just as soon as several of the seeds break the soil surface.
4) as soon as any break the soil surface, yes. So many just turn the lights on from the beginning.
5) another light? probably which is why the 4' lights are recommended. there are several current discussions here on lights - pics and all - as well as 2 FAQs on lights. How much room will it take? No way to know that. Depends on the number of plants and what you transplant them into.
Hardening off is not normally done with just germinated seedlings. That's an easy way to kill them quickly. Hardening off begins a week to 10 days before transplanting to the garden.
Please do check out all the FAQs here as they do cover all the basic questions and then some. These same questions come up weekly here so there are many advantages to having the FAQs so available.

Digdirt, hit it. Plants vary.
I don't consider it "stunting". Plants will wait until the right temperature/light cycle to take off, as long as they are not damaged.
Or just search "cosmos cold tolerance" (example) for each of your plants. One site says cosmos will tolerate 35 degrees.
The link below doesn't really pertain, but you can find similar that might. A lot of studies have been produced on the matter.

Most plants are surprisingly hardy at the early stages as long as they are not left too cold for extended amounts of time. If you are worried about the temperature and already planted just cover the little guys with a sheet or some good plastic overnight. The weather should be warming up pretty fast, and if not just blame that darn groundhog!

No it's not.
googleimages has lots of seedling pics for this particular plant that you can compare yours to.

Agree that unfortunately most store-bought produce are hybrids so seeds from them will not breed true and in some cases are sterile and will not breed at all. If it grows it will not produce the same type of melon but will revert back to one of its parents or some crossed variety that may or may not be edible.
If you know the name of the variety you can determine if it is a hybrid or not but there are very few non-hybrid melons.
It is up to you. If you want to try and see what happens and have the time and garden space, fine. Otherwise, if you really want melons you need to buy seeds.

I tried plantin from Landreth below Hollyhock (Indian Spring variety), Foxglover (digitalis), Butterfly weed, Bee Balm. Black Eyed susans
From Burpee I tried agastache and Bee Balm (2 sources), and Lavender.
None of these say plant directly in Ground since some do not transplant well at all. So I avoided these. I kept them waered well (moist), and the hollyhock is only one that came up, but then shriveled and died. I plan to try this again soon. Ill use the styrofoam approach with a cover and new potting soil from Miracle grow this time.
Thanks for everyone kind guidance here. I really appreicate everyones input. I teavel nearly 100% in my job making it hard (due to sheer exhaustion) to get on here to see who posted any feedback. i love this forum

I haven't seen it but have read of it, with some down time this evening I browsed a little for albinism in artichoke and it may not be all that uncommon in a given percentage from any lot of seed.
Several online mentions, and from Territorial Seed who I know to be reliable source of information- in their artichoke from seed description:
" Sow heavily and expect 70% germination. Of these seedlings, about 20% will not produce high quality plants. Cull out the small and albino plants."

Hi Melissa67 - Desert (sp.) Rose is not a true rose (ie Rosa species) but an Adenium. There is a specialist Adenium Forum here on GW and I am sure someone over there will be able to help you further.

Young plants do not need fertilizer. Fertilizing seedlings will often set the back. I would say the ones in with your wifes plants probably have the right amount of moisture to grow better. Those fiber pots are useless. They dry out and mold. I tend to sprout seeds in a shallow communal pot and transplant into disposable drinking cups when they are ready. My favorite communal pot is mushroom flats with holes in the bottom.
Your lights should be an no more than an inch above your plants for optimal light exposure. The plants should not touch the bulbs though. Either lower your lights or raise your pots by putting something under them

Linked a bunch of potting-up discussions you might want to read through for more details.
When? Whenever you are comfortable handling them. There is no set time and you do not have to wait for true leaves they are just a bit easier to work with them. Handle only by the leaves, not the stem. If multiple plants together they need to be separated before the roots get all entangled. Do not leave more than 1 pant in a container.
If going to 16 oz solo cups then don't fill the cup. Too much soil for a young seedling. Instead fill it 1/2 full and transplant. Then as the plant grows you can add more soil around the stems. If using 9 oz cups go 3/4 full. If the plants are very leggy you can transplant deeply to just below the bottom set of leaves and bury all exposed stem. If they are not leggy then just plant them at the same depth they were.
No need to remove the soil. Some will fall off anyway, if not don't worry about it. Water before transplanting.

Do you have a space in your flower beds on the south side, near the house to set up a cold frame? I used this to start flowers for years before I got my lights and greenhouse.
Near the house because it is warmer and on the south side because it is the sunniest. A simple cold frame costs only a pittance. You need 2 poles or something as long as your cold frame that you can staple plastic to. Next you need some heavy guage clear plastic and something to use for hoops. Heavy guage wire or dry cleaners hangers unwound and bent in a hoop shape. Look around and see what you can find--they only have to sit 2 to 2 1/2 feet high. You also need a couple of stones or bricks.
Cut a piece of plastic --doubled is best--wide enough to go over the frame with room to staple your poles on each side. Then gather together the ends and stretch it out past the last hoop. Put a brick or stone on this to hold it.To open it a little bring the end on the least windy side upto the first hoop and use a clothespin or clip to hold it there. On days you want it open more you can roll it up on the front pole. You will find you have to open it a little or a lot every day even couldy days. In a small space like that it doesn't take much for it to get too hot from just the sun. I opened mine around 9AM in the morning and closed it around 4 PM to let some heat build up
Set it up a week or 2 early to warm the ground. I suggest you plant your seed right in the soil. They take less care that way and do better than planted in pots. Make sure your plants don't touch the plastic or they'll freeze. The cold frame will protect your plants from a couple of degrees of frost. If you know it's getting colder than that throw a blanket or something over it
When transplanting these dig them out getting as much root as possible. Have your hole ready and fill it with water and let it soak into the ground, then plant your plant. Place an upside down colored--not clear pot over the newly planted plant. Place a clump of dirt or stone on top to keep it from blowing away. Leave it for 2 or 3 days. This allows the roots to get moisture right away and shades the plant so it can spread it's roots without coping with a too hot sun. When you take off the pot you'll notice a ring of moisture right around the plant and your plant is standing up and not wilting.
You can also use milk jugs or large pop bottles with the bottom cut out Warm the soil where you want them to grow like above. Plant 2 or 3 seeds and press the bottle into the soil over the seeds. Remove the lid to allow excess heat to escape. Check for water every couple of days and wait for them to grow. Again don't let the plant touch the sides. These are like little clouches and work great.
So there you have it. Hope it works for you
You have plenty of time if you still want to try the wintersowing method. Technically it's spring sowing from equinox onwards. I keep sowing right through the first week of May, sowing tender annuals last. Come on over to the forum, we're friendly. Several people offer seeds for SASBE to wintersowing newbies. Please look at the forum FAQs first. There's a ton of information there, thanks to Trudi. There is a section specifically on spring sowing if you scroll down.
