CNS 17 for fertilizer

ykerzner(9 TX)December 7, 2010

Keeping in mind the 3-1-2 ratio, would this product work as a substitute for Foliage Pro? It has a ratio of 3-1-2, so would I need to apply it at three times the rate of FP to get the same results?

I remember commenting about the cns17 back in Oct on a thread posted by 'epicseedman'. Here's what I said. Keep in mind the question he asked might have been subtly different from yours, but the answer is probably in what I said:

"FWIW - I went to look at the CNS product line.

All coir and CHC products are VERY high in K, so it would seem that if the CNS17 product was really developing a product specifically for use with those products, they would have lightened up on or eliminated the K content. As I reviewed the label, I honestly didn't see anything at all that would set this product apart as being any better than other 3:1:2 ratio products when using coir or CHCs. It does lack many of the minors, and you need to use 3X as much of the 3-1-2 as 9-3-6 - 8X as much 3-1-2 as 24-8-16 to get the same bang. I actually think MG 24-8-16 or 12-4-8 would be better choices."

Of course, I think that FP 9-3-6 would be a still better choice.

I plan to use CNS17 only during the winter when temperatures are below 70 F, and also because it seems no stores in the area carry FP 9-3-6. Micronutrients are supplied by a different fertilizer. Is it worth paying up to 50 dollars for one gallon of FP by buying it online?

For me, it would be worth the price to pay for peace of mind and very healthy plants..

I paid 56 dollars for mine and drove 35 miles to get it.:-)

For one gallon, I presume? How long did it last?

I have an 8-ounce bottle of Foliage Pro that I received last Christmas, and I haven't finished it.
I'm going for the 32-ounce bottle next, which costs $20 at a local specialty nursery.

Josh: Do you use Al's recommendation of one tspn/gallon when watering?

Yes 56 dollars before tax a gallon...If I did not share it, it would last me for months and months if not over a year or longer..

I use 1/2 tsp/gallon all summer and 1/4 tsp/gallon all winter..

Hey, Mike! ;)

Ykerzner, I do use a tspn per gallon on the "hungry" plants....citrus, maples, osages, conifers....
Al has helped me quite a bit. One of my main foibles has been under-feeding plants in these bark and
grit-based mixes. I'm learning, though ;)

Some plants I fertilize more often, like Mike, and so I use about a half tspn.

I'm using a quarter tspn on my indoor peppers this time of year for maintenance.

I give my outdoor trees a splash from time to time, but the rain keeps them flushed.

While plants are growing well, I use a tablespoon (9-3-6)overflowed by about a teaspoon, so about 4 teaspoons in 2-1/2 gallons of water, weekly. Of course, you'd have to reduce the amount for plants in heavy soils. In winter, under lights, I fertilize at every watering with a fertigation solution of 12 drops of FP/gallon of water, which is a little on the light side, but should be about right for plants in fast soils but not under lights.
