Jack's Professional Fertilizer
I've been thinking about this for a while and it has recently come up so I thought I'd start a new thread.
There are a number of expensive hydroponic fertilizers on the market and while the old "you get what you pay for" often holds true, this might not be one of those times.
See, plant nutrition has been around for a long time prior to people growing weed indoors. Companies that have been producing well known fertilizers have also been around for a long time. They have spent many years doing R&D and they also have the money to do more of it than the smaller boutique type companies.
One of the most respected brands long used in large scale nurseries is "Peters" made by J.R. Peters. I promise you from experience that even their all purpose 20-20-20 works exceptionally well. In fact, probably better than the Ionic I have been using.
Anyway, it seems they have a whole line of professional fertilizers including one specifically made for hydroponics. Below is a list of their products.
I for one will be switching to this brand - now to figure out the perfect N-P-K levels.

Excellent information.
I have been using Jack's Classic ferts for many years now. I am extremely happy with the results I obtain. My plants and I love this stuff!
I was unaware of this line of Jack's Professional products.
Very impressive lineup.
Rick do you know if the Professional series is available in less than 25lb size?

Yes, it seems that you can only get it in 25 lb bags and.. wow.. over 60 different products.. all of them fertilizers.. that's more than Advanced Nutrients line.. I bet it's even more then Grotek.. and they make Cotton food.. lol
If you get the triple 20 then be careful.
From the link above:
The general-purpose industry standard, 20-20-20 is great for maintaining plants in garden center and growing facilities. It provides fast green-up and great foliar expansion due to the high percentage of ammonium and urea nitrogen plus balanced phosphorus and potassium for excellent root and shoot growth.
That also means it can burn easily.
One of the most popular formulations, 20-10-20 GP has the traditional micronutrient levels needed for general production including propagation and all types of bedding plants. High nitrate nitrogen levels (60% of the total) provides for green foliage and more compact growth.
Where as I think this will not burn your plants so readily.

5-12-26 Hydroponic
Product # 77251
THE fertilizer to use for hydroponic plant production. It is easily modified to fit specific crop needs and individual water qualities. Supplies magnesium and sulfur with 100% nitrate nitrogen.
Looks like this place carries it. http://www.waldoinc.com/index.htm
I'm going to buy this Monday if I get time. Perhaps I will sell a few 1lb bags on Craig's List.

This thread really interests me because I totally agree with what you say about professional "legitimate" growers. They too want the brightest flowers, biggest buds and tastest fruit.Originally Posted by RickWhite
So, how has your grow been going using Jacks?
Cheers, YGB
I just started using the Peters Professional Hydro (5-11-26)
For fans of fatman7574, you should know that the n-p-k ratio produced by adding Calcium Nitrate to the Peters is close to 3-1-4.

on the pro website is a link to thier lab site (where you can have your water and soil tested, and they will specialy formulate a nute just for you based on the test) on that site is a link called library and there is a pdf about 3 things to know to prevent fert problems, it is full of great info
I just emailed them a few days ago asking if I could get a sample of thier K-Trate as I am looking for a 2-1-3 for flowering
will let you know if I hear from em???
good tip on the library.
the article about water quality should be read by everyone.
