thats a good question. I was looking at a can of
great white right now.
Great White CFU's/CC of each species is 269,786
My pack: 5 bilion spores/gram.
Great white: 99.9% inert ingredients
My pack: 70% inert ingredients....
My guess is you could use a lot less and be fine in hydro. This product is sold to big ag, and all application rates are originally for soil. Given that I was told by the manufacturer that it is very hard to over due it:
"Noted your info, all our microbials are ecofriendly, overdosing will not cause any problem.
For Powdery mildew, you may use Pseudomonas fluorescens, however you have to use Ampelomyces quisqualis to eradicate in various stages."
I figured the dosage was fine. You can always cut back and observe results. Even if you ran the same concentration as
great white you would be using 18,000x the amount.... 5 billion/270.000
1 kilo each root and nute pack: 100 bucks
treats: approx 183 gallons when used at my dose soil or hydro.
My packs at
great white doses:
4400 grams @6 grams / 10 gallons will treat 7,333 gallons for hydro, and 1,466 gallons for soil.
Nute pack weighs approx 2.5 grams/teaspoon
Root pack weighs approx 3.5 grams/ teaspoon
8 oz can of
Great white (226.8 grams): 40 bucks
one scoop weighs approx. 3 grams
treats: 750 gallons in hydro, or 150 gallons in soil.
In sum, costs 2.5 times as much, but gives you 10x as many applications, @ 18000x concentrate, when used the same as
great white. PLease check my math because I coudl very well haev made an error.
The manufacturer has not used/tested this product for hydro, only soil.
It looks like I am going to have to set up a few tests of my own soon.
To date I have pretty much only been making my tea.
