Mr. C, $1500 for an 84 plant grow? The hydro store may be ass fucking you.
I pay 125 bucks for 5 gal of a and b aqua flakes. Used half to grow 15 lbs with 10 lights, plus overdrive, kool bloom, calmag, and epsom salt. I think a lot of the additives can be omitted, or used much less. Especially some of the newer shit like Nitrogen boost, and watered down Si.
lol, no
100 gallons every 3 days is watered.
Base nutrients are $80-90 per 5 gallon cocos, so 160-180 for base. Multizyme, Roots Excellurator, Top boost, Bud XL and I use Atami Tabzz instead of shooting powder. Some of that money goes into other products.
