I have a 70 gal fresh water aquarium. Didn't want to add another variable to my first grow, but I'm think seriously about adding only tank water on my second. Really, i hate dumping all that tank water out every 3 weeks when I change out 20 gallons, ya know? I water the shrubs with it right now.
OP: I'm on 4.5 weeks flower. I am going to use molasses starting on my next water. What's your dose and frequency?
For what it's worth, I'm growing in organic soil and want to feed those little critters breaking down stuff in my soil.
Seems to me, happy, well fed plants are going to result in the best tasting bud. If the molasses makes my plants happy, I'm in.
