I think that there is a huge margin for error.....if your plants are healthy....it's the best you can do.....I put stuff in my pots that blew my buds up huge..........but the flavor quality suffered. The best weed I ever grew was with the organic dr earth system, a happy medium between yield and quality......without the quality flavors I will never be happy....no matter how stony or quantity my harvest is. I just checked and I have 8 strains idling, I just wish I had 10 1k hps lights and all the support equipment to run em, I would grow those low yielding strains and close my eyes, but I have patients who aren't as pick as me, and can't afford the top shelf products. I get 500$ an oz. donation for my top shelf meds...or I will burn it myself! I like my personal weed to be around 20% thc, and definitely indica, the strong sativas go to the meds I make.....I just don't like to be that high.
shoot I wanna be so High I can hunt ducks with a rake!
