I don't give them any attention until after I top them and move them into 3 gallon pots full of FFOF. My tap water is 7.1 and the pots get down to 6.9 by harvest day.
That's what they say. My water is 7.1-2 out of the tap and the plants seem to stay no lower than 7.0. Strangely, everybody raves about the weed grown. Not sure if I'm doing something wrong. Should I add some sodium biphospate?
I tried it once many moons ago. Two tablespoons in a small glass of milk. I could taste the nutmeg all afternoon. I sorta got high. Smoking rosemary was better. It really got me whacked. Don't recommend either.
