I'm using a hydro kit that recomends a ph of 5.5, I thought pot grew best at a neutral ph of 7.0 ? billbeau
Cannabis likes the ph to be slightly on the acidic side so if you keep it between 5.5 and 6.5 you'll be fine.
I was wondering about that.(difference between the two) I have it closer to 6 right now and they seem to be doing fine. Growing like little weeds you might say.(hehe!) Thanks
