sounds like you are on the right track. did you buy the ph tester? you are very lucky to have a fello herb grower in your garden store, perhaps too lucky. be careful what is said in that store though, because for him to know you grow and for you to know he knows how to grow, one of you violated the cardinal rule: DONT TELL ANYONE!! this rule applies double to strangers! i dont even talk to the burner @ the hydro store about what im growing. he knows what i am growing, thatswhat is cool about it. he knows, i know he knows, and neither of us talks about it. plausable deniability.
