ph is often different depending on whether you are growing in soil or hydro, in hydro a range of 5.5 -6.0 is maintained in soil a range of 6.5 to 7.0 is usually maintained.
bejay Reviewed by bejay on . Confused About Correct PH ok i'm confused over what the PH should ideally be? I read on a thread PH should be 5.5 - 6.5, i've been watering at a PH of 6, and i've just read somewhere cannabis plants like a neutral PH of 7. Can someone please let me know what i should be aiming for as i don't wanna be hurting the plants. Thanks in advance for anyone who can give me some advice ;) Rating: 5
