i have the ph in the soil good, as well as the water i feed them, i have lots of lights close up. I have organic soil and nutrients. I have reflective walls. What else can i do besides LST because its not tall enough to start LST, someone told me i could get a co2 dispenser, is there such a thing and will it help?
is there anything else you can do for......? what? your not asking a specific question. co2 is used primarily in flowering stage.
