well in How are you growing them? Are you trying a variation of the KBS system? From what aI can see in the picture you have the lights to high. Are you using air-cool tubs or hoods? Are you running a closed system with AC? Are you going to be adding Co2? What about humidity control? Air movement is a must, so what are you doing? It looks like you have plenty of room. If you are going to try KBS and grow trees then I need more details. A good KBS grow requires 5.5 sqft of space for every plant they get huge, but it takes lots of room to hold enough buds to make 1-3 pounds of dry buds per plant
