yea that might be a problem.. but i thought .. why use a 8-10 inch pot for growing plants that will only end up to be 16-20 inch tops.. cant i just stiack to say... a 6 inch pot... leave about 5-6 inches for the light( put a steel mesh between the light and the plant(idea stolen

)) then leave about 2 ft for plant growth... with an lst method or something like it i could have a decent yeild per plant ?
ive seen lights like.. almost touching the plants how close is to close ?
( i like my room not burnt down

)
