I built the grow tent frame out of pvc pipe and wrapped black plastic all around it to seal out all the light. If i put all the plants in the center and leave like a foot between them and the wall with room for fans and what not will the light be losing a lot of intensity? I want to keep an area around all the plants so I can get in and work around them if I need to. Will the reflective mylar work well enough even with the gap or should I make walls within the grow tent with the mylar that are just big enough to surround my garden so they focus the light instead of escaping from my plants?
