my growbox is completed, want to run over the edges/frame inside of the box to seal any cracks of light. Do most people use Duct Tape? Or some type of sealant/filler? Inside is painted flat white.
Inside of my box, around the joints I used caulk that seems to work fine but i haven't finished the box yet so only time will tell Now my problem is sealing the cracks around my door, im torn between foam insulating strips or pipe insulation
