I was looking for simple for ideas for the flowering stage instead of taping everything in the grow room which is time consuming. I found a blackout curtain on amazon. Anybody ever tried one? Would it work if i dont want any light to pass through the grow room?
I have blackout curtains in my grow room and in front of my levolors. I use them to block my lights when tent is open. Most blackout curtains do not fully block light, especially cheap ones.
