As soon as my light went off I entered the chamber to see how much, if any, light was leaking through the vent flaps. To my amazement...barely any, if at all. I think, just to be safe I will add a piece of cloth or something that is a bit larger than the vent opening so the vent stays down but is light enough to let fresh air through. My exhaust fan stays on all the time. Should my exhaust fan be off when my light is off?
SeaLevelGrower Reviewed by SeaLevelGrower on . GROW TENT LIGHT PROOFNESS I have 2 questions: 1) I have a 4x8x7 XXL grow tent in my garage, which I occasionally work in, and I am worried that light is leaking in through the vent flaps at the bottom. How can I fix the flaps to ensure no light is entering while im working in the garage with the lights on? Its not DIRECT light, but the lining is very reflective and I would imagine that light is getting to the plants. The vents are about 4x16. Also, I am having lights on at night for temp reasons...so dark period Rating: 5
