Thanks...I'm trying to keep them from being too green now. I just cut back my feed a tad bit this week. Those holes are vent holes. It's a cheapo tent off ebay that I had in storage, so I decided to use it for veg in this run. My flowering tent is double this size (4×4). I like these holes a little better for ventilation, because they seal better than the other tent with the sleeve, to me. They have little screw holes for the bracket that my connects to my fan, which makes the suction that much stronger. Those
Gorilla Grow Tents are beasts, but name brand tents are way too over priced imo, when you can get one off ebay for 1/6 of the price. I'm not sure what the 4×4 Gorilla goes for, but I think it's like $500-700 dollars...this tent was less than #100 including shipping and serves the same purpose just fine. There's some minor light leakage around the meter holders stitching, but my grow room is light proof in general. Anyway, sorry for the rant. Update will be in a few hrs when lights come on...been super busy
