Hello GC, first grow is going good so far, 3 days after planting, I need a way to vent my closet out. My closet is 48" long, x 28" wide , and 81" tall. So it's a big rectangle, I need a way to rig a fan an carbon scrubber soon, it's not even flowering and I small the good ganja smell a little bit. Not good for visitors and when my grandpa comes over. I was planning on making a hole to the attic, and having air being sucked out, so to make a hole for ducting, how do I do that.?
