Chocolate Chunk + Purple Hindu Kush in Flood & Drain coco/perlite by Bandit420

[doublej]

I'm 8 ft underground in a cellar with 8ft tall cement walls 1 small window I have blacked out in a damp wet location. We have a return air system to circulate and exchange air that helps a lot but it regulates it around 65- 70% so I have to drop it from there, except in the winter. If a duct works for SF I could add a heat duct off the dehues intake and run flexible 6" duct off that into the tent. something like these. I could glue that to the intake and flex duct off it ....no??? View attachment 117785

I was looking at making something like this to keep the air off the leaves cuz my dehuey sits in the tent... might make your situation easier, I'm going to try cardboard and tape and just cut it in pieces and tape it together.
It's the design idea here that's important.....
