Hey everybody, Baldy here. Just wanted to post that I got eveything all set and running. Got a 4X4X8 tent with a 600watt HPS, 1 inline 6" fan for the fresh air intake, One 6' Vortex fan on an Active Air speed controller, keeps the room at a constant 75-78 all day and night! Air cooled light with another 6" vortex fan pulling air through that into a home made "fan muffler" I made form a/c duct and some sound foam from the local guitar shop. Works great, can hardly hear it. Portable a/c unit on a temp control device set at 75, so it runs when it needs to, works great. Now all I need is the seeds to grow some amazing autoflowers! Everything sits in a small bedroom that is 10x12x9 feet high. Can't wait!
