So, I've been researching and making some purchases, such as a 400watt LED (120 Watt actual) and I'm waiting on a 48" X 24" X 60" grow tent. I've been emailing back & forth with Seedman, they've been exceptionally helpful. One factor that fascinates me is the employment of CO2. I would like to know what, if anything you members use. I pulled up a post from this past Summer (OP Jayv) where his/her generator failed for a while. My 1st grow will only be two plants (maybe one) so I won't need much.
