i have bad news guys, i didnt hook up the heating vent i have set up for my box when it gets cold at night i hook some flex pipe to the intake of my boxand the other end that i have tapped into my heating duct , and the plants frosted up when the temp plumeted last night, frosted the seedlings all to hell. the lights were off during the night for there 4 hour off period so they just froze the whole time i had no lights or heat at all. so fucking dissapointed. seriously so fucking livid at myself.......
