So i have some little guys going right now and i had them under 125w cfl for the first 3 weeks and they're doing great. So being that this is only my 2nd grow and i fought with this problem the first time, and im still very wet behind the ears haha. Last night i changed over to my 400w ballast with mh, and mind you im growing in a small tent that is 48x24x66 (i think), anyways the heat that comes from the mh zaps out every bit of humidity i have, even with humidifier running its at like 20%. I live in upper michigan so considering its 17 below out right now, it is very dry season in the winter.. if anyone has any tips or tricks, i would appreciate it. money is tight so i can't just run out and buy some crazy awesome climate control system haha. anyways, thanks much to all or anyone that responds :smoke:
