I am using 6X40w flo = 240w
I was going to add 2 12w incandecent about 1 foot from buds with a fan on them. I am lackin in venting. Still building it. Plants get plenty air in Light hours. They get plenth breeze during day. The light temp is OK with the fan on them. I was gonna use the two 120s just 4 2-4 hours. To be sure.
Thanks
