I dont have a fan, but ive been doing it the old fashioned way, fanning my closet 3-4 times a day, i hasnt been a problem yet, as the plant has been growing at a pretty good rate the last couple of months, probably because i leave the closet door open most of the time which makes it have natural air circulation.

First time i hear about the tin foil making hot spots, maybe thats why the leave tips have started to burn, ill try to follow your advice on putting white cardboard on the sides.

Yeah my closet its pretty tight, at first i was thinking of setting up a normal fluoro but cfl are easier to raise as the plant gets taller.

We dont have HomeDepot here, but i defn go with your advice on putting on a couple of 2700k lights when flowering
