Most excellent. 18" has worked today. Hottest it got was just under 90. They took a good jump today.
The growbags are perferated on the bottom, correct?? Wonder if I should try those. As long as they are stout I will be in good shape. Probably it more in the room by the look of yours.

Maybe I should pull the humdity up to match you. Probably 30% in there as a guess so I could up in some water as well.

How many fans are you running on yours and how big? I use the 7" Target two speed specials. Up to two per room.
