would you beleive that temps are fine, it was the humidity that got me, it was torrental in there last week, floor and ceiling both drowned wet with it dripping like a tap..
sorted now and just about bone dry again.. think its down to the plants being on 2litre feeds now and thats whats driveing it up, i have also switched from feeding in the morning to feeding at night and thats also helping it too..
got a bag of cement to draw the moisture from the air aswell, just give it a stirr each evening to stop it goin crusty altogether, also seems to be working....
