get some extraction asap...sweaty plants and buds don't mix :(
...have you been keeping an eye on your buds for the word we do not speak?
will you be using the same space next grow?
if you're not using the same space next grow and it's in a spare room i'd get the drill and make a tea bag grow room...but only if you've no use for the box :homer
if using the same space but can't fit the fans then i'd at least take the plants out and pre drill the holes for exhaust/intake...any hole's a goal :beer
your plants should get fatter in the last few weeks so the current risks/humidity will only increase
