I cant believe this works so well.I run DWC in 3 gal
buckets all seperate systems and have dealt with temps
really too high (mid 70 s) I took a starter tray from the nursery
and placed 2 buckets in each.Filled trays with H20
and directed a fan to blow over the water. Then I moved
my pump outside the closet.Im down to 63 deg. in my solution
Ill have to rase it mayby whichmeans my dangling root zone is
probably a nice blustery 65 or so.That should help keep
the nasties away.PA131090.jpg
thats just above the 60 mark at last check.

what do u do about humidity?

It hasnt raised any with the addition of the hole I cut in the opposite
wall.The fan blows over the water acrossthe space and righyt out
the other side.It took a little to light proof my closet again but it really forced me to finally vent my growspace properly.My solution temp did eventually
climb to 66 but thats still 6 deg.better than before not bad for
a redneck attempt though.Pulling the pump out of the closet had no affect
on the temp at all.

was it the water that actually lowered the temp, or what it the better ventilation.... hmmmmmmmmmm?? :P
