Cooling my DWC buckets

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.:hippy:[attachment=o229586]
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.:hippy:

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