Light colored buckets is the first and easiest step which I mentioned in my first post. If these thoughts dont sound like they will work then the sure fired way to fix the problem is to completely seal room and install an A/C unit just for that room but hell I dont carry an extra $200 around but if you do go for it :thumbsup:
I also have DWC running here and my temps in buckets runs right about 76 and never have had a problem with root rot.

Just my thoughts have a nice day
Lawl. $200? Try a thousand or more. A split unit a/c is $450+ for the cheapos and a good window unit cost about the same. Not to mention that wouldn't fix the problem at all. The whole point of sealing the room is to create a co2 enriched, HIGH temperature grow room. It would be hell on you're dwc as the room temps would most likely be 83deg's+, and a good co2 controller is $500, plus the co2 tank and regulator. I'm probably forgetting a bunch of other things, oh well, you get the point. And by the way, mid 70's on rez temps is just asking for problems.

Dopest's "Cooler" DIY Chiller - International Cannagraphic Magazine Forums
And heres a thread on the cheap 5 gallon 1/12 hp chiller drops 100gal's 10 deg's and 30 gallons 30 deg's.

I would suggest putting the coil in a seperate resovior, $30-$40 10' titanium tubing, and pump the nutes through it, this way the coil won't corode and you can place the compressor and everything else outside the grow. I'm in the process of making a 11,000btu chiller from a old floor unit a/c. :rastasmoke:

P.s. The real hillbilly water chiller involves a regular cooler with two holes in it, for a hose to come in and out. Ice bottles in the cooler along with 20-30ft of tubing inside. Input and output plumbs into the controller bucket/rez/buckets. pump size not that important, if you end up with too much cooling power just poke some holes in the input hose near the pump. Once you get the temps under 70deg's you're girls will be a lot happier.
helpinOG Reviewed by helpinOG on . DWC Water Temp Problems Hey guys, since ive gotten so much great feedback from the other two threads i have posted, I thought i would ask you guys another question. I'm runnin a DWC setup and have been having problems with root rot due to my water temps bein about 82 deg farenheit. My question to you gurus is what is a good way to keep the temps down? The space i have the ladies in is in the air conditioned house, but all the lights seem to be heatin up the water temp. The room temp is about 72-75 deg farenheit. Rating: 5
