glad to see you found something to get you through DJ

possibly use a metal reservoir, that may absorb some of that cool floor temp ? ...

I remember Weedhound (I think) said metal reservoirs were no good because the elements of the metal could potentially get in the water and affect the plants. Plus, I'm cutting them down in 3 days so I think it will be alright. Thanks for the advice anyways!

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.

Hey DJ,
I was surfin around icmag and saw in their DIY forum a guy that built his own res cooler out of an old water cooler. Thought I'd let you know in case you want to check it out for your next run. Cheers

I would say that's a 'reach' ... depends entirely upon the metal, and the acidity, etc., of the solution ... same could be said for Rubbermaid containers, leaching polymer resins, and/or, oil byproducts, into the solution ... see my point ? ... if I had high temps, I wouldn't hesitate to try it ...

Hey dejay did you ever get the ice probe? I'm curious how well it works. Right now a have a 55 gallon barrel Res. with 30 gallons of nuted water. Thats getting warm(75f) and I'm maintaining it with 2 one gallon ice bottles. It drops my temps down to 68f but climbs slowly. I'm curious if that probe will work for me. I kinda don't want to buy a water chiller cause that's an extra 300 watts.

No I never got an IceProbe, no money. I will probably pick one up during the winter of this year to use for next summer. From what I understand, they are best suited to 20 gallons or less as they are designed for fish tanks, so IDK if it will work for your 55 gallon. Hope you can find more info.

DJ,
Most of the people that were commenting on the DIY forum over there were picking up used water coolers for about $35, taking them apart and putting the cooling coil in the res and the compressor and heatsink standing next to it. It takes some room but the money savings seems significant, and it will cool a bigger res. with some playing with the thermostat.
P>S> thanks for the rep

Hey there just wanted to chime in shortly on the air pump location issue. I have seen water temps up to 90 degrees in my DWC scrogr tub. I know you mentioned trying to put the pumps in front of your AC.

A few thoughts.

1-check the bottom of your air pump. Is it hot? Some air pumps can produce more heat over time due to wear and can end up pumping hotter air through your res. I had this problem, replaced my pump-problem solved!

2-is the pump/ pumps COMPLETELY outside the growing environment? Even cheap diaphragm air pumps have no problem with long tubing runs. Keep those pumps in the dark and AWAY from the grow.

These two factors helped me bring my res temp down over 15 degrees. I know this isnt new info, but it sure worked for me!
