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.
cigarettes42 Reviewed by cigarettes42 on . High Res Temps My Tri-Meter says my DWC res is 80 degrees. I read in Cervantes Medical Grow Bible that anything over 85 will damage the fine hairs on the roots and cause the plant to wilt and growth to slow. I have plenty of air, 40W worth through four cylindrical 4" air stones and a bubble rope, going to the roots, so if its not getting up to 85 should I still worry about it? So far, the plant is not showing any negative signs, and the roots are still white and thriving as opposed to brown and rotting, Rating: 5
