I pulled apart a $54 dorm room fridge I got at Lowes and stuck the freezer part in a 25 gallon res and put a box fan pointed at the fridge for about a 20 degree drop in temps.. if that helps anyone.
Aaron385 Reviewed by Aaron385 on . Hydroponic Water Temperature ideas I'm looking for some ideas on how to cool the water here. 5 Gallon bucket with 3 gallons of water in it. Aeroponic delivery. I dont have a thermometer (low budget DIY project), my guess is that the water is between 80-90F degrees. I read in some other threads where u guys say warmer water doesn't hold much oxygen, but in this setup the roots are suspended in air/hydroton and being sprayed by water so is the water temp even much of a factor in this case? Some pics to help Rating: 5
