You can also use frozen water bottles to bring down the temperature in a rez. You just fill them 3/4 of the way full so they have room to expand when it freezes. Drop in a few at a time and keep some in your freezer to exchange with. This way you get cool water but you don't change the water level and no diluting of your nutrients.
Zandor Reviewed by Zandor 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
