I usually cut a round access hole (netpot size)in top of bottom tub, so I can pump out or refill...then fashion blank and tape to cover the whole in order to keep out light. good luck, can't wait to see what you come up with.
latewood Reviewed by latewood 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
