Cooling Reservoir
In following picture you can see large cooler that we applied after running into problems with heat. Air temps were about 25°C with lights on, which wouldn’t be problem if we were growing in soil or other “solid” medium. But in aeroponics (bubblers) there is limit in about 24°C which you cannot cross otherwise your roots will start to deteoriate… Basically they don’t have enough air, quickly lose their naturally white color and start to decay.
There is additional cooler in the reservoir (see pic). Through transparent lines (these with green line) circulates pure water from cooler to another room in which we have just another 100 liter barrel. That room is cooler and serves just to cool water in nutes reservoir.
Temps are crucial in aeroponics and you will learn that just in the first round. We have learned this the hardway, because unfortunately we have started in winter and summer surprised us.
Don’t even bother to build this if you can’t supply water cooler than 24 degrees Celsius.
