This is a cooling unit I’ve built to control the solution temp of my DWC buckets.
In the right foreground you you see a pink box.
That is ducting (made of Owens Corning pink) surrounding my AC unit.
At the bottom of the ducting you may be able to see the round flex ducting that send the cool air into my cooling chamber.
At the back of the cooling chamber is an exhaust fan to pull the cool air through the chamber.
I built it for this grow (first time I’m using it) and so far it’s kept the solution between 10-15 degrees F cooler than the grow room air.
