In hotter climates, hydroponic and aquaponic growers have problems keeping NFT (nutrient film technique) systems cool enough--the trickle of water heats too much and tends to cook roots, even with white pipes.
My problem is I want to keep tilapia in a relatively cold climate and don't want to heat a greenhouse.
The problem is the solution....
What if I make black pipe NFT pipes high in the system mainly as the solar heaters--they will be planted in cooler seasons and left empty during the summer. I was thinking of tying them into the air circulation system since they will be at the upper layer of air with a bunch of intake holes to pull in warm air and circulate it through the mass.
Crazy?
