So this picture will show you the pipes coming up out of the ground and running to the roof of the greenhouse, Why??
Well at the transition between the black drain tile and the galvanized pipe is a fan. It is a 4Inch duct fan that blows 120 cfm. So what it does from 10 Am until 8 Pm is take the 100-120 degree air from the top of the greenhouse and blow it 2 ft underground. Best heating cables I have ever used
Infact it was past good and boarding on Extreme.
My ground temperature at 24 inches deep shot up to 85 degrees,
