. I am off grid so I try to keep my power usage to a minimum there to keep my solar system happy. wish that free energy growing thread was still going.
I have a 16" louvered exhaust fan im putting in my south end wall and a motorized intake louver in my north end wall.
Most of ventilation will be from the roll up sides. I have motors to automate the rolling up by thermostat that I'll be putting in, in a few days with my exhaust. Right now I have a hand crank that I stole off another greenhouse for a quick fix. Lol.
Most places in the U.S. has real cheap pellets. Definitely the north west and north east. Cheaper then propane and natural gas by far. Only thing cheaper here is regular old cord wood. But wood stoves can't be automated. Also, I really would hate to have to trench a line 50ft from my propane tank.
Here's a picture of my temporary roll up sides.
