The construction of the compost water heater began
on 10/22/14 was construction was finished 11/1/14
It has successfully heated the greenhouse through the winter
from November to April and is still heating.
The water temps have fluctuated from 90 to 140 deg with an average of 105. When water temps were 140 I could easily heat the 350 gal fish tank to 85deg and keep it there with outside lows around 30deg.
Compost heating pile with pots on the ground and grass on top
4'x30' veggie patch cleaned up and mulched
Grey Dove oyster mushroom
Fungi in the garden beds
lots of fungi and worms
Corn, corn, corn
who's that guy?
Big kale, actually super sweet stuff, not tough at all
