It's been a few days since the last post. I have changed the flue on the big furnace, it wasn't drawing right.  I have most of the ground cloth down. There are two tanks set up with the next two in the process of being installed. I will have to put a support beam in to hold the ends of the grow beds, as I have changed the basic design again. Tomorrow is a ride to the big city with a neighbor. He is going to get some material for his house, and I am going to pick up the greenhouse supplies I have on order. Here are a couple pics of the progress so far.

 Here is the back up heater, that will double as a water heater if need be.

just so you know, the heater is the brownish thing in the middle with the fan on top  :)
