Twin Wall Planning

Well I decided to plant my first seeds yesterday. Looking at the temperatures for different plants I decided to just see if I could get some herb's started since it is still 20-30F outside. I'll just grow them inside until I can get the greenhouse to warm up. Speaking of the greenhouse I finally figured out a way to add an extra layer. I'm going to build a pipe structure over the top and attach it to the back wall since I can accomplish that with one piece of glazing plastic. I'm trying to get 1 1/2 inch of space between the layers of plastic glazing since that is what I have read is the optimal spacing. At this time the plan is to use 45 degree elbows, 4-way joints, and redwood strips to build the frame for this second layer. I'll post pictures as soon as I get it done. I'm curious to see what this combined with a wall of water will do for the ground temperature inside a wall of water.

Getting ready for an early spring

I don't know what the weather will do but I am hoping to have an early spring inside of my greenhouse. My goal is to start my seeds in the house on January 2nd. I'm thinking that by the time they are ready to plant I will be able to have the greenhouse warm enough for them. I believe I've figured out a way to cheaply make a double wall of plastic. If I place a grid of 1 1/2" pipe over the current layer and then fasten it down and cover it with a second layer. I should be able to gain some insulation value with minimal expense. I'm also planning on making an insulated door. I'm hoping to do this with my father over Christmas break.

Since I last updated this blog I was able to finish insulating the end wall but I haven't sealed it with foam yet. I did move in some compost, it still needs to be mixed in with the rest of the dirt, and clean up the old plants. The garlic and onions were still grown last time I worked out there but I haven't checked them lately.
