Tweaking my Hot Bed

I had to make a few adjustments today. We had a lot of rain over the week end, and the weight of the accumulated rain pulled some of the plastic loose, so I cut some boards to better support the insulated blanket It is very cloudy with highs of about 35 degrees until Thursday. With the bed covered with the blanket the soil temperature at soil surface was 60 degrees, a little cool for tomatoes and peppers. Since I am not getting any solar support I placed a small space heater inside, which raised the temperature about 10 degrees.

Hotbed on the 5th day.

It has been cloudy and even though it was only 20 degrees this morning, the soil temperature is about 90 degrees. When I opened one of the sash to take the picture steam just rolled out.

Hot bed prepared and ready to go. Ready to plant seeds.

Here you can see I removed the manure I had been storing in my pit. Then I began to fill , water and tramp it down as I went. The hot bed is 3 feet by 12 feet. It took three pick up loads or three cubic feet of manure. Then I took compost and screened it through hardware cloth. It took about half a yard to fill it with 4-5 inches of compost to start the seeds in. I raked it smooth and put the covers on top. What I have read is that in 7-8 days the weed seeds will have sprouted. The bed will have heated up and cooled down to a temperature suitable for seed germination. After the weed seeds sprout, they can be killed and the garden seeds planted. So some time next week I should be able to start seeds. Today it is snowing very hard and we might get 8 inches, so I finished just in time.

Another Load of Horse manure

I went and got a second load of manure today. It is now covered and protected against the elements. I don't really need it for about another ten days, but now I am about ready. When the time comes to water it and pack it down I will probably need about one more load. It is just piled loosely, with the cover it won't be frozen when i need it no matter how cold it gets in the mean time. It is so much easier to do this work when there is no snow, so this week was a good opportunity. Now I have to hook up my electricity. You can see the romex I ran from inside the house. Also I am going to hook up a vent fan and install a vent for fresh air to enter.

Horse Manure and Straw for the Seed Starting Hot Bed.

I went and got a load of manure and straw from some race horses yesterday. It will take at least one more load. I am stockpiling it, so I have it ready to "charge" the bed on February 26th. I will have to dig it out of the pit, water it and tamp it down as I go.

Hotbed/Hothouse progress

We have an ice storm coming and I wanted to build the hotbed structure before the lumber got covered with ice and snow. Right now the ground is dry here but it was about 25 degrees outside. The official soil temperature is 26 degrees, and next week it is supposed to be pretty cold. I covered both sides of the windows with plastic to have an insulation layer. I still want to run electricity to it, and have a vent fan to keep it from overheating, and a little electric heater for back up heat. I have an insulated blanket to cover it on real cold days or nights. The insulated blanket is what concrete workers use. About February 26th is when I want to fill it with manure and soil.

I bought the lumber for the hothouse today.

So far with the old doors I bought and the lumber I have $80.00 invested in the project.

My 2013 seed starting hotbed.

I don't like starting seeds indoors, it takes up to much space, all the lighting etc., problems with damping off, and memory's of children filling cribs with plants and dirt during nap time. So I am working on this years hotbed, in a different location and dimensions that last. I made mine 4 feet deep last year which is too deep to reach in safely. So this year it will be 36 inches deep. Also I bought some old screens today for $15 that I will cover with two layers of plastic. Last year I used glass windows. Some broke, and I thought they were dangerous. I only dug 2 feet deep last year, and I have gone 30 inches this year. The length is 12 feet. I plan on using a squirrel cage fan for ventilation, and perhaps a small auxiliary heater connected to a thermostat. I found on the "net" a rather simple design for the frame.
