Our Greenhouse Project

Spring thaw has happened, the snow has melted and the ground is not frozen any more.  So, back to work.

Installing a Greenhouse Vent Opener

In our greenhouses we have a large window at one end and a door at the other end.  We have always manually opened them when the weather gets warmer or the sun shines and heats up the greenhouses before the end of winter.  We have intended to install automatic vent openers for quite awhile, but kept putting it off.
Today two Bayliss Mk 7 Autovents were installed in each of two greenhouses.  I decided to build a new window vent above the door near the peak of the roof.

The first step was to build a inner and outer frame out of 2 x 2's.  I cut the pieces then drilled holes to screw them together and screw the frame to the greenhouse beams. Both frame pieces were glued and fastened  together with screws.

The frames had a twist in them so I used 25 pound weights to straighten them while the glue dried.

Weights Used to Straighten

After they dried, I installed two hinges.

The next step was to fit the vent in the spot where I wanted to install it, and cut a hole in the greenhouse panel.

Then the frame was screwed into the 2 x 4 studs in the greenhouse.  A scrap Polycarbonate greenhouse panel and foam strips were installed. Then the vent opener was installed.

Finished and Adjusted

MARCH 1ST PLANTING SCHEDULE

   The end of February and March is the time to get the ground in the greenhouses ready for this season.  We dig in rotted manure, start lettuce, radish, green beans, and carrots in the ground.  We also start seedlings in peat pellets, such as bell peppers, and tomatoes.   The vegetables that aren't freeze tolerant, which we start in the greenhouse floor we cover with a second hooped covering for double protection.

Fourth Greenhouse Project

Our family lives in a severe high desert climate where the winter temperatures can reach -25 degrees, and summers are short and windy.  We have learned through trial and error how to significantly increase our vegetable and fruit production, and have had increased success with the animals that we raise for food.   We have succeeded in growing foods that traditionally have not survived in our area.  This is an excerpt from our e-book, Greenhouse Growing: How We Do It.

We have had great success with using the greenhouses that we designed and built, and are in the process of building a fourth one.  My son and I started it in the fall and now the snow has fallen, so it will get finished in the spring.  Below are some pictures of the beginnings, with the last two showing the greenhouse on hold until spring.

Growing In An Unheated Greenhouse

This is an excerpt from 'Greenhouse Growing and Construction: How We Do It.

If a deep freeze is forecast, then a plastic sheet or cover can be put over the plantings in the greenhouse for extra protection.  We also use plastic coverings in the fall for some plants when night time temperatures fall below 25 degrees or so regularly.

We left a plastic cover over some spinach plants in our unheated greenhouse.  With protection of the greenhouse, and  the added protection of the plastic cover inside, these spinach plants were able to survive an outside temperature of 22 degrees below zero last Wednesday February 5th.

Spinach survived 22 below zero.
