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.
