Many gardeners try to extend the growing season by using cold frames. This can allow you to grow more of what you eat. According to Mother Earth News, you can extend the growing season even farther by erecting a potable greenhouse.
Homemade portable greenhouses of about 10 by 12 feet can be more affordable than store bought cold frames that are only 4 by 4 feet. It should be easy to build using only items you have or can readily buy off the shelf. You need to be able to anchor easily when in use and to move it when not in use.
A portable greenhouse not only provides a warm, sheltered place for your plants but because of its size, provides you with a warm, sheltered place to work. You can stand up inside of it – a definite advantage over low-to-the ground cold frames.
It works on the same principle as a cold frame, capturing heat from the sun and cutting out the chilling, drying effects of the winter wind. If you intend to grow cold hardy crops, you don’t even have to heat it.
You can harvest throughout the winter and get an early start on spring plants. Your tomatoes will be ready for transplant weeks before they would normally be ready. All you have to do then is sit back and wait for the harvest.
