For those of us who live in colder climates, knows five months or longer of winter each year, the advantages of greenhouse growing can be enormous. Gardening with a greenhouse allows an extended growth period can start and end month outside the traditional growing season outdoors in your climate.
Greenhouses may even let you grow plants year-round. Greenhouses can also produce a warmer mini-climate for plants that generally do not develop in your area, allowing you to grow many varieties of plants that are unique to your area. You can also use climate control management systems for efficient plant growth. For more information, you can search for a climate control manager via http://www.climatecontrol.com/climate-manager/.
When growing plants in a greenhouse, it is important to remember that inside the air temperature can be up to 30 to 40 degrees warmer than the air temperature outside. While the hot air is wonderful for your plants during the cold months of late fall, winter, and early spring, in the hot summer months, these temperatures can be a real threat to your plants.
When the temperature inside a greenhouse is too high, your plants can actually burn. In the hottest part of the summer, it is a good idea to add shade cloth in your greenhouse to help maintain the temperature inside down. When constructing your greenhouse, reconsider adjusting the roofline in an east-west so that the largest roof surface is exposed to the south.
