5 Greenhouse DIY Ideas Everyone Should Know

It’s easy price to create a backyard green house to grow your favorite plants all year round. It is possible to enjoy your favorite pastime year-round by using a greenhouse to keep your seedlings and plants chilly in the winter and warm in the summer. When there was a foot of snow on the ground, I’ve seen lettuce and spinach grow in a greenhouse. An old gardening acquaintance of mine used to pot up all of the free seedlings from her yard, grow them in four-inch pots in her homemade greenhouse, and then sell the plants to make money for her charity. Any professional gardener worth their salt would kill to get their hands on a greenhouse, regardless of how you look at it. Therefore, how do I resolve issues at Green Garden? I do our own DIY greenhouse projects, naturally!

How to Build a Greenhouse

I’ve created a list of DIY greenhouse ideas and designs ranging from a simple cold frame to a full-fledged greenhouse for your backyard! Start by reading our “How to Get Started” section to learn how to plan, design, and build your greenhouse.

  • Put your greenhouse so that it runs east to west. This will give it the longest amount of daylight each day.
  • Make sure your greenhouse gets at least 6 hours of sun every day in the winter.
  • Remember, if you want your greenhouse to have electricity, put it close enough to the source.
  • Try to put it away from where kids play.
  • Make sure your DIY greenhouse has a thermometer that works. Unless your system automatically vents, you will need to pay attention to the temperature. For growing to happen, the inside temperature should be at least 45 to 60 degrees in the winter. Even if it’s cold outside, a sunny winter day can quickly warm up the inside of a greenhouse. When the temperature gets too high, open the vents to let cool air in.
