Greenhouses can extend your growing season, allow you to propagate plants from your yard, and the yard of fellow gardeners, and let you grow tender or delicate plants you might not otherwise be able to grow. I’ve seen lettuce and spinach grow in a greenhouse when there was a foot of snow on the ground. An old gardening friend of mine would use her greenhouse to pot up all her volunteer seedlings from her yard, grow them in four inch pots in her DIY greenhouse, then have a plant sale to raise money for her charity. Any way you look at it, if you’re a serious gardener, you would love to get your hands on a greenhouse. So how do we solve problems at TGG? We DIY greenhouse projects, of course!




We found you some great DIY greenhouse projects and plans that range from a temporary row solution, all the way to a full size backyard greenhouse! Before you pick out a project, read over our “getting started” tips to help you choose, site and start your DIY greenhouse. Our feature project, above, is a mini window greenhouse by ‘Crafts Ala Mode‘.



Getting Started Planning a Greenhouse

  • Position your greenhouse running lengthwise east to west. This will give it the longest stretch of daylight each day.
  • Make sure your greenhouse will get at least 6 hours of sun in the winter.
  • Remember, if you plan on having electricity in your greenhouse, site it close enough to your source.
  • Try to position it away from kids play areas.
  • Make sure your DIY greenhouse has a working thermometer. You will need to pay attention to temperature unless your system has automatic venting. In the winter, the minimum inside temp should remain between 45-60 degrees for active growing. A sunny winter day can quickly heat up the interior of a greenhouse, even if its freezing outside. Be sure to open vents and allow cool air to enter when the temps rise too much.

Design Dreams by Anne‘ created this baby DIY greenhouse from old storm windows. This may be one of my favorite projects! It may not be air tight for all you who are looking for that, but I think it would do a very charming job for the most of us. Did I mention it’s charming?

    Hi, great diy greenhouse ideas. I built one a few years ago. I used 3m plastic, my vegetables flowered but never produced. It eventually ripped due to wind and fell apart so I had to take it all down. Anyway I’m wondering what the deal with the plastic and the plants not producing. Thanks

      Did you allow access for pollinators such as bees?

    I have pinned the greenhouse made from plastic water bottles. The instructions are no longer on the site. Would love to have the instructions. It was posted by Ana White.

    I bought a few plants at an early bird sale in April had to think of a quick and easy greenhouse for my new plants. I used my large wire kennel. We had not used it for years and I didn’t think the dog would miss it. I set it in my garden and wrapped it with clear plastic. I wrapped the door separate so I could use it to check on the plants. It worked like a charm and the plants thrived for four weeks. Now I know I can hit the sale next spring!

      That’s a great idea!
      What did you use for the top roof supports? They have 10x10x6 foot chain link kennels with door for $299 at tractor supply that I think would make a great greenhouse base.
