These DIY Greenhouses That You Can Build In Your Own Backyard Are Incredible

Taking the time and care to grow your own food isn’t only deeply financially rewarding, but also nourishing to the body and soul. The ability to control the ways in which your fruits and vegetables are grown, rather than relying on large-scale grocery stores, will provide a healthier option for you and your family.

When it comes to home gardening, climatic conditions such as frost and freezing can make or break your yield. Creating a controlled environment for your plants to grow in can save your crops from those harsh environmental factors. Here are some unique DIY greenhouse designs to help maximize your home garden’s growing potential…

Recycled Material Becomes A High-End Greenhouse

Looking at such a state-of-the-art design, it’s hard to believe that this greenhouse is made entirely from recycled materials. Not a single piece used in its construction was new. It’s quite amazing what can be made from repurposed supplies, and it’ll save a pretty penny not having to purchase new materials from a hardware store or home center.

The materials used for this specific greenhouse construction were all salvaged supplies from a renovation site, which isn’t only creative, but really very impressive – and eco-friendly.

A Portable Greenhouse That Takes Only A Few Hours

If you’re looking for something very simple and compact, this DIY portable greenhouse is the perfect option. The downside to this style of greenhouse is that it’s not meant for growing a plant to full-size. Instead, this is a seed germination greenhouse – a home where your seeds can get a head start with sprouting. Once the seeds have sprouted, the plants must be transplanted elsewhere.

For this project, you’ll need a large wooden box and a piece of glass that’s similar in size to the opening of the box. In addition, you’ll need two large wood screws, six small wood screws, four rubber O-rings matching the screw size, and a small piece of wood as thick as the glass. For easier portability, you could even put it on wheels. To learn more, visit the link below the image.

A Greenhouse For Your Tomatoes

Rather than constructing a large, elaborate greenhouse to hold all of your plants at once, you could simply make a greenhouse around an individual plant. This project is extremely inexpensive, requiring materials you may already have, or could get at a local hardware store at a minimal cost. And best of all, it’ll only take a few minutes to do each one.

By utilizing this method, you can limit the need for transplanting significantly. To make it, you’ll need a tomato pole, sheets of plastic, equally-sized wooden or bamboo sticks and, of course, a potted tomato plant. You can discover all of the details required to start this project if you visit the link beneath the image. 

A Greenhouse Made From Upcycled Windows

Here’s another great project for the environmentalists out there. This DIY greenhouse is made entirely from upcycled materials. The size of this greenhouse will be completely dependent on how many old windows you can get your hands on. You could make a small greenhouse with just a few, or elongate the design by adding on more windows.

For this greenhouse, you’ll need at least four large equally-sized windows, along with some reclaimed wood, nails, screws, and hinges. You could even add some shelves into the interior, allowing for more plant storage. Take note that heavy winds could blow this greenhouse over if it’s not properly reinforced. You can find complete instructions by visiting the link located under the image.

The Futuristic Greenhouse

This one’s for all the coding geeks – although, even with just basic computer skills, anyone could make this techie greenhouse, as the website outlines all of the instructions and code. You’ll need lots of materials to execute this project, including an 8GB Micro SD card, a 5.2 V adapter, a Raspberry Pi 3 Model B, servo motors, MCP3008, push buttons, moisture and temperature sensors, and many others.

The list of materials for this one is definitely longer than most of the other options we discuss. However, the items are fairly accessible and inexpensive, and should come out to a total of no more than $200. If you’re willing to invest the money and time, this robotic greenhouse is sure to impress. To learn more about the process, visit the link below the image.

Upcycled Glass Jars Turned Into A Greenhouse

YellaWood Greenhouse

Like the last one, here is another pre-made construction plan that you can simply follow to make a perfectly designed greenhouse. YellaWood, a well-known lumber company, has created a detailed plan that you can follow to create a greenhouse that is strong and functional. While YellaWood provides lumber, of course, you can use lumber from another source, or even what you have lying around.

For this project, you’ll need lots of lumber of different sizes, as well as some plywood, fiberglass panels, a vinyl or galvanized door, hinges, neoprene washers, and nails. If you’re interested in following this DIY process, you can find all of the necessary materials and instructions that’ll help you bring this project to fruition by visiting the link below the image for more info.

A Lovely Seedling Home

Here’s another home for your seedlings, meant only for their germination phase, after which they’ll need to be transplanted either to another greenhouse or into the soil. This greenhouse design includes a roof that folds down, allowing you to access your seedlings from above without much hassle. Not only does this make for easy tending, but it also adds a very sweet aesthetic to the structure.

Although this greenhouse is very attractive, it doesn’t require many supplies, and can be constructed fairly quickly by anyone with even a basic knowledge of woodworking.

Fold-Up Greenhouse

For some gardeners out there, you may not need a greenhouse in the garden space all year long. Wouldn’t it be great to have your greenhouse out when needed, and then be able to tuck it away the rest of the year, freeing up more space in the garden? That’s exactly what this DIY greenhouse does. It folds right up and stores easily in a garage or other storage area.

To get started with this project, you’ll need a few more materials than you would for a standard greenhouse, as this one needs to be foldable. But the extra supplies are well worth the additional cost. The creator of this design has outlined all of the necessary materials and instructions in order to create this masterpiece.

Greenhouse With A Fold-Up Top

This next greenhouse design is very unique, as its cover is hinged, allowing you to keep it up or down depending on what is currently needed in the garden. Though it may look a bit complex, the concept is actually surprisingly simple to build. It should take no more than one day to make this design a reality.

To build this greenhouse, you’ll need pieces of redwood of various sizes for the frame and top. You’ll also need some wood screws, PVC pipes, pipe clamps, chicken wire, wire mesh, plastic sheeting, zip ties, eye hooks, and hinges. As far as tools go, you’ll need a drill, staple gun, and miter saw. Visit the link below the image for all of the necessary info.

Greenhouse Made With Repurposed Windows

If you’re all for the upcycled window style, and want a full-sized greenhouse, this design is absolutely stunning. This is definitely one of the most beautiful greenhouses featured on this list. However, it’s also one of the most expensive. The person who owns the greenhouse featured in the image spent $1,695 on materials, and over $2,000 on labor, totaling $3,695 in actual costs. 

If you’re willing to make the investment, this greenhouse is sure to make a great addition to your garden. There are also thrifty ways of cutting down on costs by upcycling lots of the materials, and building it with friends rather than hiring workers. With these efforts, you may be able to bring the cost down to $1,000 or lower.

Portable Can Greenhouse

This can greenhouse is compact, portable, and incredibly simple to put together. The whole process, from start to finish, should take no longer than a few hours to complete. There are only a few materials you’ll need in order to construct it, which can usually be found and purchased easily. However, you can even use recycled materials that you have lying around.

The primary material for this greenhouse construction is a large plastic can. You’ll also need a sheet of transparent or semi-transparent UV-coated plastic, as well as screws, nuts, plywood, duct tape, a slat, and finally a bike tire’s inner tube. Some of these supplies may sound strange, but if you’re curious how they all come together to create this greenhouse, visit the link below the image.

Rooftop Greenhouse

Now here’s a new one. Did you ever think to put a greenhouse on your roof? For those with a rooftop that’s flat and spacious, this project might excite you. Rooftop greenhouses can be optimal as they receive maximum sunlight exposure, unless you’re surrounded by tall trees. They also allow for more space in the actual garden, allowing for more plants.

To make this rooftop greenhouse, you’ll need 100-liter plastic boxes, plastic pots and containers, buckets, wood of various sizes, UV-coated plastic, un-annealed wire, metal grids, and a few more hydroponic materials. You’ll also need to ensure that your roof can support the weight before you start. If you’re curious to see how this works, you can visit the link under the image to read the whole process. 

Greenhouse Made With Coffee Stirrers

This one is definitely one of the simplest designs on the list. Using materials you likely have lying around the house, or could easily find at a craft store, you could put this mini greenhouse together in less than an hour. This is a great option for gardeners who need a last minute support for their seedlings as they germinate.

To make this greenhouse, you’ll need 30 wooden coffee stirrers, sheets of cling film, a marker or pen, glue, a cutting tool, a ruler, and scissors. That’s all there is to it. To learn more about how to put this greenhouse together, visit the link located under the image for more info.

Complex Greenhouse

This next one is the greenhouse for those of you who want to go above and beyond. This greenhouse is potentially the most detailed of the whole list, incorporating many complex elements to add function and aesthetic value to your garden, while holding many plants through their growth. Some of the elements include a built-in mist system, as well as air filters.

This project won’t be as budget friendly as some of the others we’ve discussed, but it’s worth the investment for the beautiful structure you’ll end up with. If this project is of interest, you can look into the full list of materials and step-by-step instructions to get started by visiting the link located below the image for more info.

SerreMatic

Here’s another fancy automated greenhouse. This one is really special. It may take some time to set up, but after that, you’ll barely have to do any work. This greenhouse has a built in automatic water system that knows when to water, as well as a light adjuster to ensure your plants get optimal levels of light and dark. It even provides extra light on cloudy days.

Because the moisture sensors work with the irrigation system to provide optimal water, it’ll use only the amount of water that’s necessary, allowing you to save more water than you would with a traditional watering system. If you’re interested to learn all of the complex systems that go into making this high-tech greenhouse, visit the link located below the image for more information and instructions.

Greenhouse In A Jar

Here’s another super simple greenhouse idea that uses materials you’ll most likely already have, or can buy for almost nothing. Basically, all you need to make this is a jar. In addition, the materials list includes some rocks and nails. And that’s it. This is pretty much as simple as it gets. An added benefit is that this greenhouse is very portable.

If you like this concept, you could even make several of them and keep lots of plants together in your greenhouse jar collection. The process of construction is very straightforward, so you may already be able to see how to do it. If you still need some clarification, or want to get some tips for the best way to make it, you can visit the link below the image.

Touch Screen Greenhouse

On the trend of high-tech greenhouse designs, this one adds an extra exciting feature. This greenhouse operates through a touch screen. One thing to note is that this greenhouse is meant only for indoor use, as it wouldn’t be a good idea to expose it to water or extreme weather conditions. The foundation for the design is simple, starting with a mini greenhouse. 

You could opt for a prepared kit, or you could make one yourself if you’d like to go above and beyond. After you have the greenhouse, the rest is added on to it. You can be sure that the materials list for this one isn’t short by any means. But all of the supplies can be found fairly easily.
