Backyard Greenhouse Buying Guide 

When it comes to your backyard greenhouse, you’ll quickly find that there are styles and sizes available for almost every budget. While this is nice, it complicates the buying process because it gives you that much more to consider and compare. When you finish looking through the reviews above, you can use this short section to make your final choice. 

Size

How large does your backyard greenhouse need to be to accommodate all of your plants? For example, if you want to grow a large assortment of cruciferous vegetables, you’ll most likely want a bigger greenhouse. Maybe you want a smaller greenhouse to put your bigger plants in during the cooler winter months. If so, you could get away with a smaller backyard greenhouse. It’s a good idea to make a list of the plants you want to put into your greenhouse and take their size into consideration. This will help you match your final pick to your needs. It’s better to have too much space than to run out. 

Backyard Greenhouse 2 Size
You don’t necessarily need an enormous greenhouse for your home, but you should get one that is slightly larger than you need. This allows you to expand what you want to grow without having to buy another full greenhouse. 

Material 

Every part of your greenhouse should be sturdy. The cover should be a durable PVC material that won’t tear or break down with repeated exposure to sunlight and the elements. The frame should be a slightly thicker steel tubing with a powder coat that won’t rust or corrode. The connectors should be metal. If it comes with shelving units, they should have a slightly higher weight limit to support your plants and seed trays. It may be a good idea to spend more upfront to get a high-quality material that will last season after season. 

Plant Accessibility 

Maybe you want to grow an assortment of catnip and other ornamental grasses or plants, or you want to mix and match vegetables with flowers. Whatever you choose, you should be able to get to all of your plants to water and fertilize them without having to shift a lot of things around. Backyard greenhouses with dual entrances are very popular because it gives you a higher degree of accessibility, but you can reach all of your plants if you have shelving running along the walls while leaving the center clear too. 

Backyard Greenhouse 3 Accessibility
Many people choose to put their plants along the side of the greenhouse and keep neat rows in the middle. This layout gives them enough space to walk amongst their plants and reach every area to water and fertilize it as they need. 

Stability 

Your backyard greenhouse’s stability is going to be extremely important. If it’s not stable, it can easily tip over or collapse when the wind comes up or if it snows. The frame will play a role in the overall stability, but it should also have anchor points. It’s popular to tie rope to anchor points and run them to stakes into the ground to help secure your greenhouse. Double-check the anchors and frame before you buy. 

Windows 

Your greenhouse will eventually need to breathe, and having windows plays a large role in it. The bigger the greenhouse is, the more windows you’ll need to be able to get a good cross-ventilation. Ideally, your windows will have screens on them to prevent unwanted bugs from slipping in when you have them open. You should have at least two windows, if not more, on your greenhouse. Make sure you can prop or roll-up the door too. 

Space Requirements 

How much space do you have for your new backyard greenhouse? For example, you may need to go smaller if you have a balcony or a rooftop garden. If you have a full backyard, you have to be able to find an even piece of ground to set up your greenhouse and anchor it in. Most greenhouses will have their dimensions listed right on the description or box, and you can take these dimensions and compare them to your area. Make sure your backyard greenhouse has adequate space around it. 

Backyard Greenhouse 4 End
Make sure you have enough space to support your new greenhouse in your yard, and pick on that will withstand exposure to snow, rain, and other weather conditions without breaking down or wearing out. If you take your time, you can easily find a greenhouse that lasts for years.
