If you want to be able to enjoy fresh lettuce all year round, a greenhouse is just what you need. If building one sounds like a challenging project, don’t worry. We are here to help you out. Today, we’re going to provide you with 5 tips on how to build a greenhouse and 5 greenhouse plans to inspire you.
How to Build a Greenhouse – 5 Useful Tips
1. Think About the Size of Your Greenhouse
The first thing you should consider when it comes to building a greenhouse is the space you have available in your garden. Some people are lucky enough to have a large garden where they can afford to build a huge greenhouse. However, if you are not one of those people, and you only have a limited amount of space in your backyard, you have to think about the right size of your future greenhouse.
One of the best greenhouse sizes that you could decide on is a 6 feet wide and 12 feet long one. Remember that if the greenhouse is smaller, it will be more difficult for you to control the temperature inside of it.
2. Choose the Best Location
The size of the greenhouse is not the only thing that matters when it comes to making sure your plants develop properly. It is also extremely important to think about the exact place where you’re going to build one. Since your greenhouse is going to need plenty of sunlight, we recommend you to build it facing south.
Any other structure in your backyard, including the house itself, should be north of the greenhouse. If your garden doesn’t allow for a southern exposure, the next best thing is a western one. You might also want to consider strong winds. Build the greenhouse either leaning on the south wall of your house, or near a fence or some taller shrubs.
3. Consider Heat and Ventilation
No greenhouse would be complete without ventilation that releases some of the moisture created by the heat installation. If you don’t properly ventilate your greenhouse, you run the risk of your plants rotting. When your plants can’t get their heat from the sun and the outside weather, you can use a generator to provide them with the necessary warmth.
Ventilation can be obtained by simply raising the cover of the greenhouse and securing it with a log. You can also install vents in the ceiling, which you can open as much as you want depending on the weather conditions.
4. Choose the Right Materials
One of the most important things that no greenhouse should lack is plenty of light. Since the amount of light your plants get depends a lot on the materials you use to build the greenhouse, make sure you choose wisely. For instance, you have the option of making a greenhouse entirely of glass. However, you should know that this is also the most expensive option. So if you’re on a budget, you might want to consider some other material. You can try using polycarbonate, which is a material similar to plexiglass. It is designed to protect your plants from UV light. Moreover, it is quite resistant to more extreme weather phenomena such as hail storms.
Finally, you also have the option of using plastic sheeting for your greenhouse. This is the cheapest option, but it also doesn’t last as much as polycarbonate. Still, some plastic sheeting is UV proof as well, and it can protect your plants from damaging sun rays. However, if you decide to use plastic sheeting, make sure to choose a thinner one. A thicker one would block out some of the light your plants need.
5. Think About How You’re Going to Water Your Plants
Finally, the last tip on how to build a greenhouse we wanted to focus on is related to watering your plants. Here too, you have more than one option. If you have a small greenhouse and you’re always available to water your plants as needed, then you can simply use a watering can and do that manually.
However, if you’re away from home a lot, or if you have a large greenhouse that would take a lot of time and effort to water manually, you can invest in a semi-automatic watering system. Also, we should mention that there is something you can do to avoid wasting water. What, you ask? Well, you can store rainwater that falls from the roof of your greenhouse.

5. Garage Greenhouse
As we’ve already mentioned in our list of tips on how to build a greenhouse, you can always use one of the walls of your house as a lean-in for your greenhouse. The example in the picture below is quite straightforward. You can simply plant whatever you want next to a wall of your house. Then, cover the plants with plastic sheeting whenever the weather gets too cold. Placing the sheeting on some PVC pipes is a great way to make sure the structure is steady and won’t get blown away by the wind.
