The Ultimate Guide to Picking the Best Greenhouses

For the proverbial green thumb, installing a greenhouse in your surroundings is a no brainer. These simple structures are great for sowing your seeds, tending to your delicate plants and housing those tricky overwintering crops. You can grow pretty much anything you want in these reliable little hothouses. When it comes to greenhouses however, there are one too many options on the market and too much advice on how to install it in your space. Luckily we have put together an easy instructional for you DIY plant lovers, so you can get the perfect greenhouse for you.

Step 1: Get Rid of All Things Old 

When it comes to revamping, the rules of good decor apply - the outdated simply must go. Start by tearing down any old structures that you already have. You can always choose to grab a sledge hammer and a pair of gloves and get down to business yourself but we say that it is wiser to hire a professional to do a thorough job. 

Step 2: Get Clean and Even 

Clear out any of the remaining debris and ensure you have a clean space to work with. Once you’ve ensured the space is free of anything that might halt your progress, you can start with leveling the ground. The surface needs to be even and you must check if it's flat with a spirit level and then start on laying the foundational support. 

Step 3: Get Your Measurements  

Once you have decided on the space, ensure you take accurate measurements. This will help guide you on what the size of your next purchase should be. While a frame does say 6’ x 8’, it is often bigger and takes up more space, so make sure you have some extra room. Now you can plan how to place the frame that you have and how to make space for any accessories you need like a solar powered light or a circulation fan. 

Step 4: Get Your Frame in Place

Now that it is time to start building your greenhouse, it is important that you know where to start. A good place to begin is the roof and it's a good idea to put all the clips and bolts into separate posts before you start. Lay out the individual pieces and get to assembling the structure section by section and then fasten it together. Know that when you add the glass some adjustments might be required. Decide on where you want to place the door before you start on the glass.

Step 5: Get to the Windows

This might be the most tricky thing so be careful, you need to plan out how you are going to position the panes. Ensure that all the beams offer sufficient support and you can also consider installing the automatic window openers and louver vents at this stage. This will keep the temperature inside even and prevent over scorching of your sensitive plants. You can also fill in the gaps with a silicon sealant and use white asphalt roof panels along the ridge beam.

Step 6: Get to Planting 

Now your space is ready to house your leafy friends, a good place to start however would be outside the greenhouse itself. You can paint a lush picture inside but it does not bode well if the space outside is dry and arid, so cover the area with green grass and some cheery shrubs to start off. You can then get to planting your favorite flowers, herbs, or even some seasonal vegetables inside your brand new greenhouse. 

Now that you have an understanding of how to put your dream greenhouse together, it's time to decide on the best greenhouse kit for you. You will need to decide on the size, style and the kind of windows you want before you buy the one for you. While this can have you scrambling, carefully assess your current needs and our rundown of the best greenhouses should make the choice easier.
