Start With The Foundation

When it comes to assembling your portable greenhouse, you’re going to need a solid foundation. 

Make sure that the ground is level before laying down the foundation. If your site isn’t flat, then make sure that you have some kind of leveling device handy so that you can get your greenhouse in the right position.

Also make sure that the foundation is firm and stable when it’s laid out. No matter how well-constructed or sturdy your portable greenhouse may be, if its foundation isn’t solid, then it won’t be able to hold up under pressure from wind or rainstorms (or even high winds).

Set Up The Frame Next

Set up the frame next. From here on out, you will be constructing the greenhouse in a series of steps as outlined in your instructions. The first step is to build the frame of your greenhouse so that it is level and square (that means all four corners are 90 degrees). You can use a square or tape measure for this task.

Make sure each corner of your frame is 90 degrees! This is important because if one side isn’t at 90 degrees, then everything else won’t be either! If there’s a problem with one corner, check to make sure each edge meets at exactly 90 degrees before continuing with assembly.

Leveling: Use spirit levels along every horizontal surface inside your greenhouse to ensure it’s perfectly level—this process will ensure your plants thrive as well as prevent any water drainage problems due to uneven surfaces over time.”

Secure The Frame

You can secure a greenhouse frame by using metal connectors. We recommend you use at least one connector per corner and a third connector in the middle of each side or end. 

If you’re creating a simple, rectangular greenhouse with four sides, we suggest using two connectors per corner and three connectors in the middle of each wall.

Add The Glazing

The next step is to add glazing. Glazing covers the framing, protecting plants from wind and weather. There are many materials used for glazing, including glass and plastic. 

These are available in various thicknesses and sizes to suit your needs. You can purchase it at most hardware stores or online retailers like Amazon or eBay.

If you’re using a greenhouse kit with pre-cut panels (such as our Deluxe Greenhouse Kit), you’ll need to assemble the frame first before adding glazing onto it. Otherwise, skip ahead!

Add A Floor

Now that you have a good idea of what you need to build your greenhouse, it’s time to start thinking about how to assemble it. Assembling your greenhouse is not difficult; however, there are some key considerations that will help you get the most out of your greenhouse.

Choose the right flooring for your greenhouse. You should select a flooring material based on whether or not you have a slanted roof and also what type of soil conditions exist under where the greenhouse will be placed. If these aren’t issues for you then consider using hardscaping materials such as concrete pavers or flagstone tiles instead of wood planks. These materials tend not to absorb water like wood does so they won’t rot over time which means fewer repairs!

Install insulation under the floor if needed (to prevent heat loss). If possible use insulation blocks between joists instead of rigid foam sheets because they’re easier to cut when necessary (e.g., when adding ventilation slots). 

This can be done by simply drilling holes through them rather than having someone else do this work for free as part of their job description.”

Insulate The Greenhouse

Insulate the greenhouse with a vapor barrier. The best way to do this is by using a vapor barrier on the top and bottom of your greenhouse, as well as its sides. A vapor barrier is used to keep moisture from escaping through any holes in the wall of your greenhouse, and it can also be used to keep heat from escaping or cold from entering during winter months or times when it’s raining outside. 

The type of material you choose for your walls depends on what materials are most readily available in your area — but if you want an inexpensive option that will help retain heat well while keeping out rainwater, consider using plywood sheets cut into panels before putting them together with screws or nails (or both).

Install Vents

Install vents in the greenhouse. Vents are important for air circulation, and they should be able to be opened or closed as desired. 

They should be placed on opposite sides of the greenhouse so that one side does not get more ventilation than the other, which could cause uneven heating or cooling. 

The vents should also be adjustable—you want to be able to regulate how much heat gets into your greenhouse during winter months so that you don’t accidentally kill off all your seedlings.

Finally, make sure that any material used in making these vents is not susceptible to rusting or rotting due to water exposure (this may include metal).

Set Up Fans And Watering Systems

Once you’ve assembled the greenhouse, it is time to set up fans and watering systems.

There are several different types of fans to choose from, including:

  • Wall-mounted fans – these are easy to install and can be placed anywhere within the greenhouse. They usually come with a variety of speeds and settings so that you can adjust how fast they blow air through your plants.
  • Ceiling fans – these work similarly to wall-mounted ones in terms of being able to control the amount of airflow but have an added benefit of keeping insects out because they hang above the plants instead of sitting on top like walls do.

Fan placement varies depending on what kind you buy but generally speaking, it should be kept as close as possible without touching any leaves or stems so that only cool air reaches them directly rather than having some indirect contact with warmer outside air first).

Add Shelving And Benches

  • Shelving: The greenhouse must have shelving to place your plants on.

Benches: You can place benches inside the greenhouse where people can sit while working in it. This is especially useful if you plan on having more than one person working in the greenhouse at once.

Sink: A sink with running water allows you to wash your hands and other tools after use, which will prevent diseases from spreading between plants and help keep your greenhouse clean and sanitary.

Organize Your Space

The first thing you’ll need to do is decide where in your yard you want to put it. You’ll also need to consider what size greenhouse will work best for you, as well as whether or not there is enough room for you to maneuver the greenhouse around once it’s assembled. 

Once this is done, organize the space by laying out all of the materials that come with your particular model and step back for a moment you don’t want any injuries during assembly! Make sure everything is clearly labeled and organized so you know exactly where everything goes later on down the line.

Once that’s done, determine which parts are going together first before assembling anything else (like walls). This will help prevent confusion later on down the line when putting together certain sections of your portable garden structure. 

For example: if we were building our own portable greenhouses from scratch without instructions provided by manufacturers like ourselves above here at Greenhouse Direct Canada Ltd., then this would mean reading carefully through all directions before starting construction because no two models may look alike despite having similar functionality due to their form factors being custom-made based on specific needs such as whether or not they’re meant only indoors or outdoors usage only etcetera etcetera ad nauseam ad infinitum until death takes us away…

Add Lighting To Your Greenhouse

Your greenhouse is the perfect place to grow your own food, but without proper lighting, you’ll have a hard time seeing what you’re doing. 

It’s a good idea to install LED lights in your greenhouse to make it easy for you to work on your plants and get them in the right position for optimal growth. LED lights are also more energy efficient than other types of artificial light, so they’re better for the environment as well.

If you want natural light in addition to artificial light, consider building a skylight or opening up some windows on either side of your structure. 

This will provide sufficient ambient light while still letting in plenty of fresh air through an open door or window. You could even just hang up some curtains if natural sunlight isn’t important enough yet!

You may also want something more specialized like low-voltage fluorescent tube fixtures that come with their own ballasts (or power supplies). 

These can be used instead if desired depending on how much space there is available within each corner section when stacking multiple staging areas together vertically like this one does; however these are not required unless you plan on having overhead equipment hanging down from above at least 1 inch above each floor level.”

Heating a greenhouse efficiently is crucial for maintaining the ideal temperature for your plants. Find out how much propane you’ll need to heat your greenhouse and optimize energy consumption. Check our informative article on how much propane it takes to heat a greenhouse and ensure a warm and thriving environment for your plants.


So, now you know the basics of how to assemble a greenhouse. And if you’re feeling ambitious, there are plenty of other things you can do once your greenhouse is up and running. 

For example, you can add lighting or watering systems that make it easier on yourself when tending plants inside during cold months or dry spells. 

You may even want to consider adding shelves or benches so that visitors have somewhere comfortable while they enjoy the view!
