Choosing the Right Greenhouse Kits

Whether you are a novice gardener or a professional with a green thumb, purchasing a greenhouse is a great investment to enjoy gardening all year round. To get the most out of your time and money, there are several factors to consider before buying the best greenhouse kit that works for you.


The first thing to consider is how much space you are going to need for growing. Consider the cost relative to the size of the greenhouse. Generally, if you are just getting your feet wet in gardening, perhaps a starter kit is all you need.

The price directly affects your spending on the greenhouse. If you are going to start planting small, then it doesn’t make sense to buy a large greenhouse.

Keep in mind the type of plants you plan to grow and how much space they take up. You want to have enough workspace for you and the plants. The shape of a greenhouse will determine how much you can fit into it. Vegetables need plenty of headroom and a great deal of light and having a tall greenhouse will work to your advantage.


The price and size of the greenhouse go hand in hand. The bigger the kit, the more expensive it is. It’s smart to do a quick cost comparison relative to the size because typically, a taller greenhouse kits can be more budget friendly because they provide more room as compared to the standard kit with low overhead space.

The long-term investment can pay off if you grow your own produce.

Are there additional materials that need to be purchased that doesn’t come with the kit? How much maintenance will I need to put in order for the pay off to be worth it? Is the current condition of the land where the greenhouse is going to sit cleared and leveled?

If not, are you able to take the time to do it yourself or will you fork out the cash to have someone else do the work? Does your budget allow for accessories like ventilation and heating? How expensive is it to heat a greenhouse in extremely cold winters?


Another factor to think about is the strength of solar light your plants get from the sun. Determining the glaze of the panels needs to be considered. Should you choose clear, semi-opaque, or opaque paneling?

Each glaze offers different light strength. Deciding on the panel choice is determined by how you are growing plants. Starting with seedlings or growing plants to maturity need different strengths of diffused light.

Considering your lighting and insulation needs will help you grow a successful garden. These are important factors to not skip over and you don’t want to have a disappointing first year of gardening if you didn’t do the proper preparations.

Climate and Insulation Material

What is the climate in the area that you live in? If snow and ice are typical of the winter months and you want to grow plants year round, proper insulation is necessary for conserving heat. It’s also important to note that snow buildup on your covering can cause the roof to collapse.

Make sure to choose a sturdy and durable covering that can withstand harsh conditions. When the colder months are generally warmer, having a snow-proof covering is not necessary. It might do more harm than good to the plants.

Tempered glass panels or single-walled polycarbonate may be all that you need. Consider purchasing a greenhouse kit that will have the right insulation materials that suit your climate conditions.

Landscape Layout

The ideal location to place your greenhouse is an area that gets good sunlight. A good tip to use is to note the sun pattern over a few days to get a general idea of where the light hits before putting the kit together. Make sure that the greenhouse is going to be far away from structures that cast any unwanted shading.

Before making your purchase, make sure to check with local zoning regulations. There may be certain permits or restrictions on the size or type of the greenhouse.

In addition, ensure that you have prepped the site before installing the kit: Level the site and providing a good drainage material is important for long-term stability of your greenhouse. If you have little building experience, consider going the hassle free route by hiring a professional.
