Greenhouses have moved out of commercial growers and into residential backyards. Plastic and glass greenhouse kits, along with pop up greenhouse kits have increased in popularity, thanks in large part to gardeners who prefer to take control of growing seasons and raise healthy, beautiful plants. If you are looking for a greenhouse for your backyard, learn more about how to find them, where, and what to look for.
Where to Find the Best Greenhouse Kits
The best options can be found online, particularly if you are looking for specific models, such as winter greenhouse kits, year round greenhouse kits, or pop up greenhouse kits. Many sellers and manufacturers offer good options online with great discounts. Greenhouse reviews are also excellent sources of information about greenhouse sizes, designs, and materials. Greenhouse reviews provide important details seen from the perspectives of users, allowing gardeners and homeowners to make an informed decision prior to purchase.
How to Choose the Best Greenhouse Kits
The best options are those made by reputable companies who can assure you of the high quality of materials and standards of manufacturing expected of these kits. Greenhouse kits must also be made from sturdy, reliable materials that can reasonably withstand the elements and carry sufficient load. Kits must also have the right size and design for your specific needs, particularly if you have certain types of plants you want to raise.
Choosing the Right Size
The perfect dimensions of a greenhouse will depend largely on two things: the types of plants that will be grown and the size of the area where the greenhouse will be built. A good starter greenhouse must be high enough to allow you to walk in and work comfortably. Even a portable, compact greenhouse kit should have sufficient width, height, and depth to accommodate the gardener, plants, pots, tools, and other necessities. If space is an issue, a small, portable lean-to should suffice.
What’s a Good Price?
Obviously, the larger and roomier a greenhouse kit is, the higher its price tag. However, it is a good idea to know the average price on certain options. Starter greenhouses, for example, will start at a little over $200 for a 6’x6′ or a 6’x8′. Larger models, on the other hand, can go over $500 and into the four-digit figures, particularly if it will accommodate features such as electronics and plumbing.
Location and Lighting
The location of the greenhouse should be carefully considered to maximize or control the amount of sun/shade that the plants will receive. The type of plants, along with your growing preferences, will also determine the best location for the greenhouse. Year-round growing, for example, is best supported by a greenhouse with a roof that runs east to west. If planting will be done in the spring and the summer, the best position would be a greenhouse that runs north to south.
In terms of lighting, there are always options. Natural lighting is best, particularly if the greenhouse will receive unobstructed light from the sun. If this is not possible, there are artificial greenhouse lights that can be installed to help support the growth of plants and provide much-needed heat, particularly during the cold months.
Climate and Insulation Material
Climate is another key factor to consider in choosing the right greenhouse kit. If your area experiences snow and ice during the winter months, for example, it is necessary to install proper insulation to protect the plants, conserve heat, regulate the temperature inside the greenhouse, and allow the plants to grow. In areas that receive heavy snow, it is necessary to choose winter greenhouse kits that are designed to withstand snow buildup. If the greenhouse is not built for carrying the load, the roof might collapse.

Top Q&A
Q: Can I use this year round?
A: The built and materials may not be enough to provide protection for the plants during winter months, particularly in very cold weather. It will work great for moderate weather, though.

A: The plastic cover is transparent and is quite efficient at letting in much-needed light at daytime.
Q: Is it durable?
A: This flower garden greenhouse features a durable plastic cover which should be able to withstand regular use. It is good enough for extending the seasons and giving the plants the chance to grow and flourish.

Q: Is this a good year round greenhouse?

What’s our take on this greenhouse kit?
This greenhouse kit is quite good for the price in terms of quality, design, and dimensions. Zippers are decent enough and would require some care when opening and closing the flaps if you want them to last. Assembly is fairly easy and the greenhouse is portable enough to be assembled, taken down, and moved elsewhere quite easily. It will need anchoring (using bricks or potted plants) but it can offer reasonable protection for plants.
