#1. Best Greenhouse: Palram HG5508PH Hybrid

The Palram Hybrid Greenhouse is the best of the list. With its sturdy frame and tightly-sealed panels, it is the perfect portable greenhouse for winter. This model features a rust-free and rust-resistant aluminum frame with nearly unbreakable polycarbonate wall and roof panels. The transparent wall panels allow 90% light transmission for healthy plant grown while the twin-wall 4mm-thick roof panels keep off as much as 99.9% of harmful UV rays. The thicker panels also help control the amount of sunlight coming in to prevent plant burns and encourage shade in certain areas of the greenhouse.

Solidly built, see-through, and roomy enough, the Palram Hybrid Greenhouse can work well as one of the best year round greenhouse kits. It has 48 sq. ft. of space for growing plants and features rain gutters and adjustable roof vent. There are 10 plant hangers made of polypropylene for air plants and vine crops. This model is secured by a magnetic door to regulate humidity and maintain the proper balance of heat and moisture inside.

Top Questions About the Product

A: This kit withstands heavy rains and most weather, and has proven to be leak-proof.

Q:  Is it a good all-weather, all-season greenhouse kit?
A: This is a basic kit and while it can withstand regular weather, it is best to reinforce the sides to prevent breakage or falling apart in very strong winds or heavy snow.

Top Q&A

Q: Is it easy to assemble?
A: Light enough for quick assembly by an individual. The instructions consist of a single page of line drawings that also doubles as a parts list. The seller will gladly email a more detailed instruction manual if requested.

Q: Is this a good, all-weather greenhouse kit?
A: The plastic cover, along with the insect netting, does not make this on the list of recommended portable greenhouse for winter. It will work well in locations that receive enough sunshine, though.

Q: Will it blow over?
A: This kit is portable, hence it is designed for easy assembly and disassembly. If you live in a location that experiences strong winds from time to time, consider reinforcing the base.

What’s Our Take on This Greenhouse Kit?

Portable and lightweight, this model works best for basic greenhouse planting needs and as a starter unit. The pipes will need some insulation if you live in an area that can get hot during the summer but otherwise, this is a great option that offers portability and ease-of-use.

#3. Rion Grand Gardener 2 Clear Greenhouse, 8′ x 16′

This roomy model is one of the best kits for gardeners who require more space. The 4mm-thick twin-wall polycarbonate roofing provides strong protection against UV light, filtering it completely. It is also almost unbreakable, thanks to its high-impact resistance.

The side panels are made with clear polycarbonate to allow sunlight to penetrate unobstructed. The frame is made with heavy duty resin that lasts long without requiring special care or treatment. In terms of design, this one is a lovely winner, its barn shape creating more headroom and more space for plants.

A: Properly assembled and secured, this model can withstand up to 55mph winds.

What is our take on this greenhouse kit?

The design and space are great features of this model, along with the clear panels for easy viewing. Assembly requires patience and focus because there are numerous parts to put together but the final product is worth it. It also comes with an extra base (at extra cost) to increase the height of the greenhouse.

#4. Flower House FHSP300CL SpringHouse Greenhouse

This portable greenhouse kit is a practical solution for gardeners who have a few special plants to care for. The set up is quick and easy and while the size is not impressive, it has enough room for several plants to grow.

This option features a canopy made from transparent PVC material treated for UV protection. Lightweight and easy to set up or take down, this is the perfect choice for backyards or apartments with limited spaces.

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. If you happen to live in areas that get cold nights, the types of plants you use this kit with should be the ones that could withstand lower temperatures. If you experience heavy snow, a more durable and weatherproof option may be better.

Q: Will it blow over?
A: In very strong winds, it probably will but may be secured with ties or heavy pots set on the flaps.

Q: Can it protect plants from heavy rains?
A: The plastic cover is waterproof. As long as there are no tears on the material, this little greenhouse can keep your plants from getting drenched.

What’s our take on this greenhouse kit?

This is probably the little greenhouse that could. Granted, it is meant as a flower house but it could be used to protect other plants as well. The space it offers is fairly limited but that should not discourage you from this option. It is the perfect choice for limited spaces and for housing plants with special needs.

#5. King Canopy GH1010 10-Feet by 10-Feet Fully Enclosed Greenhouse

This is one of the roomiest options on this list, measuring 126″ x 115″ x 95″. This walk-in kit features a fully enclosed and fitted plastic translucent cover over a white powder-coated steel frame. The plastic cover itself is treated by UV inhibitors, and is water resistant and fire retardant.

What’s our take on this greenhouse kit?

Perfect choice for a large backyard and for gardeners looking for a greenhouse with lots of room. Height-wise, there is enough space overhead to hang planters and with the right-sized plant stand on the sides, this greenhouse kit can hold a good number of plants. Anchoring this kit to boards can help keep the base even and protect it from strong winds. Overall a great choice for the price and a great substitute for more pricey glass greenhouse kits.

#6. Best Greenhouse Plastic: Flower House FHPH150 PlantHouse 5 Pop-Up Plant House

What’s our take on this greenhouse kit?

This is a great portable option that offers decent space and protection for most plants. It is a good choice for homes with limited space. The plastic material is reasonably durable and there is enough protection against excess moisture because this is waterproof. It will need to be anchored to protect it (and the plants) against strong winds.

#7. Best Flower Garden Greenhouse: Outsunny 9’L x 3’W x 3’H Portable kit

The Outsunny portable flower garden greenhouse provides a protected environment for plants that require special care. This is the best choice for its category. It is a convenient, lightweight, and affordable choice for gardening enthusiasts. It features three flaps that can be rolled up completely for easy access and to improve air circulation.

The flaps also serve as heat vents to help control the heat and humidity inside the greenhouse. This kit consists of a heavy duty steel frame, powder coated to prevent chipping, peeling, rust, and corrosion. The transparent PVC cover fits over the frame snugly, allowing sunlight in to nourish the plants.

.

Pros	Cons
Heavy duty frame that resists rust and chipping, and a transparent canopy that allows full view of plants Features a 3-opening design that significantly improves air circulation and allows faster dissipation of heat; doors attach to the top of the canopy to keep the greenhouse open Lightweight, easy to set up, and take down	The design is horizontal, which may require more space for limited backyards The open floor may allow excess moisture in during rains The short height may require lots of bending and squatting when caring for plants

Top Q&A

Q: Can this kit allow enough sunlight?
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: Will it blow over?
A: This is designed as a horizontal piece and should be low enough to avoid the brunt of strong winds. However, it may be best to anchor the kit to the ground to secure it and keep the plants safe.

Q: Is this a good year round greenhouse?
A: Remarkably, this model has worked well in areas where winter temperatures can drop to a few notches below zero. Heavy snow may make a heavy burden on the plastic cover, though, as well as prevent sunlight from reaching the plants. This works well for moderate weather, or even in cold weather provided there is enough sunshine to warm up the plants.

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.

Ultimate Buyer’s Guide To Green House Kits

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.
