Finding a good greenhouse kit can be a bit tricky. To make the search process easier for you, here’s a brief overview of the 3 best 8×16 ft greenhouse kits that you can find out there:

1. Riverstone Industries Monticello (8 x 16 Ft) Black Greenhouse

Kicking off the list with one of our favorite greenhouse kits, the Monticello Black Greenhouse.

This one has a frame that is made of high-grade and heavy-duty extruded aluminum with an attractive electrostatic painting for added protection. However, you can choose between a black or aluminum finish to suit your garden style.

The walls are made of an 8-millimeter polycarbonate panel in a twin-wall design that boosts the insulation and durability of the greenhouse kit.

The 7.5 ft height allows for a large headroom inside the greenhouse and boosts the quality of heat displacement inside the kit.

Users absolutely loved the functionality and durability of the greenhouse. Yet, the room for improvement regarding this greenhouse kit is the assembly. The process might be a bit lengthy and requires some patience.

Things We Like

• Excellent design for headroom and heat displacement
• Available in two finishes
• The roof vents pull in a lot of air when opened 

Things We Didn’t Like

• Can be a bit tricky during assembly

2. Rion Grand Gardener 2 (8 x 16 Ft) Twin Wall Greenhouse

The Rion Grand Gardener 2 Greenhouse is another excellent choice for the 8×16 ft variety. It offers a sturdy resin frame in a dark-green color that balances between insulation and durability. Yet, Rion offers an option for clear walls if you don’t need the added insulation.

The walls of the greenhouse are made of double-wall polycarbonate panels, which are 4 and 6 mm thick. 

This thickness is great for UV rays protection and impact resistance, without being too heavy to deal with.

The greenhouse has a double door design, which is not only good for easy transport in and out of the greenhouse, but also for offering a great air cycle inside.

The greenhouse looks pretty lovely with the barn design, which is also very practical for heat displacement inside. 

Things We Like

• Heavy-duty construction makes it highly durable and stands the test of time
• Takes less time to assemble when compared to other options on the market
• The double doors are great for ventilation and ease of transport

Things We Didn’t Like

• A bit pricey

3. Palram Snap & Grow (8 x 16 Ft) Silver Greenhouse

Lastly, if you’re on a strict budget and looking for an 8×16 ft greenhouse solution, this one might pique your interest!

This one comes with a galvanized steel base, which offers an outstanding level of durability. Not only that, but we also loved that it comes with multiple upgrades that add more value to the package, such as the manual roof vents and the built-in rain gutters.

Another excellent bonus that makes this one a great value for money is the 5-year warranty included with the greenhouse!

Users loved the ease of assembly and the durability of the frame. However, the 1 mm polycarbonate panels might not be ideal for gardens grown in extremely windy weather.

Things We Like

• Ideal for buyers on a budget
• Features multiple accessories, such as rain gutters and roof vents
• Comes with a 5-year warranty for a worry-free purchase

Things We Didn’t Like

• The thin panels might warp in strong wind

How to Choose The Ideal Greenhouse Kit for Your Needs

While shopping for an 8×16 ft greenhouse kit, there are some aspects that you need to keep in mind to make the most out of your investment, so we’ve summed up these critical points in this section. Here’s what you need to know.

Durability

The durability of a greenhouse kit relies mainly on the construction of the frame, as well as the materials used in designing the exteriors.

Ideally, you should go for polycarbonate panels for the walls. Polycarbonate is quite translucent yet powerful against the wind and blocks UV rays nicely. The thicker the panels, the sturdier it’ll be against the strong wind.

The frame can be made of hard resin or aluminum. Choosing between those materials also depends on the strength of the wind in your area vs the ease of assembly. As a rule of thumb, resin construction is easier but not as durable against the wind as aluminum.

Insulation

Ideally, twin-wall polycarbonate panels will have a higher level of insulation than the regular one. Thicker polycarbonate panels will also have a better UV resistance.

However, twin walls are not as transparent and will cost significantly more. The choice here depends on the weather in the area you’re growing as well as your budget.

Ventilation 

A good greenhouse should balance between insulation and a decent room for ventilation. Always make sure that the greenhouse kit offers various windows, whether manual or automatic, as well as doors.

Wrap Up

There you have it. A complete guide with everything you need to know before deciding on the ideal 8×16 greenhouse for your gardening needs.

Ideally, we recommend the Riverstone Industries Monticello Greenhouse as the overall best option on the market. 

Despite being a bit tricky while putting it together, it comes with all the necessary features for a greenhouse kit, such as the heavy-duty extruded aluminum frame construction, the UV stable polycarbonate twin walls, and the highly adjustable vents and doors.However, if you’re on a budget, the Palram Snap & Grow Greenhouse would be a more suitable choice for you. It offers decent protection and insulation for a price that won’t put a dent in your wallet!
