The Harmony greenhouse kit is a beautiful entry into the world of hobby gardening.

The greenhouse wall and roof panels are made of a nearly unbreakable polymer called polycarbonate that has the light transmission benefits of glass, but is lighter, stronger, and safer. The crystal-clear single panel roof and walls protect your plants from UV rays while providing all the full, direct light they need to thrive. This is especially ideal for germinating seeds and starting plants to heat up the soil and encourage germination.

The hobby greenhouse frame is made of rust-resistant aluminum mounted on a heavy-duty galvanized steel base for ultra-durable structural support. Other features include an integrated rain gutter to disperse the rainwater, a roof vent, and a lockable hinged door with a magnetic catch to help control temperature and humidity. The unique sliding panel system creates better insulation, stronger resistance to wind, and makes it easier to assemble than other DIY Greenhouses.

With this backyard greenhouse, you can prolong your growing season by starting in the early spring and extending your plant growth beyond the first fall frost. With its easy assembly, durable materials, and effective features, the Harmony greenhouse is the natural choice.

  • Highly resistant, fully transparent, and safe polycarbonate greenhouse (with Fine Shield Technology™)

    Ok I'll give it a try

    Satisfied with the greenhouse. It’s sturdy and the plants are thriving, thanks to the excellent light transmission. However, I did have to buy extra anchors for stability. It's good, but be prepared for some additional setup costs.

    Decent look and look professional

    The Harmony Greenhouse is decent. It looks nice in the garden and the plants are doing well so far. The assembly system is convenient, though I found the instructions could be clearer. A good buy, but there's room for improvement

    Worth Every Penny

    Was hemming and hawing over the Harmony greenhouse, but dang, it's worth every cent. The build is top-notch, and it looks slick in my yard. It's got this vent window that's clutch for airflow. My garden's never been happier. Best impulse buy I've made in ages


No, it is not an option, it cannot be performed.
Yes, it can be disassembled, relocated and reassembled at a different location.
No, it is not an option to get doors on both ends.
It is not possible to install the Lean To Grow House’ door at the other side. It is possible to install only as shown in the instructions.
The greenhouses do not come with a floor or base.
Yes, the polycarbonate panels are high impact resistant and withstand hail.
The warranty for all our greenhouses is for at least 5 years, some for more. The crystal-clear single layer or twin-wall polycarbonate panels maintain their integrity, they do not discolor, opacify, fracture or shatter over time.
Each wall section can carry up to 44 lbs. at most – an entire wall would depend upon the greenhouse’ size.
It can be anchored to a foundation, depending on the greenhouse, some have compatible holes at the bottom of the greenhouse base, and some have their own integrated anchoring. Yes, the greenhouse can be anchored to concrete slab. It can be anchored directly to the ground using ground stakes (ground stakes are not supplied with the greenhouse kits). *Firmly connect the product to a level surface immediately after completion of the assembly. Anchoring this product to the ground is essential to its stability and rigidity. It is required to complete this stage in order for your warranty to be valid.
The Canopia Greenhouse can be used year-round, but there are several factors to consider. The two main factors are weather and plants. What are the plants you want to grow and how much heat or cold can they handle? No matter where you live, greenhouses can be 20-40 degrees hotter inside during the day and at night they will be the same temperature as the outdoors. This is without any supplemental heating or cooling. Depending on where you live, heating and / or cooling your greenhouse can make a difference. If you need to heat or cool your greenhouse in extreme weather conditions, you may want to consider a twin-wall greenhouse such as the Canopia Glory Greenhouse which has a 10mm polycarbonate covering.
