Plant Inn mini-greenhouse serves as a fantastic alternative to a full-sized greenhouse in small backyards, balconies, and patios.

The peak is 58.3 inches high and has two lids for easy access as well as for temperature and humidity control.

    Took Some Effort, But Stands Well

    The instructions for assembly felt like they were written in a different language. However, after deciphering them and setting it up, I'm pleased with how solid the structure is.

    Looks great and I recommend this product!

    This greenhouse is really nice for beginners.

    My boyfriend set it up in just a couple hours. It’s nice, small enough to fit where we want it but big enough to grow exactly what we like. It’s perfect for what we’re using it for. Only word word of caution- the corners on the windows are sharp metal. No issues if it’s just you, but if you have...


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.
