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.
