Palram - Canopia | Bella Greenhouse 8 Ft Wide - Silver With 6mm Twin-wall Polycarbonate Glazing

Is this an all-weather greenhouse that can be used in the winter?

The Bella Greenhouse can be used year-round, however 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 the 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 Palram Glory Greenhouse which has a 10mm polycarbonate covering.

How does one secure the greenhouse to a foundation? Can the greenhouse be anchored to a concrete slab? Can it be anchored directly to the ground?

It can be anchored to a foundation, the Bella has designated anchoring holes at the bottom of the greenhouse base. Yes, the greenhouse can be anchored to concrete slab or a woden foundation using the appropriate fasterners (not included with the kit). 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.

How well will this hold up in a hailstorm? We have at least 3 hailstorms each year so I really need to know before purchase.

The polycarbonate panels have a high impact resistance and will withstand hail.

Does this greenhouse come with a floor or floor frame?

This green does not come with a floor or floor frame.

Can I get doors on both sides?

No, it is not an option to get doors on both ends.

Can this be disassembled to move it to another location, or is it a permanent structure once assembled?

Yes, it can be disassembled, relocated, and reassembled at a different location.

Can two greenhouses be put together to form a larger one?

No, this is not an option.

If I'm pouring a slab foundation, what are the dimensions needed?

You need at least 2 inches of slab protruding around the outside of the greenhouse base frame.  You can check the dimensional drawings to get the exact greenhouse dimensions in cm.  If you just add 2" to the nominal dimensions of the greenhouse that will give you 2-3 inches.

Nominal  Actual (cm)   Actual (ft. in.)
8x8 ft      244x244cm   8'x8'
8x12 ft    244x364cm   8'x11'11"
8x16 ft    244x484cm   8'x15'11"
8x20 ft    244x604cm   8'x19'10"

what is the anchor system? i live on lake and get high winds, what is wind rating?

For anchoring, the galvanized steel base included with the Palram - Canopia Bella greenhouse has designated holes for anchoring for additional structural stability (anchors not supplied).  Please take a look at the 'Foundation' section on the page linked below to see the manufacturer's suggested foundation and anchoring approaches.  The assembly manual will also have some details for you, and we are happy to send that to you as a pdf if you would like, please send a request to info@mygreenhousestore.com.

The bell-shaped Palram - Canopia Bella greenhouse was specifically designed to improve wind resistance and allow snow to easily slide off.  

The wind rating is 60 MPH.  You can also create your own 'hurricane straps' anchoring system yourself for heavy wind locations, however the manufacturer does not provide a cable/strap tie-down style anchoring system for this model.  They do for some other models, so if that is a criteria for you, please browse the site and look at some of the other models. If you have severe winds, the best practice would be to plan your greenhouse location to take advantage of either natural windbreaks such as a treeline, or a man-made windbreak such as a house or barn close to one side of the greenhouse.

The snow load rating is 20 lb/sq ft.  As with all installations in snowy locations, we have a few common-sense words of advice.  20 lb/sq ft represents about the *average* weight of 1 foot depth of snow.  Dry power is much lighter, and wet snow, ice, and accumulated packed snow can be much heavier.  The shape of the Palram - Canopia Bella greenhouse makes it easy to sweep and clear snow (if any even sticks to the sloped shape) on a daily basis during heavy snow season.  This is best, to avoid any accumulation.
