Best Greenhouses for Colorado

Colorado has one of the most interesting and diverse climates in the United States. Unlike many other states, the general rule of thumb that the northern parts are colder than the southern ones isn’t necessarily true in Colorado.

But a good greenhouse can make it possible year-round. We’ve done the digging for you and found several of the best greenhouses for Colorado.

What to Consider When Buying a Greenhouse for Colorado

Temperature Stability

Your greenhouse needs to be stable inside because the weather and temperatures can vary so much based on which part of the state you’re in. Ideally, the greenhouse should form a consistent setting for your plants to grow in.

Insulation is a must in this regard. Some greenhouses will have frames designed to help with insulation or seals around doors and windows to keep cold or warm air.

Keeping it warm isn’t all you need to be concerned about. You also need to prepare for the possibility of your greenhouse getting too hot.

The easiest way to help prevent that possibility is by putting your greenhouse in a shady spot. However, having vents or even shade cloths can help even further.

Wind Rating

greenhouse wind rating

In some parts of Colorado, tornadoes and ferocious storms are other possibilities you’ll need to prepare for. This is why some greenhouses are rated for wind.

The higher the wind rating, the greater the wind speed your greenhouse can withstand. We specifically looked for greenhouses with a high wind rating for a lot of the greenhouses on this list.

But if you’re looking elsewhere, make sure you pay attention to the wind rating. Most of the time, you can find this in the product description.

Roof Weight Capacity

During colder months, snowstorms can happen in Colorado. This is particularly true if you live at a high altitude, where temperatures can freeze.

For that reason, many greenhouses will list how much snow their roof can hold. This can be an important quality to look at if it’s listed.

Otherwise, you can factor in the shape of the greenhouse. Like a couple on this list, Bell-shaped or arched greenhouses usually are not able to hold snow on top as it slides right down the sides.

Ease of Assembly

easy to assemble greenhouse

You probably don’t want to spend days just putting together your greenhouse once it arrives. More likely than not, you want to be able to use it as soon as possible, especially since it can be costly.

This is why it’s important to read about the assembly for each greenhouse. You’ll usually find a little information on this in the description.

One thing to look at is the tools that are required for assembly. If a greenhouse doesn’t need a lot of tools, it won’t be as complex to set up.

Another place to look, though, is at comments from other buyers. Most will mention if there was some difficulty putting the greenhouse together.

Wrap Up

If we had to choose one greenhouse for a Colorado gardener, we’d suggest the Riga Greenhouse. It has many design elements that give it the strength it needs for extreme weather.

Its bell shape prevents snow from piling on top. But even if snow were gathered on top of it, it can hold up to 180 pounds of snow.

The materials used to make it are resistant to UV rays, rot, and mildew. You can anticipate it to stand in your yard for years to come.
