Best Greenhouse for Canadian Winter

Here are some of the best greenhouses for cold climates for you:

  • Climapod 9’x14′ Greenhouse, 6MM Virtue Complete KIT (Twin-Wall Polycarbonate, All Aluminum Heavy Duty Frame with Vents and Sliding Doors).

Built with thick aluminum profiles for framing and 6 MM polycarbonate panels, this greenhouse is built for cold climates.

It can handle both snow, rain, and the sun. It helps keep your plants and panels safe from UV rays.

No matter the amount of snow, or rain you face, this greenhouse is both durable and weatherproof. The roof is thick enough and is held firmly in place to withstand cold temperatures, and up to 15” inches of snow (It is recommended to remove snow loads over 12”).

Being very sturdy does come at a price – it is expensive and needs 1-3 people and 24-48 hours to fully assemble this unit.

The kit comes with tools that ensure a successful installation.

The warranty is 10 years. That means if you notice any damage upon arrival, you can contact them and they’d discuss how they can make your experience a better one.

What is included in this kit?

  • 6 MM UV Coated twin-wall Polycarbonate Panels
  • 5” Aluminum Base, 4 Roof Windows, and
  • 4 Manual Window Openers
  • 4 Automatic Window Openers
  • a Louver
  • 2 Solar Powered Thermostatic Fans, and a Full Size 2-Tier Aluminum Shelving (top & bottom shelves, for one side only).

  • Palram Hybrid Lean-to Greenhouse – 4′ x 8′

This greenhouse is nice but assembling it can be a pain in the butt. THIS greenhouse is lightweight yet sturdy for even areas with wind going 50-60 miles per hour.

Luckily for you we have done the hard part for you and you can do the following for a smooth installation experience:

Follow step 1-5 but remember to square or plum the base and drill anchor holes and bolt down as you will not have access at the end.

Plus, it will secure the vertical structure (8552 & 8540) that attaches to the house (without doing this, there’s no way to hold in place when you start step 6.

After that, skip step 7 and jump to step 9 then head over to 13/14  (including parts of step 7 where you slide in the side sheeting) then move to step 10 (again including parts of step 7); this will support the two sides while you install the wall in step 7. This is where you need someone to help support the wall while you install the sheets. Most of the rest of the instructions are okay…

Good luck!

  • Palram Nature Series Mythos Hobby Greenhouse – 6 x 8 x 7 Silver

Once up, this unit is quite secure than it looks. It withstands strong winds and the plastic panels will bounce hail off without any harm.

This greenhouse does not come with any tables or staging, but that’s fairly cheap, so you can add it yourself.

There is no flooring included, so you will need to figure something out.

For increased sturdiness, add custom built benches, screw everything down, and stake it down with steel cables. Way nicer and sturdier now.

To keep the windows from rattling and possibly coming loose in a thunderstorm you should duct tape the perimeters of each twin wall panel, both inside and outside.

Not only does it act as a caulking(waterproofing it), it is also very quiet now. When it pours the rain, the greenhouse does not leak.

I warn you that it will take two, possibly three people to assemble this greenhouse.

  • Outsunny 6’x8’x7.4’ Heavy-Duty Walk-in Greenhouse Outdoor Vegetable Plants Growing Warm House Seed Plant Growth Tent Polytunnel Shelter White

This green house is 100% excellent. The metal is strong and the screws hold it together quite nicely.


The plastic parts will not break from exposure. The size is very good for a city back yard and I think the cover will last a good 5 years at a minimum.

It withstands winds great and can handle the snow too. It’s been windy for 3 days here and this greenhouse didn’t even bulge.

  • MARS HYDRO Grow Tent 4’x8′ 1680D Canvas Reflective Mylar Grow Tents with Removable Floor Tray for Indoor Hydroponic Plant Growing Room 48”x96”x80” for 4xSP3000/2xTS3000

Once ordered, shipment is quite fast. You will receive your item in a discreet package as well.


The instructions are easy to follow and even without reading them, assembling this unit is very easy and straight forward.

App parts are labeled directly and identified on the plan. However, you would still be able to assemble it even without a plan – it’ll be easy to figure out.

All its frame and corners are metal. The canvas are good quality too, and the zippers work quite well without having to force anything, recognizing that the tent is new, but at the same time they feel good and not cheaply made.

The vents, door, and windows have double seals to close all the vents. I also like the full zip around the base to encourage setting up/down the tent.
