Picture a space in your own backyard that always feels perfect inside, no matter what the weather is like. A garden where gusty winds and icy snow can't affect even the most delicate of plants. A place bursting with new life year-round. A zen-like oasis where you can calmly start your day in the warmth and quiet.
Strong and spacious: long-lasting construction, weather-resistant materials, and roomy design.
Take backyard farming to the next level with the Planta Sigma 32. This greenhouse was designed with heavy-duty materials that promote 3 or 4 seasons of growing, allowing for multiple harvests every year. In addition, the innovative engineering and tough construction we use means you can harness the power of a commercial greenhouse in an attractive backyard design.

The rust-resistant galvanized pipe frame means your greenhouse will be standing for years to come. It's tough enough to withstand moderate to extreme weather conditions, allowing your garden to flourish wherever you may live.
The greenhouse comes with:
Stay comfortable and cool throughout the day thanks to the spacious design, tall 7ft roof height, and end-to-end ventilation.
We installed our greenhouse in 2021, & in our first year we grew tomatoes, cucumbers, green beans, strawberries, peppers, broccoli, and brussels sprouts. The greenhouse extended our growing season till mid October with minimal added heat latterly. Our favorite thing about having a greenhouse is the ready supply of fresh and healthy food, some of which we preserved and some gifted to friends and neighbors. Looking forward to next season.
Buying from Planta was simple and efficient. Everything arrived when scheduled and promised and follow up questions were promptly and courteously answered by Nick. We are really happy with our purchase even to the extent of adding a ten-foot extension in our first season. We can highly recommend Planta even here in the Alberta foothills with its strong chinook winds and frequent snow.
We have very strong Chinook winds in this area and our greenhouse has so far stood up very well despite a close neighbour losing a large tubular shelter to the wind a few weeks ago. We love the automatic windows and with those and our automatic drip irrigation, regular maintenance is minimal.
Another shout out to Nick for his friendly and prompt attention to our questions.
We installed our Planta Greenhouse in 2021 and we grow vegetables. It changed our growing season by making it much longer.
My experience buying from Planta was very good. Service and quality are excellent, installation manual could be better. Everything is tight fit. Perfect!
My favorite thing about the greenhouse is that it's been sturdy in all the storms we get, blocks the sun perfectly, and stops plants from burning. We can't wait until we can buy a second greenhouse. No more outdoor gardens for us here!
To someone considering buying a Planta Greenhouse – I think it’s the best thing we ever did. Don't hesitate or buy a cheap take-off. This is good quality at a reasonable price. Could be Dutch!
We installed our greenhouse in 2021 and started growing vegetables. The experience buying from Planta Greenhouses was excellent and the greenhouse itself was easy to build and well made. This greenhouse has changed our growing season by extending the fall season – we still haven’t had our spring season yet. To someone who is considering buying a Planta Greenhouse, I would say “you will enjoy it".
Good quality structural materials. Took longer than I had thought to assemble but otherwise good. I had to back track a few times with the assembly.
Some of the fittings/nut and bolts seem a bit flimsy so will be watching to see if they loosen off or break and am quite prepared to upsize them.
Would recommend the Sigma to anyone (that knows how to use tools and has had experience building things)

Planta Greenhouses is dedicated to deliver your order promptly, so you can begin using your greenhouse products right away.
Because greenhouses are packaged in large boxes, they have unique shipping requirements, including:
Every greenhouse kit comes with optional legs that can be dug directly into the ground. The amount of legs included depends on the greenhouse size.
Yes! All of our Sungrow models come with manual doors and a manual window above the door on both ends of the greenhouse.
For our Sungrow models, the door opening width is 800mm or 31.5".
There are several different types of greenhouse bases, information, and pictures posted by our customers on our Customer Stories page and our Planta Facebook page. Additionally, you can learn more about "Types of Greenhouse Bases - With Pros & Cons of Each" on our blog.
Unfortunately, we do not have any lean-to greenhouses available at this time.
All of our products come pre-packaged by the manufacturer and can only be customized in length (6.5' extension). However, the height of the greenhouse can also be increased if placed on a base (up to 5ft above the ground)
We use 6mm heavy-duty, double-walled polycarbonate panels with a UV-protected outside layer for our Residential Greenhouses.
The greenhouse frame is made out of heavy-duty galvanized steel.
It is strongly recommended to go with an even amount of roof ventilation windows. This is so you can place at least one on either side of the greenhouse. The amount of windows required depends on the greenhouse size, the climate you are in, and the types of plants that will be grown inside the greenhouse.
Our Automatic Ventilation Windows do not require any batteries or electricity. A heat-activated mechanism will open/close the window once a certain temperature is reached.
The opening temperature is between 17 °C and 25°C (62.6°F to 77°F), while the maximum opening is at 30 °C (86°F).
Roof ventilation windows work as an add-on and can be installed only once the greenhouse installation is complete. Windows can be added later as well.
Sigma models can hold a snow load weight of 32 psf (160 kg / m2) or 3ft of fresh snow on top of the greenhouse. The wind resistance is 65 mp/h (100km/h).
On our YouTube channel, you'll find step-by-step installation guide videos to help ease the installation process.
Of course! Our after-sales customer service team is available to answer any and every question. You can fill out our contact form or give us a call at 1 (877) 669-1286.
Absolutely! The polycarbonate is very easy to work with, and the galvanized steel frame is strong enough to support any additional accessories.
Our greenhouses are extendable up to 100ft. Learn more about our extension kits for both the Sungrow and Sigma models.
