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.
Exact size: 118.1 x 83.9 x 394.49 inches
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)
