Our Sigma greenhouses are built to last, featuring a rounded design and creative construction that brings heavy-duty greenhouse engineering into your own backyard.

The end-to-end airflow, spacious size, and high 7ft roof height make this a comfortable place to garden throughout the day.
The greenhouse comes with:

- the option to install multiple windows.
The galvanized pipe frame is both rust-resistant and durable. In addition, the construction can withstand moderate to extreme weather conditions, ensuring your garden will stay safe and flourish throughout the seasons.
- KMKevin M.Verified BuyerRated 5 stars6 months agoThe stability of the greenhouse is really good even in the wind
We installed our greenhouse in 2021 and right now we are starting the new garden for 2022, so we’re growing seeds and other plans that can’t handle the cold. I believe it will add to the times we can grow. With the heater we bought with the greenhouse we should be able to grow year round. The stability of the greenhouse is really good even in the wind. And we had snow just this week (February) and it is holding up perfectly.
My buying experience from Planta was good. It was challenging but rewarding to work through the instructions and also follow online video instructions for putting the greenhouse together. I’d recommend using both the paper manuals and online step by step videos when putting it together. If possible, have more than one person to construct the greenhouse. I was able to do it by myself but I’m sure it took quite a bit longer.

I installed planta greenhouse in 2021 & I grow houseplants, tomatoes, and peppers. I will also be starting seeds. With a greenhouse, I will be able to start veggies early and keep growing some all year round. What I love most about my greenhouse is that it is always a sunny, warm place to hang out. I can have more outdoor plants without having to let them freeze or find a place in the house for them during the winter. This green house is very durable. It has already held up to our 80 mph winds in Kansas.
I am so happy to report it is standing up to our harsh Kansas weather very well!!

I installed my Planta Greenhouse from Dec 2021 to Jan 2022 and I grow seedlings and flowers. The greenhouse helped to get planting started earlier and end later in the seasons.
My experience buying from Planta was very good, no issues. The greenhouse itself has good engineering and design.
To someone considering buying a Planta Greenhouse, I would say – Planta has the best selection. Get your land level as soon as you can before starting and take your time putting it together.

We installed our Planta Greenhouse in 2021. I have been growing tomatoes, lettuce, gourds, pumpkins, and papaya. So far, it extended our growing season and helped keep plants safe in our heavy winds.
Our experience buying from Planta was easy, if anything was wrong or missing the customer service team looked after this right away.
To someone considering buying a Planta Greenhouse, I would say – Go bigger at the beginning. It’s much easier than expanding. The greenhouse was easy to build once you understood the instructions. Lastly, I recommend the windows that open with temperatures for sure.

We installed our Planta Greenhouse in 2021 and we grow everything. It changed our growing season because we can now grow April 1st to November 1st vs May 1st to Oct 1st. The best thing about our greenhouse has been how well-built it was made.
Our experience buying from Planta was easy and the people were helpful and very professional. To someone considering buying a Planta Greenhouse, we would say, “You’ll be more than satisfied.”
