    Excellent choice!

    I ordered the sigma 32 model in April ‘23. Fast shipping and no problems with the freight delivery. It is now September and it has been a little summer project putting together. Received all of the hardware with no missing parts, and there are a lot of them. Comes with assembly instructions that seem overwhelming at first, but once you match up your parts it’s not bad. Definitely at least a 2 man job. I live in Illinois and I’m betting this will be warm in to December. It will be exciting to see just how many more months I can get out of the growing season. I still need to purchase the vents at a later time but I love this greenhouse! It is the best value for your money I could find. I look forward to many years of use. With the 5 year warranty, I think it will last 10 years or longer. Thank you for such an awesome experience!!

    So far so good! It's almost finished but not quite yet. It definitely takes time to put it together. I'm super happy with it and will probably be buying another one to add on to it next year. :)

    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)

    Buying from Planta was simple and efficient

    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 can't wait until we can buy a second greenhouse!

    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!

Residential Greenhouses

Are there doors on both ends of the greenhouse?

Yes! All of our Sungrow models come with manual doors and a manual window above the door on both ends of the greenhouse.

Do you have lean-to greenhouses?

Unfortunately, we do not have any lean-to greenhouses available at this time.

Do you make custom size greenhouses?

All of our products come pre-packaged by the manufacturer and can only be customized in length (2m extension). However, the height of the greenhouse can also be increased if placed on a base (up to 1.5m above the ground).

How is the greenhouse anchored to the ground?

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.

What is the frame made of?

The greenhouse frame is made out of heavy-duty galvanized steel.

What is the width of the door opening?

For our Sungrow models, the door opening width is 800mm.

What polycarbonate panels are used for residential greenhouses?

We use 6mm heavy-duty, double-walled polycarbonate panels with a UV-protected outside layer for our Residential Greenhouses.

What type of base/foundation is the best for me?

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.

FAQs Sigma ventilation window

Can I add windows for my greenhouse later?

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.

How many roof ventilation windows are recommended for the greenhouse?

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.

FAQs Sigma automatic ventilation window

How do the Automatic Ventilation Windows work?

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.

What are the opening and maximum opening temperatures for the Automatic Windows?

The opening temperature is between 17 °C and 25°C, while the maximum opening is at 30 °C.

Sigma Greenhouses

What are the snow load and wind resistance on the Sigma models?

Sigma models can hold a snow load weight of 160 kg / m2 or 91cm of fresh snow on top of the greenhouse. The wind resistance is 100km/h.

Additionally, you can learn more about it on our Greenhouse Bases blog.

Customization Options

Can I add my own vents, fans, heaters, and lights?

Of course! The polycarbonate is very easy to work with, and the galvanized steel frame is strong enough to support any additional accessories.

Can I get a longer greenhouse?

Most of our residential and commercial greenhouses are extendable up to 30 metres. Learn more about our extension kits for both the Sungrow and Sigma models.

How can I customize my greenhouse?

The customization possibilities are truly endless with a Planta Greenhouse. To help you get started, take a look through “16 Ways to Supercharge Your Greenhouse” on our blog.

Is hanging plants, heaters, and hammocks safe from my greenhouse frame? How much weight does it handle without affecting the guarantee?

It is safe to hang plants and accessories on a Sungrow greenhouse since each internal reinforcement arch can withstand up to 45.3 Kg. On the Sigma series, you can pre-drill the holes on the framing and hang small things. We would not suggest hanging anything heavier than 2.2 – 4.5 Kg per arch.

May I heat my greenhouse with firepits or similar?

You can use any heating source inside, like electricity, gas, propane, and even wood. It may be tricky to heat with wood, as you want to ensure that you keep the stove/pit away from the panels to prevent them from melting or burning if they are too close to the fire source. In this case, the customers ideally would want to come up with an exhaust system, making sure it’s not in contact with the panels, for being a flammable material.
