    Sungrow 26 Review

    A very sturdy greenhouse. I built a base out of 6x6 treated timbers. That is a must. Instead of leveling the gound, I found it easier to level the base. It is fairly simple to construct once I learned to think like a Canadian and re-educate myself with the metric system. Box labeling and unpacking the pallet was my biggest hurdle. Box 1, 2, & 3 could be cleary marked as Box 1, 2 & 3. Instead of 1/3, 2/3, 3/3. If Box 1/3 is the first box you should open. Then Box 1/3 should be the last box placed on the pallet prior to shipping. In the end, the build was successful and the Garden Goddess is happy.

    Does the job, the assembly seems intimidating if you read all of the comments saying how hard it is. It isn’t difficult, take your time, follow the instructions, follow them some more, then assemble. Do not go into it with the expectation of finishing it in a day, you won’t. Take your time and before you know it you’ll have a pretty cool greenhouse built.

    A dream a long time in the making!

    We're having it built by a local contractor. We are so excited! When it's finished we hope to have an open greenhouse to show our friends and family. And I've already planted a box of lettuce to take out as soon-- and I mean AS SOON--as it's finished!

    Bon investissement

    J’adore ma serre, c’est un havre de paix. Par contre il y a possibilité de faire quelques améliorations. Les instructions sont difficiles à comprendre, heureusement qu’il y a les vidéos, mais il manque quelques gros plans pour expliquer mieux certaines étapes. Je n’ai pas fait appel à un entrepreneur pour les fondations (en raison des coûts et du temps d’attente qu’il aurai fallu) mais j’aurais aimé avoir des plans détaillés. Je voulais planter en pleine terre et je n’ai pas utilisé de lit surélevé pour ne pas perdre de hauteur et pour ne pas avoir à modifier la porte. Personnellement j’ai installé ma serre sur des 6x6 que j’ai simplement déposé sur des blocs de ciment que j’ai nivelé du mieux que j’ai pu. J’espère que mes fondations ne se déplaceront pas trop avec le gel et le dégel. Quelques vis sont rouillé après seulement 3 mois. Je regrette de ne pas avoir scellé les « channels » des panneaux en polycarbonate avec du silicone plutôt qu’avec le ruban adhésif, car il y a un peu de condensation qui se forme. Ma serre est exposée plein soleil, la température devient très haute le jour donc j’ai installé un sunshade. Il serait bien que planta greenhouse offre des sunshade adapté à la grandeur des modèles. Bien que j’avais commandé les fenêtres, je ne les ai pas installées en car je veux limiter les infiltrations d’eau et les prêtes de chaleur. Concernant l’isolation, dès que le Soleil se couche, la température de la serre dessert rapidement pour atteindre la température…

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 Sungrow 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 Sungrow 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.

Sungrow Greenhouses

What is the snow load on the Sungrow models?

The Sungrow models can support a snow load of up to 183cm of fresh snow (360 kg / m2) on top of the greenhouse.

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.
