      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.

      Bon investissement

      J’adore ma serre, c’est un havre de paix. Par contre il y a possibilitĂ© de faire quelques amĂ©liorations. Les instructions sont difficiles Ă  comprendre, heureusement qu’il y a les vidĂ©os, mais il manque quelques gros plans pour expliquer mieux certaines Ă©tapes. Je n’ai pas fait appel Ă  un entrepreneur pour les fondations (en raison des coĂ»ts et du temps d’attente qu’il aurai fallu) mais j’aurais aimĂ© avoir des plans dĂ©taillĂ©s. Je voulais planter en pleine terre et je n’ai pas utilisĂ© de lit surĂ©levĂ© pour ne pas perdre de hauteur et pour ne pas avoir Ă  modifier la porte. Personnellement j’ai installĂ© ma serre sur des 6x6 que j’ai simplement dĂ©posĂ© sur des blocs de ciment que j’ai nivelĂ© du mieux que j’ai pu. J’espĂšre que mes fondations ne se dĂ©placeront pas trop avec le gel et le dĂ©gel. Quelques vis sont rouillĂ© aprĂšs seulement 3 mois. Je regrette de ne pas avoir scellĂ© les « channels Â» des panneaux en polycarbonate avec du silicone plutĂŽt qu’avec le ruban adhĂ©sif, car il y a un peu de condensation qui se forme. Ma serre est exposĂ©e plein soleil, la tempĂ©rature devient trĂšs haute le jour donc j’ai installĂ© un sunshade. Il serait bien que planta greenhouse offre des sunshade adaptĂ© Ă  la grandeur des modĂšles. Bien que j’avais commandĂ© les fenĂȘtres, je ne les ai pas installĂ©es en car je veux limiter les infiltrations d’eau et les prĂȘtes de chaleur. Concernant l’isolation, dĂšs que le Soleil se couche, la tempĂ©rature de la serre dessert rapidement pour atteindre la tempĂ©rature

      Sungrow 26

      I’m loving my Sungrow 26. Didn’t get the plants in the ground until July 11 so I’m just starting to pick zucchini and beans and tomatoes now. Figuring that with the plants being in a greenhouse, the season will be extended enough to get lots. Also looking forward to planting a fall garden. Using raised beds and square foot gardening.😊

    Residential Greenhouses

    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.

    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.

    What is the width of the door opening?

    For our Sungrow models, the door opening width is 800mm or 31.5".

    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.

    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 (6.5' extension). However, the height of the greenhouse can also be increased if placed on a base (up to 5ft above the ground)

    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 is the frame made of?

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

    Roof Ventilation Windows

    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.

    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 (62.6°F to 77°F), while the maximum opening is at 30 °C (86°F).

    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.

    Sungrow Greenhouses

    What is the snow load on the Sungrow models?

    The Sungrow models can hold snow load weight of up to 6ft of fresh snow (75 psf or 360 kg / m2) on top of the greenhouse.

    What is the wind resistance on the Sungrow models?

    The wind resistance is 100km/h (65 mp/h).
