About Sungrow Automatic Roof Vent

Please note: this window only fits Sungrow Greenhouse models.

The Planta Sungrow Automatic Roof Vent is the perfect complement to your Sungrow Greenhouse. It will provide increased ventilation and enhance air circulation, both of which are essential for the healthy growth of plants.

The automatic opener is heat-activated and doesn’t require any electricity or programming. This feature guarantees that any hot air will escape throughout the day, preventing your plants from shrivelling up or wilting.

The amount of windows required depends on the greenhouse size, the climate you are in, and the types of plants that will be grown. However, as a general rule of thumb, the following numbers work well:

  • Sungrow Compact (10x6.5): 0-2 windows
  • Sungrow Urban (10x13): 2-4 windows
  • Sungrow 20 (10x20): 4-6 windows
  • Sungrow 26 (10x26): 6 windows
  • Sungrow 32 (10x32): 6-8 windows

We recommend installing an even number of roof vents on either side of the greenhouse for optimum airflow.

Technical data:

  • Size: 3 ft wide by 1.4 ft tall (91.4 cm by 42.6 cm)
  • Maximum window opening: approximately 45cm (17 23/32 in) depending on adjustment and load
  • Start opening temperature: 17 °C-25°C (62,60°F-77°F)
  • Maximum opening temperature: 30 °C (86°F)

      Automatic Roof Vents

      Easy to build but somewhat difficult to install. Most importantly both of mine are working great.

      Windows leak

      They work fine although one sticks part way open sometimes. All four windows leak when it rains. The weatherproofing system is hard to install and does not seal very well.
