Please note: this window only fits Sigma Greenhouse models.

Supercharge your Sigma Greenhouse with the Planta Sigma Automatic Ventilation Window. Improve air circulation by bringing in the fresh outside breeze, keeping your plants healthy and disease-free.

The automatic ventilation window is heat-activated, which requires no electrical power or programming. This function ensures that hot air escapes during the day, preventing shrivelling or withering of your plants.

The number of windows recommended depends on the size of the greenhouse, the environment you’re located, and the types of plants that you’re planning on growing. The following numbers, however, are good a starting point:

  • Sigma Urban (10x13): 2-4 windows
  • Sigma 20 (10x19.5): 4-6 windows
  • Sigma 26 (10x26): 6 windows
  • Sigma 32 (10x32): 6-8 windows

We recommend installing an even number of ventilation windows 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)

      If you are, read no further. For we mortals, however, I strongly suggest installing the frame before installing any polycarbonate panels. It was not possible for this elderly man to lift the poly, squeeze the pieces together to line up three holes and install a screw and nut. I ended up loosening the metal bands and removing the lower panel. As much as I love undoing and redoing my work, maybe a notification in the install manual for the greenhouse could have saved me a few hours.
