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)
