Keep your plants cool and healthy during the hot and humid summer months with our Sigma automatic ventilation windows. The heat-activated opening feature allows you to easily maintain an ideal temperature inside your Sigma Greenhouse throughout the seasons.
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.

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