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)

    Greenhouses are amazing products, and they require special shipping and handling. That is the reason, we have been working diligently over the past year to secure preferential shipping rates for our customers. Most shipments across Canada and the US are between $250 and $450. 

    • We will contact you to confirm shipping price, based on your location and order size.
    • Shipping on most residential greenhouse orders is between $250 and $450, customers in remote areas may need to pay extra.
    • When you place your order, please make sure to enter the correct Phone and Address at checkout. You will be contacted by phone before the item is shipped. We cannot be responsible for deliveries to incorrect addresses.
    • As part of the delivery process, we require a contactable telephone number (for the courier company to contact you) before the item is shipped.
    • White glove delivery service isn't available. The greenhouse components are delivered in multiple boxes, the largest of which weighs 80lbs. The greenhouse will be delivered to your driveway. Please make arrangements to have the package moved to its installation location. 
    • We do not ship to PO Boxes, as in most cases you will need to sign for your item.  
    • Orders placed on weekends or public holidays will not begin processing until the next business day.
