Halls/Juliana Auto Opener

The Halls solar-powered autovent is an innovative accessory designed for greenhouse owners who want to maintain optimal ventilation conditions even when they are not physically present. Proper ventilation is crucial in a greenhouse setting as it helps regulate temperature, humidity, and air circulation, all of which are vital for plant health.

The autovent simply clamps on to the vent and greenhouse frame, making it easy to install or take off.

The autovent operates using solar energy, making it an eco-friendly solution that does not require any electrical wiring or batteries. This feature ensures that the vent can function independently, relying solely on sunlight to power its operation.

This is one of our most popular greenhouse accessories and we highly recommend them to all greenhouse owners.  The auto openers can be added to a greenhouse order, or ordered separately as a spare/accessory.  When added to a greenhouse order, they will be delivered with your greenhouse.
