Vents & Vent OpenersKeep your greenhouse breathing with the proper selection of vents and vent openers.
The proper type of ventilation is a must to keep your greenhouse from over-heating. Whether you’re growing in a hot house or a cold house, your greenhouse needs ventilation. We have a selection of passive ventilation options for your needs.
The standard Bayliss opener has an adjustable operating temperature between 55 & 75F (13-18C). Upgrades are available with the Orchid Wax for hot-house environments, and the Hydraulicheck opener for high wind areas up to 90 MPH gusts. Replacement cylinders are available for purchase with a one year warranty.
