The manual greenhouse ventilation hatch is a compact, practical, and easy-to-install solution that solves the problem of hot air accumulating at the top of your greenhouse.
To ventilate your greenhouse, simply install the hatch in the roof in just a few minutes. This ensures your plants receive a full flow of cool air.
The manual hatch is a convenient and practical solution for ventilating your greenhouse. When the greenhouse gets hot, simply lift the pre-installed hatch upward (without much effort) using the specially designed handle and lock it in the open position. In the evening, when the greenhouse has cooled down, close the hatch.
ADVANTAGES: * Long service life * UV-resistant * Wind-resistant * Snow-resistant * Easy to install * No special maintenance required * No need to remove for the winter * Can be integrated into any part of the greenhouse.
We recommend installing one ventilation valve for greenhouses every 2-3 meters.
