Adequate Ventilation
 One of the most important aspects of greenhouse growing is having sufficient ventilation. Bayliss have designed their autovents take the guesswork out of this all important operation, ensuring accurate, continuous venting 24 hours a day. 
 This autovent works as it includes a strong metal tube that contains a mineral wax which expands with heat. This pushes a piston which opens the auto vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong stainless steel spring closes the vent and resets the piston.
