The system can ventilate when it is cold outside but warmed inside by lights and or the sun. This can be particularly effective for keeping the humidity under control and air exchanges happening to maintain proper crop climates.
Further advantages that reduced costs and/or enhance conditions include
*As there is much more controlled air exchanges, CO2 can be used more sparingly to maintain lower levels or raised easily to higher levels
*Pressurized greenhouse environment is much easier to control pests as air is always blowing out when doors are opened to outside or other non-pressurized areas
*The climate is more homogeneous due to less outside influences such as wind and the ability to exchange air under rainy conditions due to not requiring open vents during rain and windy periods
*As the greenhouse can operate with only 4% of the vents required in traditional greenhouses light transmission can be enhanced by as much as 15% in locations requiring insect screens.
