Air extraction is essential for creating an ideal climate for your plants in the growing area.

Plants need CO² for their metabolism. In insufficiently vented rooms, the plants consume the CO² present in just a
short time. If this is not replenished, metabolism will come to a virtual standstill. Proper ventilation results in a better growth process.

Each day growers take litres of water into the growing area. If there is not enough ventilation, the air humidity will rapidly become more than 80%. This is conducive to fungus growth, which can cause serious problems at the final
flowering stage. Therefore, you should keep air humidity at between 40% and 60%.

The presence of lamps in the growing area may cause the temperatures to rise to over 30°C. Such temperatures are harmful. Proper ventilation insures that the daily temperature will be about 25°C.

Warm air rises, cold air falls. Circulation is essential for a good air mixture. Moreover, proper circulation ensures a better CO² absorption by the plants. Stationary air around the leaves rapidly looses its CO² content to the plants.
Inadequate ventilation slows down the growing process. In addition, proper ventilation, together with proper humidity, prevents fungus growth and the movement of the plants ensures stronger stems.
