Ventilation of air and the supply of fresh air is sadly one of the most overlooked factors when creating a grow room. Air circulation and ventilation are absolutely definitive factors for happy plants and great yields. Without the availability of fresh air, the stomata become restricted and so does the plants’ potential.

As with humans, plants need oxygen to survive. In fact, cell for cell compared to humans, plants use very similar amounts of oxygen. So, in effect, plants need and use lots of oxygen. It has been found that a dried plant will consist of approximately 45% of oxygen atoms. So in conditions where the air has become stagnated inside a grow room and where the air has less than 20% oxygen, plants struggle to perform.
