One common thread between indoor and light dep greenhouse growers is the need to move high volumes of air through a space without the transfer of light. Use of homemade baffles, crisscross or “S” shaped ducting or piping underground have all been popular methods for preventing light penetration while moving air in or out of the grow space; although these methods are not always as effective as we’d like them to be. Typically, these techniques can restrict air and cause less efficiency in the air exchange.
Indoor growers have the same photoperiod criteria as light dep greenhouse growers: both still need to move air through a dark grow space without letting in light. Indoor growers use the Breathable Walls to exchange air from the outside in, or from light zone to light zone while using one air system. The Breathable Wall has less than a 5% airflow restriction that allows one to move air faster and more efficiently.
In the greenhouse setting, exhaust fans and intake shutters facilitate the movement of air and the transfer of light. The ultimate objective is to keep the fans on to exhaust air while the curtains remain closed during blackout times. With the Breathable Wall, this goal is achieved. Breathable Walls can be incorporated into retrofits, modifications, as well as new greenhouse construction.
With various sizes and configurations, we can cover almost any fan or shutter to fulfill total darkness and still maintain full air exchanges. The air flow helps support lower humidity levels and increases the amount of fresh oxygen given to the plants during blackout when the curtains are closed. With the assistance of the Breathable Walls in light dep and indoor applications, we promote better plant health due to increased airflow, which reduces pest and disease outbreaks.
