Ventilation Fans

VLF-6-s2Ventilation is of the utmost importance when it comes to indoor growing or indoor operations. Fresh air and correct oxygen and carbon dioxide levels can mean the difference between healthy plant growth and stunted growing. Temperature control is also important when using hot grow lights or electronic equipment.

Ventilation equipment such as centrifugal fans and ductwork can make all the difference. These fans move high volumes of air in a highly efficient way. Replicating natural growing conditions is the goal and using proper ventilation, along with lighting and soil, can give plants the ideal conditions for growth.
