I have grown indoors before now I am starting a medical cultivation center. The vegetative and flowering rooms both are 30’ x 30’ . my main concern is setting up a good ventilation system. My plan is to maintain 100 plants in both rooms. Lighting is 10 1000watt hps. Lamps . I would appreciate recommendations. Thank you for your time and help
For ventilation; You take the cubic feet of the room, and divide it bu the size fan or fans you use, to determine how many minutes it will take to replenish the room with fresh cool air. This determines how big of a fan or fans, that you use.
