When setting up an indoor medical marijuana grow room, making sure you can bring fresh air in and exhaust old air out for air ventilation is very important. The quality of air and Co2 inside your grow room plays a major role in the quality of plant life, as this is what the plant needs to grow. There are 3 major things to remember when setting up an indoor room – air ventilation, stomata and air circulation.

Air Movement and Circulation

Indoor marijuana growing can be very easy if you have the proper air ventilation and circulation, especially the ability to bring fresh air into the grow room. You will need at least one fan for circulation and another for exhaust. Most growers today use a large charcoal filter can fan for their exhaust fan as it not only gets rid of the old air but also scrubs or cleans it, removing the smell from the air prior to exhausting outdoors.

How Plant Stomata uses Air

Stomata are the microscopic pores on the undersides of the leaf that regulate the flow of oxygen and carbon dioxide. The bigger the plant, the more stomata it has to bring in carbon dioxide and release oxygen. The larger the grow room and the more plants you have, the more fresh Co2 enriched air they will need to grow fast. Keep in mind that sprays that leave filmy residues will cause the stomata pores to clog, so always make sure to spray the plants with tepid (hot water mix with cold water) water 2 days after you spray them with any kind of pesticide or miticide spray to help open the pores up.

Grow Room Air Ventilation

Air Ventilation inside your cannabis grow room is as important as water and light are to your plants growth. All marijuana grow rooms need air ventilation, which can be accomplished using a window opening or a door opening to exhaust the air out. Use a squirrel fan or in-line blower to create the air movement or to bring new fresh air into the grow room.
