Marijuana grow room ventilation


A question from a fellow grower:

is ventilation beyond a couple open windows adequate for good growth?


Well, a couple of open windows will give your inside girls the same air that the outside everything utilizes. So - it is adequate to produce some amount of weed. If you are interested in maximizing you output per plant/per grow, you might want to think about CO 2 enrichment. FYI - I grew in basements for years with little ventilation, and got reasonable results.


For good ventilation; You need an inlet with cool air to replace stale hot air.

Better off getting a window AC. It will allow you to keep temps perfect, and it will recirculate the air in the room. Peace
