Ventilation is in the top 3 most important variables when growing. You can't just "open a door" or "put a fan on em".. You need an intake and an exhaust. Put the intake low to the ground and the exhaust near the ceiling. Tip: some crafty stoners like to run their exhaust "pipes" (too high to think of the correct word) out through their laundry dryer's exhaust so it just smells like laundry Oh and if you don't feel like cutting holes in your walls for ventilation (the professional way) you can put BIG fan in your doorway, and a fan in your window, but this is really a jerry-rigged way to do it. Regardless of how you do it, the key is airflow!
