a second grow room
For example, a second story grow room starting by cannabis seeds in a well-insulated two story house can use air from an intake vent that draws air from the living room below, especially if the house is in a hot climate. The air in the living room may be 10 - 15 degrees cooler than the outside air during the day. The downstairs air is also much cooler than the upstairs air. Everybody should know this,but if not, now you have no excuses about the cannabis seeds.
