I have a question about grow tents. Specificaly, the Home Box XS. If I used it to grow one, max two plants, would the ventilation provided w/ the box be enough? The idea is to put the whole box in a large closet, because cutting any kind of hole in the wall is not an option. I was planning to leave the closet door open during light hours, so that fresh air could enter through the boxes built in ventilation.
