• The only concern is 1: smell, and I am growing a very small amount maybe 4-6 OZ a month if I am lucky, so maybe 8-12 OZ each harvest, and I think that is a dream in a 5X5, but anyway my point is I am hoping it will not put out any smell with the carbon filter and negative air air flow, if needed I will go with a larger filer than needed to assure that, because smell is a major issue.
