Can anyone help me out and give me some details. I am new to indoor growing and would like to use a hydro system for a vertical grow as to conserve space. I want to do a grow like his Heathes Ghetto Grow . I can build the box myself and will most likely be building a hollow box so no light or plants will be viable at all plus where i plan on putting the box does not have the best air quality, so i was wondering if i seal the box off and have ventilation just into the box and out of that box if that will help keep outt any molds or mildew
