im probably going to make it 3ft high 15x15 length and width. I was wondering what should i build it out of? if im going to make one, it has to be stealthy, so i need to disguise it as something that is usable. Like no one would think of opening it or it has a back door of a secret compartment? and ideas, plus its a pretty small area and i was going to get computer fans but what about the smell? pc fans cant fully use the carbon filter? how should i treat the smell. i have about 500$ should i just buy this http://www.unique-hydroponics.com/grow-cabinets/hydroponic-grow-boxes/led-version-easyryder-box/ or should i build
