Get your parents permission or wait until you have your own place. According to you, you have done your homework and know that it is cool. But your asking about smell, the smell alone is enough to get you busted. I am not even going to lead you in the right direction on how to control the smell. The simple answer is this; DO NOT GROW IN YOUR PARENTS HOUSE WITHOUT THEIR PERMISSION!!!! No if ands or buts, dont do it! If you were my kid and doing it behind my back, I would let you do the work, and then I would be a day or two ahead of you and confiscate your whole damn crop and keep it for myself. Dont ever think your parents dont know, we are smarter than you think we are, we just sometimes just do not reveal our knowledge when you think we should. Which makes us smarter than you. Dont do it.
