i don't think you should have light on your germinating plants

can you lock the cab?

what happens when someone does come down there to the cab?

what about odor?

i'd guess that you probably won't be able to get away with it without anyone knowing, but i guess it's up to you

would your fam be very much against it? keep in mind that you could easily get them in trouble if you were busted; i don't think it's cool to grow in someone else's house without their permission
