thats a hard one, since i live alone and have no kids so its not much of a problem to have a whole room that glows like the sun is trapped inside with a forrest of plants lol. although a good idea may be to move your setup if possible to a place like perhaps a room in the basement where your daughter doesnt go/isnt allowed. my buddy has a "work shop" in his basement and theres a "storage door" inside the "work shop" room, the "storage room" is his grow space so you gotta go into the basement, then into his shop then into the grow space, far less likely that his kids will go back there since its his shop with sharp and dangerious tool, hasnt had a problem yet since his kids know that the shop is off limits and is locked, as well the "storage room" is also locked. just an idea to try and keep yourself and family safe. remember with most everyone and especially kids, "Outta sight, outta mind" if they cant see it then they wont think about it. hope this is a plausable and helpful idea to consider... what ever you do, think about it, talk it over with your wife since im assuming/hoping she knows about the tent/plants and see what the best course of action is to curb your daughters intrest. i do though highly recommend something like i said above, remember "outta sight, outta mind"
