I had a question for people who have their growroom in a second bedroom or whatever. Say you have a grow tent. 8x8x3 apprx. sitting in your second bedroom. Noise is no issue here or smell. The person in question never has people over but when they are over, what if they ask to see what's in your room? If they do ask they are nosy, shady, and would never be allowed in the place again. No one has ever asked but what if your family comes over and wants to know why the door is always closed/locked? What's a good and believable excuse? If friends or the such come over the excuse could be that the cats are in there locked up so they don't bother company.
Is, "it's my storage room, full of junk, really messy, don't want anyone seeing it right now" a good excuse? What about "I just used my Hoover SteamVac (as it's sitting just outside the door) to clean the carpets, don't want anyone in there at the moment"?
