OK I know I'm new at the grow but I have been in and out of trouble my whole life and have always had to think ahead before something happens. Im going to make a simple list for people just starting out to be safe. First off we all know the first rule is never tell anyone but like most of use at least one person is going to know. If you do have to tell someone make damn sure you can trust that person with your life cause when and if that time come you dont want to worry about being told on. Being grower is a lot more difficult then some make it out to be and im not even talking about the growing part. Making sure you contain the sounds (fans, heaters, inc) and the smell (during flower and harvest). These two problems can be solved with out much effort. I personalty grow in a basement (not at my house) and I rapped everything in plastic (EVERYTHING) making sure there were not hole for smells to escape. For the sound problem just buy some studio foam its cheat on eBay and you don't need much to silence a few fans. Another problem is power usage. For this problem I turn on a electric heater every few hours so they cant see any kind of pattern (18 on 6 off)(12 on 12 off) at the electric company. And yet another problem is Radio frequency from your ballast (the device that powers you HPS and/or MH lights) interferes with the cable wires and box. You can get a shield or more the wires away from the room. Well this is just a little info hope it helps someone.
