I still want to know if he is talikng about using a storage locker at a storage facility. I use to manage one and never thought someone would actually grow in it. Look at it this way. Some of the upper model storage facilities have a 110 outlet in each unit. The power is paid for by the storage company but they only expect people to use the outlet for lights if they are moving in or something. Also, some units have an overhead light in them. You can also simpily take out the bulb and put a 110 switch in there. You can run a HPS 1000 watt light. the storage companies PGE bill would be higher and you wouldnt have to pay for a thing except for the unit ofcourse (approx $100.00 a month for a 10X10). But the question is could you raelly seal the unit up 100% and supply both intake and exhaust to it without no one suspecting a thing. Carbon filter and all
