Lock up unit as in a storage unit you rent? if so, then hell no your asking to get caught because,i dont even think they even have outlets inside them to plug stuff in. As well as from what it sounds like,your going to be growing on property that isnt yours which is uncool if thats the case.

However if it's your office or shop your setting it up in then be 100% discreet and tight lipped,somewhere noone but you is allowed to go. God forbid you have some hypocritical asshole who finds it.
