The simple fact of the matter is this: Grow lamp are not illegal and have legitimate uses. How about growing orchids in winter?

If you can legally go to a store and buy something, and use it in it's intended legal manner, then there is no crime. It's only baiting the cops if the cops are using illegal tactics to location growers.

The only thing that separate the cops from the criminal are the rules. Cops follow then, criminals do not. When cops break the rules, they become the criminals. It's that simple.
