is it safe and secure to order these things online

[Dick]

Hello, Maybe you can help me I live in an area where there is no indoor gardening supply stores. Needless to say when buying a grow light I prefer to pay cash for fairly obvious reasons...I mean is it safe and secure to order these things online or by mail or is your name registered in some government computer as a possible drug cultivator even though it might be a shed full of tomatoes your intending to grow?? I just like my privacy thats all and I was wondering if ordering these things by mail or internet is in fact secure from the prying eyes of law enforcement. Any personal knowledge regarding this or advice? Thanks for your time.
