If you live in a legal state and have a card, no amount of electric light can give what natural sunlight will. Also, outdoor is much cheaper to do as well. I live in a condo in Florida so outdoors is out of the question. But if I could I certainly would. If your state is not legal, security is crucial for obvious reasons. Also, most 1st timers tend to be extremely proud and excited about their grows so please take my advice and tell NO ONE but God what you are doing. Good Luck!
