Indoor growing became popular in the 80's when CAMP began raiding outdoor crops in the national forest, by 1988 prices had skyrocketed to $65 an 1/8th in CA. People started to move indoors to avoid law enforcement however this process is much more expensive and that pretty much is the only reason indoor growers charge more for their crop. I had a guy tell me outdoor isn't worth shit and I'd be lucky to get $1,000 a lb for it. IMO this guy didn't have a clue what he was talking about. I saw a chick on budtrader looking for bud and explicitely stated "don't try passing that outdoor shit off on me".

The biggest advantage of growing outside is your yeild is double or triple that of indoor growing.
