If the question is "which is more potent weed"

I think its unarguably hydroponic. The overall THC levels of weed in general has sky rocketed since the birth of Hydroponic grown weed and anyone who knows the proven scientific facts would we hard pressed to deny it.
Its clear that many 'prefer' outdoor weed, and there's nothing wrong with this of course, but the most potent weed is undoubtedly hydroponic.
Were it not for hydroponic methods we'd have A LOT less of the fantastic engineered strains we have today.
I read that studys have shown the weed grown these days is up to 20 times the potency of the weed smoked in the 1960's.
On the other hand, cannabis triggered drug induced psychosis is often attributed to high THC hydroponic weed. Its really up to the user/grower.I personally far prefer hydroponic weed, but we cant forget that mother nature has done a great job for over three thousand years...to deny that there is fantastic weed grown with outdoor methods would be down right silly.
In short, a skilled and succesful grower either hydro or outdoor is a skilled grower...either method produces some good weed...and some average weed...but enough theorey...lets just smoke it!
