it probably is an outdoor sativa.. but
just because its leafy doesnt mean it sucks

outdoor bud is usually a little leafier for a lot of reasons, one of them being the dude or dudes who grew it probably had a giant amount of buds to trim in a couple of days, and outdoor sativas are a true bitch to trim... my pops and I spent countless hours trimming up about 10 plants this year, sativa dominant outdoor, and let me tell you.... after a while it gets rough, you just want it to be over lol.
it still can get you ripped, regardless of how much leaf material is left on there, if its good bud that was taken care of and harvested at the right time...
peace
