All MJ can be grown in or outdoor.
Alll that is saying is afghani grows better then most MJ outdoors because of the short hieght and short flowering time.

In hieght order from smallest to biggest...Afghani-widow-Big bud super skunk.

The afghani is a pure indica.
Widow is mostly indica.
Big bud super skunk is mostly Sativa(Look for the bottom branches don't break from heavy yield with this strain.) :thumbsup:
