Almost all plants are hybrids, few are pure sativa or pure indica. Certain ones have more indica or sativa dominated phenotypes, but thats a rough way of describing them. Although, for the record: Indica: Tend to be bushy, shorter plants with slighty shorter flowering time, and lots of medium sized leaves Sativa: Tends to be long and "Stringy" in the sense that branch nodes are spread out, often has a longer flowering time then Indica's and very large single leaves as oppose to many. You'll get everything and its uncle inbetween though
Sativas usually produce an energetic and somewhat cerebral high "the intellectual high" is what I call it... Great day-time smoke An Indica will usually produce a lathargic, couch-lock type high. A very stoned feeling where even speaking feels like a chore. Great night-time help you sleep type of smoke. Just thought I would throw this in...
