I pulled this from Cannabis culture Magazine OnLine

By harvesting earlier in the window your buds tend to produce more of a cerebral head high, an effect much more pronounced in Sativas than Indicas. A head high is more psychedelic in nature, providing you with a pleasant mental ?up? state, often ideally suited for social situations when you still need to have your wits and plenty of energy.

If you choose to harvest later in the window, your buds produce more of a body high, which is conversely more pronounced in Indicas than in Sativas. A body high is similar to a narcotic ?down? effect, usually associated with being ?stoned?. A down type of high is often desired in the late evening to calm nerves and drift into sleep.

So this says BOTH what I said(indica/sativa) AND what Faddinator said(head/couch).:thumbsup:

Still can't find what I'd read and mentioned earlier.
