Indica is more of a body stone, sort of high were you just want to chill on the couch, make you sleepy and very relaxed. Tends to be a shorted stockier plant I think so more of an indoor grow.

Sativa is more of a head high, you don't feel lazy and just makes anything you do really just that much better.

I've found sativa to be more a daytime smoke and indicas perfect before bed and in the evening.

The effects when eating as far as i know are just stronger, its more likely to cause panic attacks but having never really eatin much I'm not entirely sure.
