I'm with Ston-loc, I'm a bit confused by your question.
Sativas, which have thinner leaves and grow tall and willowy, give you more of an uplifting energetic head high--better as a daytime smoke. Indicas stay shorter and bushier and have more of a couch-lock kick-back body high--better as a nighttime smoke. THC content will vary by strain, regardless of whether the strain is indica or sativa or a cross. Most strains now are hybrids--crosses with strains being either indica or sativa dominant, but few strains out there that are pure sativa or pure indica anymore. True sativas take forever to flower--14 weeks or more sometimes.
