I would recommend you try a "mostly sativa hybrid" before attempting any pure sativas... I've grown loads of pure sativas indoors are they are more for breeders and/or well experienced growers looking for something diffrent. It should be noted that many pure sativas do not carry the same type of high profile most are used too... It's much more of a subtle shift in perception than a foggy mind with body ques type of high.
Mostly sativa:
Temple (Bodhi), SSH, Apollo 11, C99, Blue Dream, Choco trip, BSHW, Blueberry (some phenos), JJ's white haze, Vietnam black, Neville's haze, Bangi haze
Pure sativas:
Nigerian/ohaze, Golden tiger, mullum x thai (nev), panama's (gold, black, red), colombian black, Ethiopian, congolese, highland and lowland thai, malawi, Malana cream...
