Is there a specific reason why you want it to be sativa such as racey buzz or something of that nature. The reason I ask is because (as someone already pointed out above) sativas usually are tall plants that stretch quite a bit during bud. Indica's are usually more stout and can be used in smaller locations. I personally perfer the saitiva buzz, but lately it has been making me terribly paranoid. Indica's are more couch lock and lazy like. Ltely this is my herb of choice.

There are some indica/sativa crosses that can give you the best of both worlds, unfortunately I don't know from experience too many. Most the stains I have grown in the past have been mostly Indica with the exception of AK47. My AK's seem to still be on the taller side but grow fairly stout when clipped numerous times and still has that racey euphoric feeling. I think you would be quite happy with them. What is your growing space measurements? I have extra seeds. Let me know.
