How to tell if it's Sativa or not?

[caligrown82807]

I heard from a freind that indicas are more compact and sativas are more fluffy....But I dunno if thats true,also I heard indica leaves are fuller as sativas are long and skinny.
Anyone can verify this for me as well?

i think it depends on the grower nd grow room i mean leaves can be more broader if high humidity,density can be changed by light ect.....????????:thumbsup:
