I'm a huge fan of White Widow and White Rhino, which are both roughly 60/40 sativa/indica. Both of these strains do benefit from an extra couple of weeks in flower, but I promise you that the slightly extra wait is well worth it. :jointsmile:

Aside from that, I'm not a very big fan of overly dominant indoor sativas. The smoke is almost always fantastic, but the flowering times (and sometimes significantly smaller yields) generally put me off. I have gotten great results from Kali Mist, and it is probably my all-time favorite sativa... but, again, expect to spend an extra month in flower if you plan to grow it. Still, if you've got the time and the patience, I can't recommend that strain enough. Seeds can be expensive, depending on who you buy them from, but you can just do what I did and breed the living shit out of a couple females and have enough seeds to last you for years.

Have fun. :thumbsup:
