Might work okay. I've got a Durban Poison x Skunk #1 plant growing indoors, and it's doing well. It's 87.5 percent Sativa, and definitely looks it. I wouldn't wait to flower for too long though, might have size probs. My plant would probably be six feet tall now if I hadn't LST'd the crap out of it during its life, to keep it just below 4 feet. Pretty sure she's finally about done growing now, at day 18 of flowering.

I was just doing some reading and "Mexican Sativa" is part of the genetic history of my plant (along with Acapulco Gold and Columbia Gold, Sativa variants), which is why I mention it. Other than germination probs (1 out of 10 seeds, but they were old freebies so I expected that), I have had zero probs. This plant is so hardy it's amazing. I took some clones, hope some live, I wanna try growing like six of these.
