Zip, I grew AI for, I dunno, 3 years maybe, and to this day I have to say this is the most potent strain I ever encountered. It just knocks you down. It is stronger than my line of Black Domina that I'm growing at the moment. My strain looked identical to GrowinGreens plants.
I lost my strain eventually because I failed to take like-to-like reference seed and my mothers died off in excessive summer heat. It lives on in my 50% strain Mint Choc, and 20% strain Secret Agent (totally unofficial names btw) but in all my breeding experiments with it, the AI was an incredibly dominant gene line. It completely fused with my foxtail hermie Oaxaca haze sativa and took it over. Even bred back to the sativa again, it still had lots of indica characteristics.
If you can get some of that style of AI it's a rewarding experience believe me.
