Not only did it flower, but its a she!
And she has exploded in the last 3 weeks, you'd hardly think this is the same plant... Check out the killer sativa-ish leaves she has, and nice almost symmetrical (sp?) bud structure.

This seed could be very old - unfortunately I don't remember where I got it. It was popped along with some Oaxacan Sativa and ~ 10 unknowns, from old seeds I had.. It does not appear to be growing like my Oaxacans are, this one has much more side branching, and colors are different - so I don't believe its a rogue from that batch.

Could be 20+ years old (which might explain the slow start), as I saved some seeds from in high school of some really bizarre stuff from the 1980's, some really good red/brown weed from mexico, thai sticks, humboldt buds. I never labeled or even stored them properly - In little bindels inside film containers with notes like "Killer Red from scott", "gregs thai sticks" - I don't even remember which Scott, much less the year lol. I have been trying without much luck to "carbon date them" by identifying the items found near them in the boxes - ticket stubs, coins - like an archaeological dig or something. I found a bunch of them when I moved recently, but have had very little success in germing most of them.
