I don't know about their not being anymore original G13s around. Then again, I just might be lucky. My cousin has been keeping this strain going consistently for the past 10 years from clone. He's got a perpetual harvest set up. If there really isn't anymore original G13s going around, then I got the hook-up. Lol. And this shit will put you on couch-lock everytime. 2 or 3 hits will give you the ability to move around. But barely. Anymore than that, and you're literally not doing anything for a long time. I just went and mowed my cousin's yard yesterday, and we didn't smoke til after it was done. Cause he knows that if I get high, his lawn won't get mowed. And climbing the stairs to my apartment was a bitch! Lol.....But, you may have a nice hybrid going on. Or a really good member of the skunk family. Either way, it sounds like you got a really nice strain going on. Clone it and keep it going for as long as you can. You will thank yourself. But if you pollinated it with a male of a different strain, it may not be. There's so many different factors involved in that equation.
