Hey, I like what you're doing so far
I'm a big fan of 12/12 from seed. Don't listen to what other people say about it. 99% of the time they didn't even try it. I have one bagseed going at 12/12 from seed and she's one big mofo hehe.. The thing about 12/12 from seed you need to know though, is that LSTing gets a little bit more difficult, especially with the main cola because the stems get really woody quickly when they're in flower.. You sure can do it with the side branches though!
I'm in for this one
good luck!
Check out my 12/12 from seed too for more help. Looks like mine and yours is almost in the exact same timeframe
