Well, I decided the way I wanted to sex my plants from seed is to top them, use the tops as clones, and put the rest of the plant outside to sex. So I did that a week ago. I have them labeled by where they are placed:
AW x FireOG #1 AW x FireOG #2 WhiteFire x Larry OG #6
WhiteFire x Larry OG 1 - 5 on bottom, from left to right.
WhiteFire x Larry OG #2, which was my favorite plant of that type, is the one that rooted. I liked it because it was bigger and an obviously different phenotype than the others of its kind. It is also growing the fastest after being topped outside, along with #5 and then AW x FireOG #1.
Anyway, if I can clone doing what I did, anyone can do it. The one that rooted is one that I literally pulled the stem out and looked at the bottom 3 days into it and then repushed it back down inside. I did notice the edges starting to look like the very start of forming of roots when I did it, though.
I soaked the cubes for 24 hours in 5.5 pHd water. Then I added 3ml of clonex to the little tray I was using that they had been soaking in. I swirled it around a bit and then pulled the cubes out and separated them. I took the cuttings with scissors that I did not dip in alcohol, left the lower branching on until like 3 days into it, where I plucked them off with my fingers, and then I've just kept them moist with the humidity dome on and slightly opened on the valves. I spray about 4 different times a day.
edit: I forgot to mention that the reason I only have 2 of the AW x FireOG now is because I wanted to cut down to 8 plants for the tray, and the 4 with the worst internodal structure were of that kind. So I took those out.
