Runts S1 Project

I may top in the next few weeks and pin this girl down after a transplant. I'll prob move this one to the middle of the newest row if my other runts doesn't sprout. The plant right now is to wait until prob day 20 and take a cutting reverse that and pollinate mom. I need a thick branch to make sure it works. I also have clonex and rooting pods. I've tried before and you can root a cutting of an auto and reverse it for pollen. I want to save and harvest the plant still and I can't do that if I spray a branch still connected with STS. So I figure why not root one?
