transplanting

So i have 10 plants in one big containear, and they are all tall and bushy except for 2 and they aren't getting much light and I've tried setting up lights to get to those 2 but I'm not having any muck. So that brings us to the question, what is the risk of digging those two up and moving them?

10plants in one container!? I would split them all up into individual containers before the roots get any bigger. Not only is it going to effect yout yield but also potency. You could get 1 plant that is dank as fuck then the top 2-3 will be some regs, then the rest will be some underfed airy ass buds.
