Small cab grow / so far, so good / what to do now?

Hi all, I'm growing a single Female Seeds C99 from seed in a pretty small cab (1'5" x 1'5" x 4'3"), hempy bucket method. It's five weeks since sprout and it seems like it's gonna be a short, bushy little girl. I'm worried about light penetration issues and wondering how to maximize the yield with the small setup and 90w LED that I've got. I see some potential problems with ScrOG in such tight quarters. Defoliation? Some other LST? I'm a first time grower, so any tips or insights would be very much appreciated. What would you do at this point?

Have you tried topping? Once I did that to get a nice bushy rather than Christmas tree look. I've got same problem with my grow is height constraint. Then lst the branches to spread it out more you'll see a lot of growth but not much more height until the stretch during flower. I'm only in my 2nd grow but I topped lst'd and supercropped my girls and they are bushy as hell. Also defoliate what is not getting light but not too much at once or will slow growth down

I would just let her go straight up, Christmas Tree
Drop a couple CFL's for side lighting.

Sweet, sounds like a nice simple plan to me. Just gotta watch my temps if I add extra lights, probably running the exhaust fan full time would take care of it.

Ah also, given the 4' ceiling, when do you reckon I should switch? I guessed accounting for 2x - 2.5x growth during 12/12 would be a safe bet, but have no idea with this strain..
