Hey man, things are all still lookin good to me. Keep it up, whatever you're doin seems to be workin. Are you still in the pc box? I'm doin pc grow myself in a pretty small case, and I'm really enjoying it. I've been impressed with the results so far, and stunned by some of the other RUI pc threads on here.
As for FIM or LST, or FIM and LST... My personal 2cents says just stick with LSTing... That alone will keep you pretty busy in such a tight space, and assuming your vegging before flowering (i've gone 12/12 from seedling) then I reckon you'll fill things out without any problem. I'm not sure I can see the benefit of FIMing in a pc case, as it seems to me to be a process that's really dealing with people who've got room for the plant to grow vertically and therefore go for multiple main colas. But if you're in a pc=box, it makes sense to me to keep everything lst'd nice and low, and let the growth all come from the side of the plant.
heh.. opinions are like assholes... everyone's got one... so take it all with a pinch of salt, as I'm a little stoned right now.
subbed to thread. how'd I not spot this grow earlier?!?
