Short, Fat And Lots Of Foliage

hey people im new. i have some very short very busy unknown kush plants that iv been growing in my 2 by 3 grow space that i built. i have alot of foliage as u can see in the pics.
i was woundering? what is the best way i can go about trimming these babys to get the best yield????

I think your gonna need more light than that one cfl correct me if im wrong but I only see that one and as far as trimming im as new to trimming as you are cant help ya there

i also have a 150 watt hps sunsystem light you cant see it but its pretty powerful. the cfl was just for my vegging but it also works pretty well for flowering in those lower areas on the plants. it gives it that extra kick. these are by far the shortest plants i have ever had and they are bushy as hell.
