I'm growing Bubba Kush Katsu cut for the third time. The first time I put it outside and got some nice smoke. The second round I tried topping to leave 5 or 6 tops per plant. But I made the mistake of not removing the large fans that block the bud sites.
Below the leaves, the buds were half the size. I got my worst yield ever off any grow with these. They were vegged for 6 weeks, but growing it bush style was inefficient for this kind of plant. I did cut off all buds the bottom 2/3 of each branch leaving only a grow tip.

(Bottom Pic:)Now I'm moving into week 9 of veg. and I'm using a screen to maximize the number of bud sites. I have been removing any fans that block any buds. The buds then grow up and pump out new fans. I've never pruned as much as I have on this grow.
From what I've read, Bubba only yields packing them in like 4 per square foot or being patient and growing an enormous bush. Outside , apparently she yields well.
Instead of 5-6 tops per plant, I'll have 15 -20 and none of them blocked or in shadow ,making the most of the footprint of the light.
Hope that helps you. Just to compare. A single Chemdog D yielded as much as 4 Bubba Kushes. Same sized plant too. The buds are all leaf, once you cut them away, you'll have plenty of hash material.
