blueberry bonzai: debate top or tie

has ne 1 ever tried lst with dp blueberry?

here my blueberrys 4 th week flowering.
I did tie them down while in veg, but i have untied most of em now.

awesome dude. incredible, how tall are they?
what is the best way to increase yeild with this strain?

They are about 2ft 6 inches tall.
I grow the in BioBizz light mix, and stick to there feed list.
All working great so far!!

I read in a grow bible that bluebs respond well to topping, and are notoriously hard to clone.

thanks for the input, does ne 1 have bright alternatives to hps during flower stage? I can't find a 400w hps system in any store! i can't buy online.
