My 3 footers @ 7 weeks into flower are about an inch dia. in 2 gal pots...for good or bad, that's what they are...AK47 BTW if a strains DNA plays a role, as I'm sure it does...

I dunno if it makes a diff or not, but since the stem is the main "pipeline" from the roots to the leaves/buds, I would think thickerer is better

Having said this, I have LST'd, trimmed and staked these and I haven't really payed attention to stem thickness that much (or at all, as long as it held the bud up) and have no idea if the manipulating altered natural stem thickness....ah, another question needing answering...guess we need a side by side on this....I'll see about it next batch...
