Anyone notice that smaller diameter cuttings root easier than larger ones ?

On this I beg to differ as I have grown a LOT of strains and never get hollow stems in soil, but in hydro pretty much anything makes hollow stems for me.

Hmm, interesting.
Never noticed when I ran hydro. Then again. Most of that was SOG...

I do have a strain that has some hollowing of the main stem in soil....

I just don't pay attention to that. Doesn't or hasn't mattered in any run so far...

I know @Renfro is no longer a member here, however I was just doing some research and found that increasing boron will make the stems wooden up so they won’t be hollow
