Really nice stuff you got going there. Do u know where grobotik got theses seeds from,? sams stock or..?
So RM3 u think it is a bad sign that the stem is hollow. I have heard DJ Short mention the stem too, but in his observation he thinks that it is a good sign..? Yeez so many opinions.
"Quoted from DJ's book, taken originally from Micheal Starks Marijuana Poteny , says this
Large hollow stems are are sought over white pith filled stems. Backed by years of observations, hollow stems do seem to factilitate THC produciton. ( from icmag)
Later on DJ changed the stems theory a bit, dunno could´t find any about it.
Well this really dosen´t tell us a lot. Maybe it because of wind, genetics, nutes , who knows.
