That was the tough part..I don't have the "special" ppm meter so there is a conversion factor to use for our normal ppm meters that do not measure ppms of CS accurately...
This seems highly strain (and luck) dependent..Cackleberry turned easily..Gorilla Wreck#4, not so easy, and the others I tried went full hermie and were destroyed..including my prize GDP clone (MSNL genetics I am running for over a year now). GW#4 pollen was not as potent as the Cack pollen and I only got a few seeds from her..
