If that's meant to be G13 blueberrygum? I grew out a 5pack and they were a waste of time only 2 out of the 5 were good enough to go into flower and one of them hermied on me.
They were grown out with 3 other strains and they were the only dissapointment, poor smoke and yield and I wouldn't grow them out again if I were paid to absolutely shocking genetics that were rubbish from the get go 3 mutants and one of the 2 in flower hermed at roughly week 6.
the other strains they were up against were serious seeds white russian, physcosis (clone only) and the livers/blues (clone only) all yielded well and smoked great with the G13 being the exception, my opinion is the genetics aren't worth the packaging they come in 1 out of 5 is poor and even the one was crap.
Best of luck and hopefully you'll have better luck than I did mate.
