The most recent ones I've grown have been from fast buds, Barneys farm, and now mephisto. If you prefer bigger plants I could point you towards Barneys farm critical Kush, it doesn't start flowering til week 5 but takes longer to finish mines went 100 days, but yielded a qp. (It lab tested at 24% total cannbinoids and 20% thc!) My favorite fastbuds strain was fast berry, if your looking for pretty purple buds that smell like a Christmas tree, this is it, both my phenos were anyway.. I tried their girl scout cookies it had big fat buds, probably some of the bigger buds I've grown, both of those strains stayed pretty short also.
