• Original Sensible Seeds: Long-Standing Breeder from Wales

Original Sensible Seeds brings together a small group of breeders with plenty of experience in producing feminized cannabis seeds. The company began in 1992 in South Wales, the same region where Howard Marks, also known as Mr. Nice, was born. Back in the 1990s they created one of the strongest strains of the time, Bigger Pine, which later appeared in crosses like Bigger Pine x Haze.
