Grass-O-Matic are a relatively small Spanish seedbank who famously became the first breeders to offer fully feminized versions of auto-flowering cannabis strains. Their pioneering years of work in the auto-flowering industry have led to the creation of a range of very stable, high quality strains all of which produce female plants. In fact, they state that their tests prove their seeds will produce female plants 100% of the time. These auto-flowering pot varieties are well loved by growers as they are known for the high quality of the buds, with large yields and vigorous growth. Grass-O-Matic are also known for the great germination rate of their seeds due to strict quality control during production and packaging. All of this makes them a great option for anyone looking to buy autofem marijuana seeds here at SeedSupreme Seed Bank.
