Auto Onyx by Short Stuff SeedBank was our first ‘Next Generation’ Auto strain and its amazing yields and quality continue to make it one of our best seller.
Onyx has a very interesting genetic background which contributes to its extra height and potency. Breeder Stitch who created Onyx tells us: “Onyx is a secret stabilized plant which includes AK47 x White Russian and diesel, but many more…This plant is quite tall, between 50 to 90cm tall, very branchy, fruity taste, very good producer… This strain is going to be a legend and could be the most worked auto strain ever, result of the biggest selection from crosses we have ever done!”
The introduction of Diesel gives Onyx a wonderful stinky aroma and the AK47 guarantees that knock out stone you have come to expect from the classic serious seeds strain. The White Russian contributes with tons of THC crystals and a very tight flower structure meaning each bud from an Onyx plant really carries some weight.
