About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.

Auto Mass and the Grass-O-Matic Blueprint
Auto Mass is Grass-O-Matic's take on mass-production genetics stripped down to their essentials. The cross brings together Critical Mass, itself a union of Afghani and Skunk 1, and Lowryder, the ruderalis-based strain that put autoflowering on the map. From the Critical Mass side comes the dense, resin-loaded indica build that made the original a commercial staple. Lowryder contributes the autoflowering trait and the speed. The result is an indica-dominant auto that inherits the best of both parents and drops the complexity growers don't need. These feminized seeds are built for growers who want a reliable, fast-cycling workhorse.
Built to Perform, Whatever the Setup
Seed to harvest in 9 weeks is the headline. No light cycle management needed, Auto Mass flowers on its own schedule, which means you can run it under any consistent light without planning around a flip. The plant stays compact, fitting comfortably into small tents and tight spaces without aggressive training. That said, a ScrOG net works well here: the central-cola structure responds to horizontal training by spreading the canopy and pushing more weight into the main stem. Grass-O-Matic describe it as very resistant and strong, capable of growing in any circumstance, and that holds up in practice. Mould and pests are less of a concern than with more sensitive genetics, making it a solid pick for growers still dialling in their environment.
Sticky, Earthy, and Straight to the Point
At harvest, Auto Mass is visibly resinous. The buds carry an earthy, hash-adjacent aroma with a dank, slightly skunky edge that tracks back to the Afghani and Skunk 1 lineage. Potency sits in strong territory for an auto, consistent with what the Critical Mass heritage typically delivers. It is not the most complex smoke in the catalogue, but that is not the point. Auto Mass does what it promises: fast, resin-covered buds with a satisfying, weighty result.
