Auto Mass (Grass-O-Matic) Feminized

Auto Mass: Grass-O-Matic's Workhorse Cross

Auto Mass comes from Grass-O-Matic, a breeder with a clear philosophy: take proven genetics and make them faster. The cross pairs Critical Mass (itself an Afghani x Skunk 1 hybrid) with Lowryder's ruderalis genetics. Critical Mass brings the indica-dominant structure, density, and resin output that made it a commercial favourite. Lowryder contributes the autoflowering trigger and the compact frame. The result is a feminized auto that carries genuine mass-production credentials without the complexity of a photoperiod grow.

Built to Finish Fast, Built to Handle Anything

Seed to harvest in 9 weeks is the headline figure, and it holds up. No light cycle management needed, the ruderalis genetics handle the transition automatically, so you can run any schedule that suits your setup. The plant stays compact, which means it fits comfortably in smaller tents and tight outdoor spots without aggressive training. If you want to push the central-cola structure further, a ScrOG net works well here; the main stem loads up with resin-coated buds that reward the extra effort. Grass-O-Matic describes this strain as very resistant and strong, capable of growing in any circumstance, that's not marketing language, it's a genuine advantage for growers dealing with variable humidity, temperature swings, or less-than-ideal environments. Compared to a photoperiod Critical Mass, you give up some yield ceiling, but the speed and resilience more than compensate for most setups.

Earthy, Resinous, and Straight to the Point

The Afghani and Skunk 1 heritage comes through clearly in the aroma: earthy, hash-adjacent, with a resinous weight that coats the fingers at harvest. Potency sits in strong territory, qualitative framing only, but the indica-dominant lineage points firmly toward a heavy, physical result. The central colas are the tactile proof point: dense, sticky, and noticeably resinous for an auto of this size. If you've grown photoperiod Critical Mass before, the sensory profile will feel familiar; the format just gets you there in half the time.
