Quick facts
About Peak Supply
Cheney sun-grown cannabis since 2014. The producer behind Chong’s Choice WA and Mad Dog 420.
Peak Supply is a Tier 3 I-502 producer/processor based in Cheney, Washington — out past Spokane in the Inland Northwest — and has been growing and selling cannabis in the state recreational market since 2014. The cultivation approach is sun-grown across a tier-3 footprint, with every bud hand-trimmed and double-checked before packaging.
The in-house catalog runs flower-first, with strain rotations across indica, sativa, and hybrid cuts and a THC range in the high-teens to mid-20s. Pricing sits in the accessible band that sun-grown economics make possible. The operation has grown enough credibility on the production side that other brands have come to Peak as a grow partner: in 2017, the Chong’s Choice brand sought Peak out to grow and represent their line in Washington — the kind of relationship that doesn’t happen unless the host operator is doing the work consistently. Peak also operates Mad Dog 420 as a sister brand built specifically for customers reaching for the lowest possible shelf price.
Customers who reach for Peak Supply tend to be budget-conscious flower buyers who want a sun-grown WA brand with a long enough track record that budtenders recognize the name, and shoppers comparing the same producer’s output across different price tiers via the Chong’s Choice and Mad Dog 420 sister lines.
