Forumula F-03 Fermentation Blend

$11.99 40g pouch

The grain conditioner that keeps koji and tempeh spores fed and breathing.


Formula F-03 is a minimalist, food-focused amendment built for solid-state grain and legume fermentation. Where bulk and wood blends chase heavy flushes, this one has a narrower, more precise job: keep steamed grains and beans loose and oxygenated while giving the culture a fast early boost. The result is cleaner separation, better airflow to the mold, and quicker, more even colonization across the batch.

Two ingredients, no filler — tuned for the koji and tempeh maker who wants consistency from batch to batch.

Forumula M-01 Alkaline Shield Blend

$8.99 40g pouch

The contamination-resistant substrate optimizer for monotubs and bulk beds.


Formula M-01 is a precision-balanced dry amendment engineered to give your bulk substrate a head start where it counts most: the vulnerable first days before full colonization. Bulk tubs and beds are never truly sterile, which leaves them exposed to airborne mold spores. Alkaline Shield tackles that head-on by pushing your substrate’s starting pH into a defensive zone while feeding a controlled, bioavailable nutrient profile that supports vigorous mycelial growth without inviting spoilage.

Forumula W-02 Gourmet Forest Blend

$9.99 40g pouch

The high-nitrogen supplement built for wood-lovers and dense, heavy flushes.


Formula W-02 is a nitrogen-forward dry amendment formulated specifically for wood-degrading and forest-variety gourmet fungi. Where alkaline blends fight contamination by raising pH, W-02 takes the opposite approach — it works with the naturally acidic-to-neutral environment these species prefer, then floods the substrate with the organic nitrogen and trace minerals needed to fuel big, weighty harvests.

Built for supplemented hardwood and straw substrates, this blend is tuned for growers chasing yield: fuller flushes, denser fruits, and stronger performance out of every block and bag.
