Your grow has one
enemy. Give it a
shield.
One 20-gram dose of concentrated soil biology stands between your substrate and Trichoderma — the green mold that ends more grows than any other cause. It also feeds colonization and lifts what you pull at harvest.
✦ Three jobs, one sachet
It doesn't just suppress mold. It re-engineers the substrate around your culture.
Mycelium Shield is a defined community of protective bacteria and fungi. Stirred into hydrated substrate at spawn, it colonizes the surface before contaminants can — then keeps working through the whole run.
DefendA living barrier at the surface
A microscopic biofilm sheets across the substrate and physically — and chemically — blocks mold spores from ever germinating.
AccelerateFaster to full colonization
Nitrogen-fixing bacteria feed rapid mycelial expansion, so the culture runs the block and reaches pinning sooner.
MaximizeMore weight off the same block
Phosphate-solubilizing microbes unlock nutrients already bound in your substrate and hand them to the mycelium.
One step. Then it works on its own.
- Dose1 g per 20 lb of hydrated substrate — a level scoop.
- Add atSpawn. Mix through evenly before you bag or fill trays.
- WindowStays active from inoculation through colonization and fruiting.
- StoreCool, dry, out of direct sun. Use within 24 months of opening.
✦ What the sachet buys you
The numbers growers care about
Figures reflect internal substrate trials and grower reports against untreated blocks of the same recipe. Results vary with species, substrate and environment. Mycelium Shield is an input for cultivation, not a food or drug.
✦ How it's held to spec
Boring on purpose.
Exciting inoculants are the ones that fail. Every lot of Mycelium Shield is built to the same strain list, the same moisture, the same plate counts — checked, logged, and rejected if it drifts. No new formula chasing a trend, no seasonal surprise in the bag.
You want the least interesting thing that ever happened to your substrate. That's the whole idea.
✦ Made in the Bernese Oberland
Formulated where the air is thin and the standards aren't.
Mycelium Shield is blended by Zulgtal Laboratorium in Eriz, a valley village above Bern, Switzerland. Each lot is built from a defined strain list, dried to a stable powder, and checked before it's filled — so what reaches your grow room is the same culture every time.
The result is a single-step insurance policy: open, stir, colonize.
Be first when the next batch fills.
