Sterile Millet Spawn Bag

Sterile millet breeding bag - designed for growers who value speed, simplicity and success. These bags are perfect for growing Psilocybe cubensis and other special varieties. The mushrooms utilise the natural benefits of millet and deliver consistent results with minimal fuss.

Why modern mushroom growers prefer millet over traditional rye:

Millet has become the grain of choice for mushroom growers around the world, and for good reason. Unlike old-fashioned rye (which needs to be soaked, cooked and precisely hydrated), millet's small, uniform grains (1-2 mm) work straight out of the bag. Here's why millet is the preferred choice today:

1. Speed wins: Millet has 8,000+ grains per kilogram, creating countless starting points for mycelium and colonising 30-50% faster than rye. This speed leaves less time for unwanted moulds or bacteria to sneak in and spoil the batch.
2. Built-in defence against contamination: The natural husk of millet acts as a protective shell during sterilisation, and millet's rapid growth outpaces contamination. The softer grains of rye can burst open during preparation, releasing sticky starch that attracts unwanted microbes.
3. No preparation, no stress: Forget soaking overnight or simmering – our millet is pre-hydrated to 54-56% moisture, lab-tested for perfect balance. Rye often requires precise water ratios and drying times, which can be difficult for beginners.
4. Space-saving: Compact grains mean more brood per bag – ideal for inconspicuous breeding or small spaces.

Simple millet injection guide for liquid cultivation:

1. Cleaning: Wipe surfaces with 70% alcohol. Burn the tip of the syringe until it glows.
2. Smart injection:
• 2000mL: 5-7mL liquid culture over 3-4 spots
• 4000 ml: 10-12 ml over 6-8 spots
3. Incubate: Store at 22-24°C. Shake gently at 25-30% colonisation (white spots form in 7-10 days).
4. Bulk phase: Once completely white (2-3 weeks), mix with pasteurised coconut or woody or manure substrate.
   
   
   

Why trust these bags?

Each batch passes ATP bioluminescence tests (sterility checks) and moisture scans. We purchase millet from farms in the EU that specialise in low-starch varieties to prevent clumping after sterilisation.
