Millet Spawn Bags

"Small Grains, Big Results"

Sterilized Millet Spawn Bags

Pre-sterilized millet bags designed for rapid colonization and smooth transfers. Small grains mean more inoculation points for fast, even growth—ideal for both bulk expansion and grain-to-grain work.

Lightweight, beginner-friendly, and trusted for clean, consistent results.


Why growers love it

  • Fast colonization with tiny, nutrient-packed grains
  • Perfect for grain-to-grain transfers or bulk expansion
  • Lightweight and beginner-friendly

What’s inside

  • Grain: Premium millet, sterilized and perfectly hydrated
  • Hardware: 0.2 μm filter patch + self-healing injection port
Usage (quick guide):
Inject liquid culture or spores through the port. Incubate at ~24°C (75°F) for 7–10 days. Shake gently when you see mycelium spreading for even colonization. Use as-is for fruiting or spawn to bulk for larger harvests.

Quick Start

  1. Inoculate: Inject LC or spores through the port.
  2. Incubate: Keep warm & dark (~24°C / 75°F) for 7–10 days.
  3. Expand: Use as-is for fruiting, or spawn to bulk for bigger harvests.

Pro tip: Shake the bag once mycelium starts to spread for even colonization.

Reviews

Michael R.

Toronto ⭐⭐⭐⭐⭐

Tried growing mushrooms at home for the first time – and it worked perfectly! The bag is convenient, no need for sterilizing anything. Within a few weeks, I had fresh mushrooms

Jessica L.

Vancouver ⭐⭐⭐⭐⭐

Super easy for beginners. Just added the mycelium, kept it warm, and forgot about it – the mushrooms grew on their own. Tasty and hassle-free!

Daniel M.

Calgary ⭐⭐⭐⭐⭐

"I’ve tried other methods before, but this one is really the simplest. Great yield, the only downside is that I wish the bag was a bit bigger

Sophie K.

Montreal ⭐⭐⭐⭐⭐

A fun idea for the home! My kids and I grew mushrooms right in the kitchen, and it was so exciting to watch the bag turn white. The kids loved it!

Ryan D.

Ottawa ⭐⭐⭐⭐⭐

The harvest exceeded my expectations – I got more mushrooms from one bag than promised. And the taste is way better than store-bought
