What’s inside

  • Grain: Rye + millet (sterile, perfectly hydrated)
  • Substrate: CV / CVG or CVA (coco, verm, + gypsum/azomite)
  • Hardware: 0.2 μm filter patch + self-healing injection port
Usage (quick guide):
Inject LC or spores via the self-healing port. Incubate at ~24°C (75°F) for 7–10 days. Once white with mycelium, break & shake, then add two small top slits for fresh air to activate fruiting. Harvest after 7–12 days.

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. Activate fruiting: Break & shake when white. Cut two small top slits for fresh air, then wait 7–12 days.
You’ll also need: Liquid culture or spore syringe, clean gloves, alcohol wipes.

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
