How It Works

  1. Sanitise your hands and workspace. Cut open the front panel of the box to expose the bag.
  2. Cut a small “X” or slit in the front of the bag where you want the Speckled Chestnut mushrooms to form
  3. Place the block in a humid fruiting environment with fresh air exchange and indirect light.
  4. Speckled Chestnut mushrooms will begin forming from the cut. Continue misting daily. Harvest when the fruits are mature. Twist and pull gently, or cut cleanly at the base.

What people are saying

FAQ

Yes - these are pre-colonised grow kits designed to go straight into fruiting conditions.

When conditions are dialled in, the blocks are capable of producing 700g+ across multiple flushes.

The substrate blend includes premium millet, milo, hardwood pellets, soy hulls and gypsum.

Aim for 13–18°C, >80% humidity, indirect light, and good fresh air exchange.

Remove the front panel of the box, cut a small “X” or slit in the bag where it’s exposed, then mist once or twice a day. Keep the cut facing the opening and you’ll see Speckled Chestnut mushrooms begin forming from that spot.

Stored properly - in a consistently cool place, out of direct light and away from excess heat - Speckled Chestnut mushroom grow kits can be held for a short period before fruiting. For best results, keep them sealed in the bag and store them cool (a fridge is ideal if you need to pause fruiting). Avoid warm rooms, heaters, or anywhere temperatures swing a lot, as that can trigger premature pinning or stress the block.

That being said, if you’re aiming for the strongest and most predictable first flush, it’s best not to wait too long. Fruiting within 7 days of delivery is recommended for the most reliable performance.

Our Speckled Chestnut grow kits are produced in-house in the UK and need time to fully colonise before they’re ready to ship. Smaller packs usually go out within 60 days of ordering, as we need time to let the blocks fully colonise before they’re ready. If you’re planning a large bulk or pallet order, drop us a message - we’ll let you know our current production capacity and give you a clear schedule for your batch.
