INSTRUCTIONS FOR USE
- How to use?
Add ~100 g of grainspawn to the substrate bag and melt the bag to exclude air. - How to do it?
To prevent spores from dispersing, we recommend working in a sterile environment protected by HEPA filters
(e.g., laminar flow hood) or in a still air box.
What’s in the UNGU box?
Inside, you’ll find a pre-colonized substrate block, a humidity bag, and a short growing guide. It’s all packed conveniently and ready for your first harvest.

How to open it properly?
Tear open the box lid where marked. Then, using a clean knife, cut an X-shape into the plastic packaging at the same spot. The block is ready to grow – keep it in the same position as in the box.

Care tips
Mist the block with clean water 2–3 times per day. Avoid direct sunlight, heat sources, and drafts – mushrooms prefer a cool, bright, and humid environment.

Storage tips
If you’re not ready to start growing yet, keep the kit in the fridge (+1 to +5 °C) for up to one month. Important: do not remove it from the bag and store it horizontally.
