Mondo Grow Kit PES Fresh Mushrooms — UK Edition
Years of refinement have led to the next generation of the Mondo Grow Kit PES Fresh Mushrooms, now better than ever. Compared to the original Psilocybe cubensis kit, this version offers:
- Greater yields — more mushrooms per flush
- Extra flushes* — extends overall harvest potential
- Enhanced contamination resistance
- Simplified instructions
*Strain-dependent; typically, the first three flushes yield the most.
What Makes It Different?
The kit features a proprietary substrate recipe—its formula is strictly confidential. Like other easy-grow kits, it’s fully colonised in the lab, so no additional spores are required. The mycelium is ready to fruit as soon as you begin.
Storage Instructions
It’s best to start cultivation immediately. If needed, store the kit in the fridge (2°C–8°C) for up to two weeks. Wrap securely in a plastic bag before refrigeration.
What’s Included
- 1x Grow Box – contains the colonised substrate (the “cake”)
- 1x Grow Bag – equipped with a micron filter to block contaminants
- 1x Paperclip – for sealing the grow bag
What You’ll Need
- Misting bottle (for humidity control)
- Potable water (for soaking and misting)
- A clean, low-contamination environment
Recommended accessories:
- Surgical gloves
- Face mask
- Disinfectant (for hands and surfaces)
- Soaking bag
- Thermometer
- Heat mat (if room temperature drops below 18°C)
Preparation
- Close all windows to reduce airborne contamination.
- Disinfect your workspace before unpacking the kit.
- Clean your hands and forearms thoroughly—surgical gloves are ideal.
- Wear a face mask to prevent breathing on the kit.
Getting Started
- Fill the grow box with clean, drinkable water and close securely.
- Soak in the fridge for 12 hours.
- Drain any excess water.
- Place the box inside the grow bag with the open end pointing upwards.
- Remove and rinse the lid—keep it for later.
- Fold the bag opening twice (without covering the filter) and secure with the paperclip.
- Return the kit to its carton, with the lid on top, and follow your instruction guide or tutorial.
Ideal Conditions
- Temperature: Maintain around 24°C (never below 18°C or above 29°C). Use a heat mat if necessary.
- Light: Only indirect or artificial light is needed—direct sunlight can harm the mycelium.
Misting & Maintenance
- Begin misting one day after setup.
- Open the bag, spray the inner walls (not the cake), then reseal with the paperclip.
- Mist once daily with four gentle sprays to maintain humidity and provide fresh air.
Growth & Harvest
- Expect the first pins to appear between 5 and 16 days, depending on the strain.
- Mushrooms emerge in flushes—groups of fruiting bodies. The first two flushes are typically the most abundant.
- Harvest when the veil beneath the cap tears; gently twist and pull using clean hands or gloves to avoid damaging the mycelium.
Side Growth
Mushrooms may also grow from the sides if exposed to light. To harvest side growth:
- Remove the cake from the bag onto a clean surface.
- Harvest side mushrooms, then return the cake to continue growing.
Soaking for Additional Flushes
After harvesting:
- Place the cake in a clean or soaking bag.
- Add fresh water and refrigerate (2–8°C) for 12 hours.
- Remove and unwrap, then repeat the initial setup steps to trigger the next flush.
When to Stop
If no mushrooms appear after the second flush within three weeks, or if the kit changes colour (green, red, grey, or yellow), it may be contaminated—dispose of it responsibly.
Spores & Potency
Delayed harvesting can lead to spore release, darkening the cake and reducing potency. It’s harmless but less visually appealing.
Responsible Use
This kit is intended for small-scale home use only. Always follow local regulations and practice responsible use.
