The Mondo® B+ XL Magic Mushroom Grow Kit represents the ultimate extra-large home cultivation kit for European growers seeking maximum volume and heavy harvests. Containing an upgraded 2100ml substrate cake—nearly double the volume of standard 1200ml kits—this Next-Gen Mondo® setup delivers yields of up to 600 grams of fresh Psilocybe cubensis mushrooms across multiple flushes.

Engineered with enhanced mycelial density and improved contamination resistance, the B+ XL kit pairs high-yielding genetics with an extra-large micron-filter grow bag for an efficient, low-maintenance harvest.

Step-by-Step Activation & Cultivation Guide

Follow these steps to activate your 2100ml Mondo® B+ XL kit safely and achieve heavy flushes.

Step	Operation	Key Action Required
1. Workspace Sanitation	Clean & Disinfect	Sanitize work surface; wear sterile gloves and face mask.
2. Initial Soak (12 Hours)	Hydration Activation	Fill 2100ml tub with cold water, cap lid, submerge 12 hrs in fridge.
3. Large Bag Setup	Position Tub & Bag	Drain water, place tub inside large grow bag, fold top twice.
4. Humidity Seal	Apply Yellow Tab	Lock fold with yellow seal tab without covering the micron filter.
5. Daily Misting	Side-Wall Spraying	Spray inner bag walls 4 times daily (never directly on the cake).

Step 1: Sanitation and Workspace Setup

Preventing mold spores and bacteria from settling on your 2100ml cake is critical.

• Close all open windows and doors to stop drafts.

• Clean your work surface thoroughly with a surface disinfectant spray.

• Wash hands and arms up to the elbows, apply hand sanitizer, and put on sterile latex gloves and a face mask.

Step 2: Activating Your Kit (12-Hour Cold Soak)

1. Remove the 2100ml plastic tub from the cardboard box.

2. Fill the tub completely with cold drinking water.

3. Snap the plastic lid securely onto the tub and submerge it in your refrigerator (2°C to 8°C) for 12 hours.

4. After 12 hours, remove the tub from the fridge, open one corner of the lid, and drain all excess water completely (allow it to drain for 10–15 seconds).

5. Rinse the plastic lid, dry it, place it inside its Ziploc storage bag, and keep it in the cardboard box for future flushes.

Step 3: Bag Assembly & Sealing

1. Place the open 2100ml plastic tub inside the provided large micron-filter grow bag with the opening facing upward.

2. Fold the open top of the grow bag twice, ensuring you do not cover or block the micron filter strip.

3. Place the reusable yellow seal tab over the fold to lock the bag shut.

4. Place the entire setup back into the cardboard box on top of the Ziploc bag containing the lid.

Ideal Environmental Conditions for Peak XL Yields

Because a 2100ml cake retains more moisture, maintaining stable climate parameters ensures uniform pinhead formation across the larger surface area.

Climate Parameter	Optimal Range	Operational Guidance
Target Temperature	23°C – 24°C (73.4°F – 75.2°F)	Ideal range for fast pinhead emergence.
Temperature Limits	18°C (Min) – 29°C (Max)	Use a thermo heating mat if room drops below 18°C.
Lighting	Indirect ambient daylight	4–12 hours daily; avoid direct sunlight completely.
Relative Humidity	90% – 95%	Maintained by spraying inner bag walls daily.
Air Exchange	1–2 times daily during misting	Unclip bag, spray walls, allow brief air exchange, reseal.

Temperature & Heating Protocols

Keep your grow kit at a stable temperature of 23°C to 24°C. If ambient temperatures drop below 18°C during European winter months, use an infrared thermo heating mat managed by a thermostat.

Crucial Setup Precaution: Never place the 2100ml grow box directly onto a heating mat. Place an insulating barrier—such as a piece of folded cardboard or a wooden trivet—between the mat and the box to prevent the bottom of the substrate cake from overheating and drying out.

Humidity & Misting Routine

Starting the day after initial setup, manage humidity inside the large bag:

• Remove the yellow seal tab to open the bag.

• Spray the inner plastic walls of the grow bag once per side (4 bursts daily).

• Do not spray water directly onto the mycelium cake or developing mushrooms.

• Immediately reseal the bag with the yellow seal tab to trap humidity and introduce fresh oxygen.

Harvesting Technique & Resetting for Multiple Flushes

The Mondo® B+ XL kit produces mushrooms in waves called flushes. The first two flushes yield the heaviest overall weight and largest mushrooms.

Stage	Operational Action	Critical Visual / Touch Metric
1. Timing	Harvest before spore drop	Pick as the thin veil beneath the cap begins to tear.
2. Twist & Lift	Gentle rotational pull	Hold stem base; twist clockwise slowly until it releases.
3. Substrate Clean	Remove aborts & pins	Clear all tiny pins so the cake surface is clean for rehydration.
4. Cold Soak Reset	12-Hour Rehydration	Fill 2100ml tub with cold water, cap lid, soak 12 hrs in fridge.

When to Harvest

Harvest your B+ mushrooms just as the protective veil beneath the cap begins to tear. Avoid waiting until caps open completely, as they will release dark purple/black spores across the 2100ml cake. While spores are harmless, they signal the mycelium to slow production, reducing the yield of subsequent flushes.

Proper Picking Technique

1. Wear sterile gloves or sanitize hands and forearms thoroughly.

2. Hold the mushroom stem near its base between your thumb and forefinger.

3. Slowly twist your hand clockwise while applying gentle upward pressure until the stem releases cleanly from the cake. Never yank or pull hard, as this tears up substrate material.

4. Harvest all mature mushrooms along with tiny premature pins (“aborts”) before resetting the kit.

Resetting for Subsequent Flushes (Cold Soak Process)

To trigger your next flush:

1. Fill the 2100ml plastic tub with cold drinking water and snap the sanitized lid back on.

2. Place the sealed tub inside a clean plastic bag and submerge it in your refrigerator (2°C to 8°C) for 12 hours.

3. Hang the empty micron-filter bag upside down to dry safely.

4. After 12 hours, remove the tub from the fridge and drain all excess water completely.

5. Place the tub back inside the large grow bag, spray the inner walls, seal with the yellow tab, and resume normal growing conditions.

Troubleshooting & Contamination Control

Managing Side-Pins on XL Cakes

Because light hits the sides of clear plastic containers, side-pins can form along the edges of the tub.

• Prevention: Wrap the outside lower half of the plastic container with aluminum foil or black tape before setup to block side light penetration.

• Harvesting Side-Pins: Sanitize your hands, gently invert the plastic box onto your clean hand so the cake slides out, pick side mushrooms, and return the cake to the box before soaking.

Identifying Contamination

• White Mycelium with Brown Caps: Healthy active growth.

• Blue/Purple Tinting on Stems: Normal bruising caused by handling or direct water contact (psilocybin oxidation).

• Green, Red, Grey, or Yellow Colors: Indicates mold or bacterial contamination (such as Trichoderma green mold). If discolorations appear or no growth occurs for 3 weeks after a flush, dispose of the kit immediately outdoors in household waste.

Frequently Asked Questions

How long does a Mondo® B+ XL grow kit take to produce mushrooms?

First pinheads typically emerge within 5 to 16 days after setup. You can harvest your first complete flush of fresh mushrooms within 10 to 21 days under optimal conditions.

What total yield can I expect from a 2100ml Mondo® B+ XL kit?

A standard 2100ml XL kit typically produces a cumulative yield of 200 to 600 grams of fresh mushrooms across 2 to 4 flushes, depending on care, temperature stability, and sanitation.

Can I store the XL kit if I cannot activate it immediately?

Yes. If you cannot set up your kit right away, keep the unopened package sealed inside a plastic bag in your refrigerator at 2°C to 8°C. It can be safely stored for up to 2 weeks from the production date.
