This kit arrives fully colonized and ready to fruit, allowing you to start growing immediately with minimal effort. Simply cut, mist, and watch clusters of dark gray to charcoal mushrooms develop in just days. Designed for indoor growing at room temperature, this kit is ideal for kitchens, grow tents, or any well-lit space out of direct sunlight.

Instructions

Getting Started:

Your Black Pearl Oyster Mushroom Grow Kit arrives fully colonized and ready to fruit. Choose an indoor location with indirect light and stable temperatures. Grow tents (ideally) or on the kitchens countertops.

Ideal Conditions

• Temperature: 60–75°F
• Light: Indirect or ambient room light
• Location: Indoors, away from direct sunlight or heat sources

Using clean scissors or a sharp knife, cut a small “X” or slit on the front of the bag where indicated. This opening allows fresh air exchange and gives the mushrooms a place to form clusters.

Daily Care (The RMS Way):

1. Mist the cut opening 2-3 times daily with spray bottle.
   avoid pooling water inside the bag
2. Focus misting on the air around the opening, not directly on forming mushrooms
3. Keep substrate moist but never waterlogged
4. Ensure good ventilation—mushroom need fresh air to develop properly. Stale air can cause long stems and small caps.
5. Within 5–10 days, small mushroom pins will begin to form at the opening. These pins will rapidly develop into full clusters over the next several days.
6. Be patient—this variety takes slightly longer than pink or blue oysters but is worth the wait

Harvesting for Best Results:
Harvest your Black Pearl Oyster mushrooms when the caps are fully formed but still slightly curled at the edges. Cut or twist entire clusters at the base. The long edible stems are a bonus—don't trim them off!

Getting Multiple Flushes (RMS Method):
After your first harvest, continue misting the block lightly once per day and allow it to rest for 7–10 days. Keep the block in the same growing environment.

Once new pins appear, resume regular misting. Many Black Pearl Oyster grow kits will produce a second flush and sometimes more, with slightly smaller but still high-quality mushrooms.

If growth slows, increasing fresh air and maintaining steady humidity often helps trigger new clusters.
