Black Pearl Oyster

Most plant-based alternatives either don't satisfy or don't taste like anything you actually want to eat.

Black Pearl Oyster is the meaty mushroom. Thick, firm caps with a deep umami flavour and a texture that holds its own in a hot pan without going soft or watery. It's packed with ergothioneine - a rare antioxidant found almost exclusively in mushrooms - and it's the variety food lovers reach for when they want something that genuinely replaces meat in a dish.

What you'll taste: Rich, savoury, umami-forward. Slice and sear over high heat until the edges caramelise — then serve on toast, in a wrap, or alongside your next braai spread as the one dish everyone fights over.

First mushrooms in 7–14 days. First flush guaranteed.

Detailed Grow Guide:

Cut an X on the front of your box.

This will trigger the mycelium to get ready to grow mushrooms

(Within 1-30 days)

Maintain a suitable environment for your mushrooms

They like shade, fresh air and humidity.

Use a spray bottle to lightly spray them to keep them happy.

(Don't drench them)

A humidifier helps them thrive on auto pilot

Once they fan out fully, twist and pull them off right away.

Leaving them too long will let them drop spores and decay (this can happen within 24 hours)

Pro Tip:

Cook your mushrooms immediately after harvest for maximum flavor and benefits

How to grow More Oyster Mushrooms

How to turn 1 Oyster Mushroom Box into a bucket load of mushrooms.

Step 1:

Drill holes 15cm apart around the side of a bucket.

Step 2:

Use rubbing alcohol to sterilise the inside.

Step 3:

In another bucket (without holes)

fill it up with chopped straw.

Step 4:

Submerge in boiling water to kill any other mushroom spores inside.

Step 5:

Put the lid on and let it sit for 30 minutes.

Step 6:

Let the water drain out overnight. grab a handful and squeeze. There should be no dripping water.

Step 7:

Now its time to grab your mushroom box. make sure the block inside is fully covered with white mycelium.

Step 8:

In the 1st bucket (with holes), place a layer of straw, then a layer of mycelium until the buckets full.

Step 9:

Place micropore tape over the holes to prevent other spores from landing on the substrate.

Step 10:

Then place the bucket in a cool, dark cupboard for 2-3 weeks until the white mycelium has grown over the substrate.

FAQ's

How long can i store them?

We recommend storing your boxes in a cool, dark spot for no longer than 3 months before using them. They can withstand storage for up to 6 months in the fridge but fresh is always best.

Do I need any special equipment?
No. Just water in a spray bottle and a spot with indirect light. Optional: our mushroom grow tent speeds up growth.

Why do I need to join the Facebook group?
Growing mushrooms is simple, but small mistakes happen. Our group gives you real-time expert support to ensure success. It's like having a mushroom hotline—and it's required for our guarantee.

Will I definitely get 2-3 harvests per box?
The first flush is guaranteed (with group support). Additional flushes depend on two critical factors: (1) harvesting before spores drop, and (2) maintaining ideal humidity, temperature, and air flow. Many growers get 2-3 flushes, but we only guarantee the first.

How do I know when to harvest to get more flushes?
Harvest when caps flatten but BEFORE the edges curl up and release spores. Post a photo in the group—we'll tell you exactly when!

How long do fresh mushrooms last?
5-7 days in the fridge in a breathable container (paper bag). We recommend cooking within 2-3 days for peak flavour.

Can kids do this?
Absolutely! It's a popular school science project. Adult supervision recommended for the cutting step.

What do I do with the substrate after?
Add it to your garden—it's excellent compost! Wild mushrooms may even grow in your yard later.
