Pearl Oyster Mushroom Grow Kit

Grow gourmet mushrooms on your kitchen counter. No experience needed.

This kit is a fully colonized, ready-to-fruit block of Pearl Oyster (Pleurotus ostreatus), the most forgiving gourmet mushroom there is. Cut it open, mist it a couple of times a day, and watch soft, velvety clusters appear, usually within about two weeks. It's happy at normal room temperature, which makes it our top pick for first-time growers and gift-giving.

Three ways to order:

• Made fresh to order (ships in 3–4 weeks): We grow your block after you order, so it arrives at peak vigor.
• Holiday gift (ships week of Dec 14): Reserved from our holiday batch and timed to arrive just before the holidays, fresh and ready to open. Limited quantity.
• Ready to ship (ships in 1–3 days): When we have blocks on hand. If it shows sold out, choose one of the options above.

Includes WeMush tracking: Every kit ships with a QR code linked to WeMush, our cultivation tracking platform. Scan it to log your harvests and follow your grow.

What's in the box

• A fully colonized Pearl Oyster fruiting block in a filter patch grow bag
• Step-by-step growing instructions

You'll need: A spray bottle and a bright spot out of direct sunlight.

How it works

1. Open within a week or two of arrival. The block is alive and ready to go.
2. Cut an X about 2 inches wide in the front of the bag.
3. Place it where there's enough indirect light to read by, out of direct sun and away from heaters and drafts. Not in a cupboard.
4. Mist 2–3 times a day, aiming at the air around the opening to keep it humid. In dry winter air, loosely tent the kit with a clear plastic bag.
5. Harvest in about 1–2 weeks, as the caps go from domed to nearly flat, while the edges still curl slightly down. Twist the whole cluster off at the base.
6. Grow again. Keep misting and most blocks produce a second, smaller flush in about 2–3 weeks.

Good to know

• Ideal conditions: 55–75°F (13–24°C), which suits most homes.
• Long stems, small caps? The kit wants more fresh air or more light.
• Fine white fuzz on the block or mushrooms is usually the mushroom's own mycelium. If a white patch turns green, or a fast cottony web spreads over the mushrooms, that's mold; contact us.
• Spores: Oysters drop a lot of spores as they mature, so harvest on time and don't grow them in a bedroom.
• Freshness matters: If you're giving it as a gift, choose the holiday option so it arrives close to the big day.

Our guarantee: If your kit arrives damaged or doesn't produce when the instructions are followed, contact us and we'll make it right.
