What’s Inside
Everything you need is included — just add water and follow the simple instructions.
Our substrate is a special Master’s Mix: a blend of sawdust and lupin hulls, inoculated with 300g of millet grain spawn to give your mushrooms the best possible start.
We keep things simple and affordable by sending you a fresh, made-to-order bag, just like real mushroom farms use. No fancy boxes, no sitting in cold storage for weeks. This helps keep your cost down by $10; we pass that saving directly to you. We call these kits ‘almost ready to fruit’.
Blue Pearl Oysters (P. columbinus) are prized for their striking blue caps that fade to grey as they mature. They’re among the most visually stunning oyster varieties. These mushrooms thrive in cooler fruiting conditions and produce quick, abundant cluster flushes with sweet, earthy flavor and meaty texture. They are also high in antioxidants and contain lovastatin compounds that may support healthy cholesterol levels.
Humidity: Keep above 85% RH during fruiting — mist 2–3 times daily.
Light: Needs indirect light to maintain color and form; avoid direct sunlight. 12 hour on and 12 hour off cycle is best.
Air: High fresh air exchange is required.
Storage: Store in a paper bag in the fridge—best consumed within 3-7 days—or dry/freeze dry for longer shelf life.
Pleurotus columbinus, commonly known as the Blue Pearl Oyster, stands out with its beautiful steel-blue caps and tight cluster formations. These mushrooms shine in lighter-colored dishes and salads for their unique visual appeal. When cooked, they offer firm texture and sweet oyster-like flavor with subtle umami—and even impart a bluish tint to sauces when lightly sautéed.
Thriving at cool temperatures (15–20 °C), Blue Pearls are perfect for indoor and temperate climate cultivation. Their fast colonisation and fruiting make them a delight for both beginners and seasoned growers, delivering multiple harvests per kit with consistent results.
Low Humidity — Dry conditions cause caps to crack and clusters to form poorly.
Poor Air Exchange — CO2 buildup leads to long, leggy stems and undersized caps.
High Temperature — Fruiting slows above 20°C and the blue colouring fades.
Strong Direct Light — Sunlight can dry out the block and damage emerging pins.
Insufficient Light — Blue colouring won’t develop without adequate light. Use a full spectrum light source for vibrant results. Cooler temperatures intensify the colour, but note that colour fades quickly as fruit bodies mature, shifting toward grey and tan.
💡 Tip: To keep your fruit bodies compact and vibrant, maintain cool temperatures and fresh airflow—this preserves the gorgeous blue hue and firm structure.
Don’t worry. Just ignore the internal pins. Gently fold the top of the bag to push out excess air, cut a small “X” in the side of the bag (where you want the mushrooms to grow), and begin misting that spot daily. Mushrooms will start fruiting from that cut. The internal pins will eventually be aborted naturally, as they don’t have space to grow.

Checkout out our fine Misting Spray Bottle to produce tiny droplets and keep humidity high. The size of droplets formed can easily be evaporated , this constant evaporation signals mycelium to pin.
Could not fruit the bag, or was it contaminated? Send us a photo or call us, and we will help you resolve the issue.
