Lead time applies to 3 kg kits only. The lead time shown above the “Add to Cart” button is the time needed to prepare your order. A product showing as “in stock” means it can be prepared within that lead time, not that it is ready to ship immediately. 1 kg kits ship within our standard handling time when in stock.

What’s Inside
Everything you need is included — just spray 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.

Our bags: We use Unicorn grow bags, made in the USA. Unicorn is the only grow bag in the world independently tested by Eurofins (a third party lab in Europe) and certified to EN 1186 and USFDA 1520 standards for plastic migration into substrate. Tested at 121°C for 3.5 hours. No other PP or PE bag manufacturer has achieved this food safety standard.

About Yellow Oyster Mushrooms
The Yellow Oyster (Pleurotus citrinopileatus), also known as the Golden Oyster, shares its rapid growth cycle and preference for warmer temperatures with its pink relative, but brings its own distinct character. The vivid golden-yellow caps are visually striking, and the flavour is delicate with a subtle fruity note when cooked lightly, developing a richer, nuttier taste when sautéed.
Yellow Oysters are a good source of B vitamins including niacin and riboflavin, as well as potassium. Like other oyster species, they are also studied for potential cholesterol-lowering and immunomodulatory properties.

Growing Conditions
Humidity: 85–95%. Mist 2–3 times daily. Stop misting once baby mushrooms begin to form. Spray the surface the mushrooms will fruit from, not the mushrooms themselves.
Light: Indirect ambient light — Yellow Oysters need some light for vibrant colour development.
Air: Gentle airflow to remove CO₂ buildup.
Temperature: 20°C–30°C.

More Than One Harvest?
Yes. Expect 2–3 flushes. After each harvest, remove all remaining fruit bodies, allow the block to rest 3–4 days, then soak in cold water for 2–3 hours before resuming misting.

Common Mistakes to Avoid
Temperature: Too low will stall growth. Too high will dry them out or encourage contamination.
Humidity: Insufficient misting leads to small, dry, cracked caps — especially in dry climates.
Fresh air exchange: CO₂ buildup causes long, stringy stems and small caps. Ensure gentle airflow.
Light: Indirect ambient light is needed for vibrant colour and proper cap formation. Avoid direct sunlight and complete darkness.
💡 Tip: Yellow Oysters are fast and rewarding. Get the humidity and airflow right and you will be harvesting golden clusters within two weeks.

What if pins form inside the bag?
Don’t worry. 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. The internal pins will be naturally aborted as they don’t have space to grow
