About this Kit
Complete Kit: Everything you need is included, just spray water and follow the simple instructions.
This kit uses a special Master’s Mix, a blend of sawdust, soy pellets, and water. It’s inoculated with about 300 grams of rye or millet grain spawn to give your mushrooms the best 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’.
Warm White Oyster mushrooms are known for their delicate, nutty flavor and creamy-white, fan-shaped caps. They thrive in warmer growing environments and are especially forgiving of temperature swings. With a quick turnaround—ready to harvest in just over a week—each kit yields approximately 1.5 lb (680 g) of fresh mushrooms with opportunities for multiple flushes.
Humidity: Keep relative humidity around 80–90% during fruiting—mist 1–2 times daily.
Light: Needs indirect light to encourage proper cap and cluster formation.
Air: Ensure gentle airflow to prevent CO₂ buildup, which leads to elongated stems.
Warm White Oyster Grow Kit – Delicious
The Warm White Oyster (Pleurotus ostreatus) stands out with tender texture and a pleasingly nutty flavor. It fruits in clusters that are visually elegant and culinary versatile—ideal for stir-fries, soups, and creamy pasta dishes. Unlike some oyster varieties, these adapt well to a broader temperature range, making them perfect for warm indoor environments and climates.
Step-by-step Instructions & Post-Harvest Care
IMPORTANT— This strain fruits in warmer conditions than many other oysters—check your environment before starting.
Step 1 – Let It Grow
*Take the bag out of its packaging.
*Stand it upright letting the mycelium breath from the white filter and do not cut it yet.
*Please keep it away from direct sunlight, windows, fans, AC, or a wardrobe.
Note: Full colonisation for Warm white oyster blocks can take about 2 weeks depending on temperature ,wait until the block is solid white before inducing fruiting.
Need to Wait?
If you’re not ready to start fruiting after full colonisation, you can store the bag in the fridge for up to a month. Do not store it in the fridge until the bag is fully colonised(white).
Step 2 – Fruiting & Harvest
Once colonised, begin fruiting:
1. Cut: To prepare your side-fruiting mushroom growing kit, start by cutting a 10–12 cm “X” into the plastic on the side of the block, where the substrate touches the bag. This is where the mushrooms will fruit from. After making the cut, gently press out any trapped air inside the bag. Then, take the loose, empty upper portion of the bag (since the block only fills the lower half) and fold or roll it neatly over the top of the block. Secure it in place with tape so it doesn’t hang down or cover the fruiting area. This keeps the cut area exposed to fresh air, encouraging healthy mushroom growth from the side of the block.
2. Mist: Lightly mist the cut area 2–3 times daily and keep humidity high.Stop misting when the baby mushrooms tarts to come out. Constant misting is better than heavy misting.
3. Harvest: Mushrooms usually appear within 7–10 days. Harvest when caps begin to flatten by gently twisting at the base.
Flushes: Expect 2–3 flushes. After each harvest, remove all remaining fruit bodies, allow the block to rest for 3–4 days, then soak it in cold water for 2–3 hours before resuming misting to promote new growth
Common Mistakes to Avoid
Low Humidity: Leads to small, deformed caps.
Poor Air Exchange: Causes long stems and slim clusters.
High Temperature: Above 30 °C slows growth and may spoil texture.
Strong Light: Avoid direct sunlight—it dries the block and harms pinning.
💡 Tip: Keep the environment warm but humid with good ventilation to maximise yields and preserve flavor and texture.
What to do if pins form inside the bag
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.
