Commercial Ready-to-Fruit
Mushroom Blocks

Single blocks (1–3) are typically dispatched within a few days.

For orders of 4 or more blocks of an individual variety, allow 2–4 weeks as these are made to order to ensure maximum freshness.

Once you receive the block, expect first pins in 4–7 days under good conditions.

Not necessarily. A shaded, humid area with good airflow will work.

For best commercial results we recommend a grow tent or fruiting chamber where you can control humidity (80–95% RH) and airflow.

A hand mister is sufficient for small runs; automated misting systems improve consistency at scale.

Mushroom mycelium is a living organism. Extended time in transit — especially in warm Australian conditions — can stress or damage the colonised block. Express post minimises exposure to heat and dramatically improves the condition of blocks on arrival. Add the Express Post Addon product with a matching quantity when ordering.

Most commercial blocks produce 2–5 flushes. The first flush is the largest, as the substrate is at its most nutrient-dense. Subsequent flushes reduce in size. Soaking the block overnight between flushes and maintaining consistent humidity helps maximise total yield.

Yes. Unopened blocks can be held at cool room temperature (16–20°C) for a short period, or refrigerated at 4–8°C to slow metabolic activity. Do not refrigerate Pink Oyster blocks below 10°C. For best results, begin fruiting as soon as possible after receiving your order.

Bulk pricing applies to orders of 10 or more blocks. Mix and match varieties to reach the bulk threshold. For very large or ongoing commercial orders, contact us directly at hello@kaikaifarm.au to discuss volume arrangements and scheduling.

Green or black patches typically indicate Trichoderma or other mould contamination. This can occur if a bag seal is compromised in transit. Isolated spots on the outside of the bag don't necessarily mean the interior is affected, but if the contamination has penetrated or spreads, it's best to remove the block from your fruiting area to prevent cross-contamination. Email us with a photo and we'll advise.

Yes — local pickup is available from our farm at 654 Main Western Rd, Tamborine Mountain QLD. Mon–Fri 9AM–3PM (closed Tuesday). Pickup avoids shipping costs and means your blocks arrive in the absolute freshest condition. Confirm availability by contacting us before visiting

Temperature needs vary by species: Oyster mushrooms fruit well between 16–24°C; Lion's Mane prefers slightly cooler conditions at 18–22°C; Pioppino fruits best at 10–18°C and benefits from a cold shock; Reishi tolerates warmer growing at 22–28°C. Pink Oyster should never go below 10°C.

Absolutely. Spent substrate is excellent for garden beds and compost. The Tasmanian oak-based substrate is fully colonised with beneficial mycelium which helps build soil structure and feeds soil biology. We even sell spent blocks separately as a garden amendment — earthworms love them.
