Hardwood & Bran Mushroom Substrate Sterilised

Whilst we often maintain a small inventory of most items for immediate dispatch, often, items that are freshly produced, high-volume, or made-to-order may require additional time before they can be shipped.

This additional time is referred to as the ‘lead time’ or production time. Please consider this when placing your order.

The estimated lead times for this product are listed below:

• Orders less than 48 units: immediate dispatch
• 49 – 144 units: 1 week
• 145 – 288 units: 10 days
• 289 – 500 units: 2 weeks
• 501+ units: 2+ weeks

Please contact us if you require larger orders sooner; we may be able to expedite your order for a small fee.

FREE SHIPPING AVAILABLE ON ALL ORDERS OVER £50

Orders are typically dispatched on the same or next working day. However, please allow up to 3 working days for dispatch, plus any additional product lead times, especially during busy periods.

We ship our products in plain, unbranded, reinforced cardboard boxes with ample internal protection.

Our shipping couriers may leave parcels with a neighbor or in a safe place if no one is home to receive them. To prevent this, please select the designated signed-for service at checkout and ensure you are available to receive the parcel. Otherwise, the package will be held at your local sorting office or returned to us. Please note that we cannot be held responsible for lost, stolen, or missing parcels if the signed-for service is not chosen at checkout.

Larger orders that require multiple boxes will automatically be upgraded to DPD Local shipping, as they support multi-parcel shipments. Extremely large or heavy orders may need to be dispatched via a pallet.

If items are returned to us due to a failed delivery, a redispatch or restocking fee may apply. Please ensure that any held packages are collected from your local sorting office within 2 weeks to avoid them being returned.

We highly recommend upgrading to the ‘DPD Express Tracked’ service at checkout, as we find it to be the fastest, safest, and most reliable option. Please note that Royal Mail may occasionally experience delays in their sorting offices.
