Vermiculite is a heat expanded mica mineral which is used in mushroom cultivation as a water reserve, to provide micro-nutrients and to aerate bulk substrates to promote faster colonisation and larger flushes.

Available in both medium and fine grades. We recommend the fine grade as it has a greater water retention capacity and is more suitable for an external casing when doing a ‘dunk and roll’ using BRF cakes.

  • Sterile by nature
  • Soft mica mineral
  • Mould resistant, non-toxic and odourless
  • Minimal dust
  • Provides aeration to substrate

Often used in combination with Coconut Coir to provide a simple bulk substrate for various mushrooms.

Price per litre. Sold in 3-litre bags (or 100l sacks)

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.

  1. steve –

    a little goes a long way!!

  2. Donna –

    does what it says on the tin 🙂

  3. JOHN H. –

    pretty good vermiculite. fine grade. minimal dust. it's nice to get good value without having to order 25litres of the stuff!

  4. Dom Caughey –

    nice fine vermiculite which i use for mushroom cultivation and as bedding for my spiders and spiderlings. good value and free delivery. A++

  5. KAtie –

    An excellent product for mushroom cultivation with the finer grade generally allowing for denser cakes and better pinsets after the dunk and roll. Like previous reviewer stated. It does stick to the cake better than the coarser grades which is all I can get from my local gardening store. Happy with purchase and have lots left over for future grows. Thank you.

  6. Oli –

    so far jars are showing strong signs of rhysomorphic growth. First time I've used the fine stuff but performing good in brf jars

  7. K –

    ordered to use as a dunk and roll casing for my BRF cakes. Delivery was quick. the fine vermiculite sticks to the cake better than the bigger vermiculite. will be using this from now on

  8. MUSHCULT –

    fine vermiculite is all you need for mushroom cultivation purposes. Package arrived quickly, prices are good, had a few free samples, a chocolate bar, a thank you note and an instructional booklet. Can't really ask for more than that – great customer service
