Shiitake Ready to Fruit Substrate Blocks (3 x 4.5Kg Blocks)
These mushroom substrate blocks enable you to grow Shiitake mushrooms in the easiest possible way.
The substrate comes in a box with 3 x 4.5kg blocks that are fully colonised and ready to fruit mushrooms.
You can skip the mixing, sterilisation, inoculation and incubation stages, and simply place these highly productive and reliable substrate blocks straight into your fruiting room.
5-10 days later you will have a beautiful crop of Shiitake mushrooms ready to harvest.
The blocks are approved by the Soil Association for use in organic agriculture.
Grown by our partners at Dart Valley Fungi on a blend of locally sourced sawdust and bran.
Each 4.5kg substrate block will produce approximately 1.1kg of fresh Shiitake mushrooms from 2-3 crops over a 3-5 week fruiting period.
The blocks are well suited to both hobby growers and commercial growers.
Minimum Order Quantity & Larger or Regular Orders
Minimum order is 3 x 4.5 kg blocks. The price on this page is the price for a box with 3 x 4.5kg Blocks inc. delivery and taxes.
If you wish to order more than 5 boxes (i.e.. 15 x 4.5kg blocks), or wish to set up a regular weekly delivery, please get in touch with us at firstname.lastname@example.org.
The substrate is incubated for the ideal amount of time in controlled incubation rooms where temperature, humidity and carbon dioxide levels are balanced for optimal mycelial growth.
The substrate is fully colonised when you receive it and you will need a suitable fruiting room environment to grow them in where you can provide the following conditions:
- Temperature: 14 - 20C
- Humidity: 85 - 88% R.H.
- CO2: below 800ppm
- Light: 500-1500 lux, 12 hours/day
Please note that you should aim to place the blocks straight into this environment within 24 hours as they will be ready to start growing.
1.1kg of Shiitake mushrooms from 2-3 crops, over a 3-5 week time period
We dispatch substrate orders on an overnight delivery service twice weekly on a Monday & Thursday, so you should receive your order on either a Tuesday or Friday.
We hold a stock of substrate blocks for immediate dispatch and when they run out we operate a pre-order system where you can order and we will send your blocks as soon as the next batch becomes ready (usually within 14 days).
This page will clearly say if it is a Pre-Order system active, so if you see the option to 'Buy Now' it means they will be sent on the next dispatch day.
