Our Expert's Opinion NEW

Tony, our resident mycologist, has this to say.

Pros
  • Good Water Retention - Coir and vermiculate are both highly proficient at absorbing and therefore retaining moisture - keeping the mix hydrated.
  • Reduced Contamination Risk - Coir and Vermiculite don't contain nutrients like proteins and sugars which contaminants consume.
  • Beginner Friendly - A balanced mix that's ready to use.
Cons
  • Versatility - Less suitable for species with a higher nutrient demand.
Tips
  • Optimise Environment - Keep your microclimate dialled in to encourage gentle surface evaporation. A lightly glistening surface is your goal — not droplets or dry patches. We recommend the lower holes in your tub should be roughly an 1-1.5" above the substrate layer. This will help clear the CO2 without drying out the substrate too much.

Product FAQs

How do I use this item?
Mix it with a fully colonised mushroom media. We recommend at least an inch covering on top.
Do I need to add any water?
No - this substrate is already hydrated to field capacity. Field capacity relates to the relative moisture content of the soil required for the mushrooms fruiting bodies to harvest.
