SKU N/A Category


Our 2 kg pre-sterilised, ready-to-use Sawdust and Bran Substrate is ideal for mushroom cultivation. Designed specifically for Wood-loving mushrooms, this substrate is hydrated to field capacity, ensuring optimal moisture content for mushroom growth.

This substrate is made from 80% sawdust (from hardwood) and 20% bran. Sawdust is the primary component, supplemented by bran, which provides quick growth because of extra nitrogen. For species like Shiitake and Turkey Tail, a nutrition ratio higher than 20% is not recommended as they primarily thrive on wood and don’t respond well to excess nutrition. Thus, this Sawdust and Bran Mushroom Substrate is an excellent substrate for them. Any medicinal mushrooms are best grown slowly as they pack more medicinal benefits than a mushroom that has grown relatively quickly. (This statement may not be accurate for all medicinal mushrooms).

This substrate can be used for all wood-loving species. Go to Grain Spawn, and click on “Fruiting Temperature tab” for more information.

We use organic Wheat bran and Hardwood Sawdust along with Hardwood chips. When mycelium comes in contact with woodchips while growing, they become really Vigorous—resulting in thicker and faster colonisation.

Source and Quality of Sawdust

We source our Sawdust directly from Tasmania, and pellets are made from Australian hardwood.

  1. Take the bags out of it’s packaging as soon as possible, and keep them at room temperature, away from direct cold/heat sources.
  2. Do not store uncolonised bags in the fridge; only fully colonised bags can be kept to slow down the fungus and delay fruiting until ready.
  3. We recommend that the bags is colonised as soon as possible to minimise the chances of contamination or moisture loss.
  4. Work in front of a flow hood or a still air box or in a room with no air movement with the workspace adequately sanitised.
  5. Mix at least 15% grain spawn or higher of your desired species, mix it thoroughly in the bag, and let it colonise.
  6. Incubate at 22-24°C in a dark spot and keep all the bags at a distance from each other to avoid excess heat.
  7. Temperatures lower than 20°C make mycelium grow slowly, which could allow competing organisms to flourish. Temperatures above 24°C favour competing organisms rather than fungi, which increases the likelihood of contamination. Temperatures around 32-34°C will kill the mycelium.
  8. Prioritise airflow over, keeping the bag in a dark spot. If there is no air current during colonisation, the CO2 buildup inside the bag will not be able to be expelled out of the air filter patch. Excess CO2 buildup will suffocate mycelium, leading to slow growth and mycelium producing excess metabolite as a sign of stress, which changes the pH of the substrate and makes it easier for contamination to thrive.
