Description

Your purchase includes:

  • 3 sterilised, ready-to-use bags filled with 1 kg of brown rice flour and vermiculite. Each bag features a self-healing injection port for easy use.
  •  alcohol wipes to clean injection port

These Organic Brown Rice Flour (BRF) & Vermiculite bags are thoughtfully designed to offer the ideal environment for mycelium colonisation. While they may not yield a heavy flush of mushrooms, they are optimised for rapid colonisation and fruiting. They are fruited once its fully colonised and then taken out of their bag somewhere humid.

Procedure for Use:

  • Once your bag is fully colonised, remove it from the mushroom grow bag.
  • Introduce it to a fruiting chamber. There are plenty of DIY tutorials on how to create your own fruiting chamber on YouTube , you can also use our inflatable monotub.

One simple method involves setting up a fruiting chamber filled with Perlite (available at Bunnings). Just add some water and place the colonised bags on top of a piece of cardboard wrapped in aluminium foil to avoid contact with the Perlite. Ensure not to add too much water; the aim is to maintain humidity inside the fruiting chamber.

Inoculation Process:

  • Check the bags on arrival, hold them for at least 5 days and check them again. Inoculate between day 5 and day 13.
  • In a clean environment, wipe the injection port with an alcohol wipe or spray it with isopropyl alcohol.
  • Shake the LC syringe, sterilise the needle with a flame, then let it cool for a few seconds.
  • Inject about 5ml of liquid culture or spore solution into the Brown Rice Flour + Vermiculite Bag.

Fruiting Process:

  • Once the mycelium block is fully colonised, cut open the bag and place the contents in the fruiting chamber. Depending on the variety, mushrooms should begin to appear within 7-8 days.
  • After your first harvest, rehydrate your mycelium block by submerging it in sterile water in the fridge overnight (use boiled water that has cooled down). It will then be ready for a second flush.

These bags are not suitable to be used for growing mushroom in a monotub with more substrate. BRF bags is a traditional way of growing mushroom for someone who does not want to research and want a quick grow sacrificing 80% yield. If you want a better way of growing look at the video on our Inflatable monotub listing and start with a all in one bag or a grain bag.

It’s essential to maintain sterile techniques, especially during the second or third flush, as the risk of contamination increases.

Only order these bags when you have the liquid culture or spore syringe in hand. Test your spore syringe or liquid culture before your bags arrive. This is the single best way to avoid a wasted bag. If your culture turns out to be contaminated and you only find out after the bags have landed, you are left with clean bags and nothing safe to put in them, and the 14 day window will not wait.

When the bags arrive: Check them straight away. You are looking for green or otherwise coloured patches, wet spots, or an off smell. If anything looks or smells wrong, contact us before going any further.

Hold the bags for at least 5 days and check them again. Contamination is not always visible on arrival, and this holding period gives anything latent a chance to show itself. It also protects you, because once a bag is inoculated it can be hard to tell whether a problem originated with us, with your syringe, or with your technique and environment.

Use the bags within 14 days of arrival. Past that, the bags start to dry out and the contamination risk rises.

If your culture has already tested clean and the bags pass their day 5 check, inoculate any time between day 5 and day 13. If you have not tested your culture in advance, plate it on MEA the day the bags arrive, read it at day 7 to 10, and inoculate between day 10 and 13.

With our kit, you can enjoy growing your own mushrooms in less than a month. If you encounter any issues, we’re always here to assist you.

  1. Take the bags out of their packaging as soon as possible, and keep them at room temperature, away from direct cold/heat sources.
  2. Do not store uncolonized bags in the fridge; only fully colonized bags can be kept to slow down the fungus and delay fruiting until ready.
  3. We recommend that the bags are colonized as soon as possible to minimize 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 sanitized.
  5. Mix at least 15% grain spawn or higher of your desired species, mix it thoroughly in the bag, and let it colonize.
  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 favor 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 colonization, 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.
