If you are working with our Grain spawn and do not want to use up all the spawn in one go, or inoculated a grain bag with agar, for which you had to cut open the bag but have no way to seal the bag again consider to have our Small Sealing Bag Clips
Do not risk contamination, that is why we have these clips for you.
Why are 500gms better than 1kg bags-
- Faster colonisation
- They are smaller, so they are easier to manage
- They are easy to place in the fruiting chamber as their height is not too big.
The consistency of the bag is really light, and mycelium vigorously colonises it. Let’s be honest; these bags are not meant to give you a heavy flush of mushrooms. These bags are designed to colonise fast and give you the mushroom at the fastest possible time.
Each bag must be removed from the mushroom grow bag once they have completely colonised and must be introduced to the fruiting chamber. There are plenty of videos to make your own fruiting chamber on YouTube!
This is the simplest way of growing your own mushrooms, as you do not need a grain transfer or substrate transfer. Grow directly out of the bag.
One of the easiest methods is to create a mono-tub and fill it with Perlite (easily available in Bunnings). Add some water and put the colonised bags on top of cardboard wrapped with aluminium foil so that the mycelium block does not touch the perlite. Don’t add too much water, as the purpose of water is to maintain humidity inside the monotub. If you are in any trouble regarding this, we are happy to assist you.
Before you order: Test your 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.
How to inoculate?
- 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 swab or spray with isopropyl alcohol.
- Shake the LC syringe and Flame sterilise the needle.
- Cool the needle for a few seconds and inject around 5 ml of liquid culture into the Brown Rice Flour + Vermiculite Bag.
Once ready to fruit, use the following method-
1) Once the block of Mycelium is colonised, cut the bag open and place the bag’s contents in the fruiting chamber. Mushrooms will start growing in 7-8 days, depending on the variety.
2) Once you have harvested your first batch, keep the block submerged in Sterile water in the fridge overnight (Boiled water which was cooled down). This will hydrate your mycelium block and is ready for the second flush
During the second or third flush, the contamination rate is high if the sterile technique is not maintained.
This bag can give you your own mushrooms in less than a month.
In case you wish to make your own BRF bags, we also offer Brown Rice Flour in bulk.
