A successful grow using the BRF tech is smaller in scale, but allows a cultivator to experience and practice the entire process of growing mushrooms. After mastering the BRF jar technique, the game continues into larger scale cultivations.
All-in-one grow bags or grow kits are available from many vendors. Purchasing a pre-mixed, pre-sterilized grow bag is a comfortable option when deciding to grow bigger yields. As long as clean and sterile measures are followed beginning with inoculation, great results can be real. Purchasing a grow-bag/kit takes a bit of the work out of the process. They save time, and can ensure results.

4-6 weeks after inoculating (injecting) the grain bags, there should be an exciting amount of white mycelium growth visible. The spores have colonized through the grain, and will continue to run through the bag. Continue to be patient and do not rush!
If and when the bags look 50-70% it’s time to shake and break up the mycelium to accelerate the rest of colonization. Don’t be too afraid to get a bit aggressive when mixing up the grain bags. The mycelium is well established, and strong. But be careful to not be too forceful and explode the already colonized grains. Have soft hands, but don’t be too timid. Imagine kneading pizza or bread dough. When mixed sufficiently, the bags should look like all the mycelium has disappeared. Fear not, for the mycelium has been mixed in deep and will soon show more growth.
4-6 weeks after the shake-up/break-up, the grain bag should appear completely white with lovely, healthy mycelium growth. This is an exciting time, because the bags are nearing the stage to be opened and released into a chamber to begin fruiting!
Grain bags should ideally have no substrate visible. All you want to see is pure, white mycelium growth. (Don’t worry if you notice some yellowish or light brown coloring through spots–it’s a good sign of healthy mycelial growth. Contamination is unmistakable and immediately noticeable without any question.) Do not rush the mycelium colony inside the grow bag. A desire to open things up and begin fruiting is tempting, but delaying gratification yields more reward. Make sure the bag is completely ready before placing the colonized loaf of mycelium into the fruiting chamber. Waiting to see primordial pins inside the bag is a good test of patience.
When the mycelium has fully run through the substrate and completed colonization, it naturally wants to fruit. After introducing the mycelium loafs to proper conditions, fruiting should begin within days. A week inside the fruiting chamber (given proper conditions) can showcase a loaf’s full potential for a first flush. Long, large mushrooms with huge caps and delicate veils will appear seemingly over night.
Diligently mist the loafs every day with a fine-mist spray bottle, filled with spring water. Also, exchange the air inside the chamber by fanning with a magazine or something useful to get airflow going. Do this process as often during the fruiting stage as possible. A temp/humidity gauge inside the chamber is quite useful to offer a reading, so that adjustments can be made where necessary.
Misting, fresh air exchange and patience can yield a dramatic flush of mushrooms. Good Luck!
