Mushroom coffee may cost more than regular cups, but the extra investment pays dividends as it increases immunity and energy levels while simultaneously decreasing waste production and supporting local businesses.

Hot water pasteurises are recommended, as this kills competitor mold and helps the mushroom mycelium to thrive. Isopropyl alcohol can also be used.

Preparation

Grow mushrooms on coffee grounds to recycle waste product and take advantage of an abundant source of nutrients. This method has become popular with urban farmers and do-it-yourselfers, with six million tons of spent coffee grounds being sent directly to landfill each year – this cultivation method allows you to reuse those grounds to cultivate mushrooms! Mushrooms are known to decompose the compost into something plants can eat as food while at the same time decomposing into something more suitable as soil amendment.

Start mushroom cultivation today by gathering used coffee grounds from your local cafe and mixing them with some boiled straw as substrate (the medium that mushrooms thrive in). Use clean tools and break apart any clumps of coffee. Or if cardboard suits better for you; its resistance to molds and bacteria means oyster mushroom spawn will colonize faster.

After thoroughly mixing coffee grounds and straw with water, soak for several hours in water to hydrate it and eliminate competing microorganisms. Filtered or spring water may be used, provided it is clean. Once fully saturated with moisture, the substrate should appear white – any signs of green color indicate presence of competing organisms that could potentially prevent proper growth.

Maintain a close watch over your mushroom colony to ensure optimal growth. Once the colony is established, it will continue to expand quickly, doubling in size every day. Without proper care being taken to keep an uncontaminated environment for them to grow in, they may soon outgrow control and begin spreading throughout your home or yard.

Are you seeking an added health boost? Adding mushroom extracts to your morning cup of coffee could provide the boost that’s needed. These supplements contain antioxidants, vitamins, minerals, and polyphenols – providing anti-ageing benefits while improving cognitive functions and increasing anti-oxidant protection. Some strains like cordyceps and lion’s mane are even believed to possess neuroprotective qualities.

Adding the spawn

One eco-friendly method of growing mushrooms at home involves using used coffee grounds and boiled straw as substrate (the soil). This technique provides an eco-friendly means of recycling something that would otherwise go to waste, as well as being an engaging family activity. The process itself is straightforward and the results rewarding; humidity should remain high to foster mushroom mycelium growth while protecting from competing fungus growth.

To create the substrate, begin by turning an old cardboard box or Tupperware bin into a mini greenhouse by spraying its interior with water to increase humidity and boost growth rates. Next, place one jar of mycellated coffee grounds inside as well as one cup of oyster mushroom grain spawn from several online vendors such as Far West Fungi or NW Mycological Consultants into your container.

Step two of mushroom mycelium cultivation requires mixing the spawn and coffee ground mixture, making sure there are no air pockets, before placing it loosely in a plastic bag or other container and cutting four slits into it before sealing tightly. Finally, sprinkle alfalfa pellets – although optional, but improving oyster mushroom mycelium health may lead to another fruiting wave two weeks after fruiting has occurred.

After three weeks, your coffee and spawn mixture should be entirely white in appearance. Otherwise, it may contain mold from competitors or contaminants and should always be handled on a clean surface with handwashing between handlings to avoid contamination by rival mold or contaminants. It is also wise to regularly inspect your bag of spawn for signs of baby mushrooms called primordia during this period.

As soon as your mushrooms have reached maturity, place the bag in a cool and dark area away from direct sunlight and mist daily to activate evaporation and help retain moisture for maximum success. Boiling and chilling regular tap water first may result in overwatering; using boiled and cooled water may prevent this.

Adding the coffee

Each day, 2.25 billion cups of coffee are produced worldwide and their grounds discarded, leaving behind plenty of nutrients that mushrooms adore eating. Unfortunately, though, most end up in landfills which generate methane emissions 25 times stronger than carbon dioxide emissions. Luckily, however, pasteurizing allows the coffee grounds to make them ideal for mushroom cultivation.

To create mushroom coffee in a jar, mix 70 percent fresh, cool coffee grounds with 20 percent straw and 10 percent mushroom spawns in an airtight jar fitted with two small holes at its lid to let air in, covering these openings with micropore tape to prevent contamination. It is crucial that all equipment used during this process be cleaned thoroughly as bacteria and mould growth may occur quickly; using a scale is also helpful in measuring accurately.

After mixing your spawn and coffee grounds together, place it in a warm dark environment for around three weeks to allow it to fully colonize the coffee grounds and start producing white growth on its surface.

Continue adding coffee grounds and monitoring the jar for growth until it reaches nearly full. At this stage, start another one using the same method before filling both at once. When both jars have reached capacity, allow time for mycelium to fully colonize their contents before adding more grounds.

Once your jars are completely myceliated, place them in the fridge for 12-24 hours to undergo cold shock – this process helps certain species of mushrooms fruit more reliably while simultaneously sterilizing coffee grounds to decrease any risk of contamination.

Once the jars have been chilled, remove them and place them in a plastic bag with holes punched through it to help maintain humidity while also protecting both you and your house from any harmful spores. As pins start forming you can transfer them back into the bag before placing in a warm dark location; they should produce caps within 2-5 days; however if gills appear early you should harvest right away!

Fruiting

The coffee mushroom kit provides an easy and fun way to grow mushrooms at home using spent coffee grounds, making this an environmentally-friendly alternative to composting. Mushrooms are incredible creatures; breaking down materials that plants and animals cannot consume into something delicious and useful while leaving behind no waste at all! Plus, those coffee grounds make a fantastic soil amendment or compost material!

Start your kit off right by placing coffee and spores in a sterilized bag or container and placing it in a warm, dark area. Since spores need warmth and moisture in order to colonize a substrate, misting these bags regularly with water helps ensure high humidity.

After one week, your substrate should be ready for fruiting. When coral-like growths begin to appear on its surface, it’s time to move them into their fruiting environment; dark rooms provide ideal conditions where water spraying can easily be monitored and managed; it is also beneficial to place bags inside a box or container for additional protection from insects and pests.

Fruiting may take several weeks. A healthy substrate should quickly produce clusters of tiny mushrooms. If these clusters don’t include full-grown gills or rings-like structures, that indicates mycelium maturation may still be incomplete; alternatively they could indicate too dry an environment; therefore moving to somewhere humider may help improve results.

Cleanliness should always come first when growing mushrooms, as any contamination will ruin the growing medium and prevent a healthy flush of mushrooms. If a bag of substrate becomes infected with green mold, that indicates either inadequate sterilization measures were used or it was inoculated too soon after sterilization; this issue is particularly prevalent when cultivating oyster mushrooms which are especially susceptible to contamination. In such instances, revisit your sterilization procedures and give it another go if this happens again.
