Spent coffee grounds are perfect for growing oyster mushrooms. The hot water pasteurises the grounds which removes the competitor organisms that would otherwise flourish, allowing the mushroom mycelium to grow unhindered. The fresh coffee grounds (including any filters) are added to the kit daily, along with some cardboard chips (they absorb any excess moisture), and a small amount of grain spawn is sprinkled on top. Once the tub is full, oyster mushrooms will grow through the hole in the lid around 2 weeks later.
So you've probably heard about this "new" method of growing mushrooms, using spent coffee grounds. Seems like a great idea, just add some spawn to used coffee grounds and harvest loads of mushrooms! this is not a new technique, it has been around for over a decade. Several companies in the usa, uk and europe have used crowdfunding to start up oyster mushroom growing enterprises, using coffee grounds. There are also a few australian startups cashing in on the trend. You can check out how similar some of these enterprises are http://grocycle.
Spent coffee grounds are a hugely wasted resource, they are packed full of nutrients and are perfect for growing mushrooms. I suggest starting with oyster mushrooms as from my research they appear to be the easiest to grow, especially for beginners! mushrooms are also a great growing project for children!.
Firstly order your mushroom spawn, (if you are in australia here is a supplier - https://forestfungi. Com. Au/collections/grain-spawn ). You'll have a better chance of success if you use a high spawn to coffee grounds ratio. I'd start by using around 500g of oyster mushroom spawn to each 2. 5kg of spent grounds. If the vendor you purchase the spawn from also sells filter patch grow bags, i suggest you get one as this will make your growing a lot easier, increase your chance of success by reducing contamination and providing the perfect growing environment for your mushrooms.
Magic mushrooms grow on substances associated with waste — sawdust, deciduous wood debris, cardboard, and cow dung. You’d think magic shrooms grow easily but cultivating them is actually difficult. They can’t grow in ordinary garden soil and the smallest contamination can ruin your entire grow. For shroom farmers, coffee grounds work well for magic mushroom cultivation. This organic material is readily available in many kitchens. Take a deeper look as to why coffee grounds make an ideal substrate for growing magic mushrooms.
Normally when growing mushrooms you need to first pasteurise the straw or sterilise the sawdust. The most common way to pasteurise is using hot water or steam, which is either messy on a small scale or costly and energy intensive on a larger scale. The beauty of growing on coffee waste is that the grounds are already pasteurised by the brewing process; meaning you can completely cut out this energy intensive and costly step.
First, there’s no need to sterilize the substrate anymore. Usually, pasteurized straw or sterilized sawdust are used to grow shrooms and to free those of contaminants, shroom growers use hot water or steam — a messy method which is difficult to scale. Coffee grounds are already pasteurized by the hot water used in the brewing process. This saves you time, effort, and automatically puts you several steps ahead.
Continue reading step 1. Carefully collect the cooled and spent coffee filter, grounds and all, and place it into the container faceup. If using a press or strainer just add the grounds to your container once they are drained well. Step 2. Massage your mushroom spawn bag to separate the grain or sawdust into individual bits to maximize the spreading capability. Step 3. Sprinkle the mushroom spawn sparingly over the surface of the coffee grounds. You only need a small amount. Crack the container lid so it can breathe. The container can be located anywhere, such as a kitchen counter, garage, or any other space where there is indirect light, never direct sun.

It is important to pick an easy to grow species first, and the following species are recommended for beginners based on their high rate of success and also the methods and materials are easy to source. Mushrooms fruit when they run out of space to colonize, so when they take over a log, mulch pile, bag of pasteurized wheat straw, or compost bed they are capable of fruiting. Here are the basics, consult tradd cotter’s organic mushroom farming and mycoremediation book for expertise on the cultivation details to improve and refine your results! you can also check out mushroom mountain university for tutorials to increase your skill level on a particular cultivation style.

We are a social enterprise based in the uk and we’ve been growing mushrooms in coffee grounds since 2011. We were already growing gourmet mushrooms in our local area back then, and came across the idea of growing on coffee waste on the internet and in mushroom growing textbooks. At the time back to the roots had just starting making mushroom growing kits from coffee waste in the us (they since dropped using coffee after admitting they were no good at mushroom growing and outsourced their production to another company!).
Gunter pauli from the blue economy had been promoting the idea too as a great example of a circular economy business model. We were really inspired by the prospect of growing our mushrooms on this widespread waste material so we switched our whole production to growing on coffee grounds. A year later we set up one of the world’s first urban mushroom farms in exeter, uk.
Oyster mushrooms are fascinating fungi that can grow on many different substances, from hardwood logs, wheat straw, coffee grounds, or even old cotton clothing.

Of coffee grounds and turned them into more than 20 tonnes of mushrooms. These days our farm is based in the devon countryside, but we are still focussed on low tech, simple ways to grow mushrooms on coffee and other already pasteurised materials like sawdust pellets. Take a quick tour inside our low tech mushroom farm.
This article on how to use recycled coffee grounds offers details on how using coffee on plants can help them grow better. Using compost made from coffee works wonders, as it contains nitrogen and all plants need this important nutrient, especially lettuce, spinach, broccoli, cauliflower, kale, and brussels sprouts. You can also add coffee grounds to the soil for a better soil structure. Be aware that stronger coffee can be more acidic. But, when you use recycled or used coffee grounds most of the acid has left the grounds and is in the coffee.
Along the way we’ve become experts in the growing mushrooms on coffee and other low tech methods and have taught more than 1000 people in over 50 countries around the world through our mushroom growing online courses.

I did it! here’s my first flush of oyster mushrooms grown at home on cardboard and coffee grounds, in a plastic salad box. I started these with a tissue culture from store bought oyster mushrooms. I cultured them on grain for 2 generations and then used the grain to inoculate a sterilized box of coffee grounds layered with newspaper. It took quite a few weeks and then one morning i looked and this is what i found.
So cool! growing food from waste! if i can do this, you can to. Update: we got 3 flushes of oyster mushrooms from this box of coffee grounds and paper waste. Then i tossed it into the garden and it produced another flush of oyster mushroom the following spring.
Weigh your coffee grounds: 1) oyster mushroom spawn (10% of coffee weight) 2) pasteurised straw or hydrated sawdust pellets (20% of coffee weight) mix together well and place into growing bags. For 1kg substrate or more you will often find that the coffee grounds become too compacted. This happens because the coffee ground particle size is very small. This means the substrate can become too dense and compact, creating poor air exchange for the mushroom spawn.
