Finding room for mushrooms

One of the best things about working on a gardening magazine is that you work on stories such as "how to grow mushrooms at home" and you then start thinking about doing something you've never done before, like growing mushrooms. The May issue of our mag carried the mushroom story, and I just couldn't resist the temptation after reading Cheryl Maddocks' interesting story. Admittedly, she mentioned all the fancy gourmet mushies you can grow, like Shiitake, Swiss Browns, oyster mushrooms etc, but I ended up buying the cheapest $19.95 mushroom growing kit from that extremely large and ubiquitous hardware warehouse chain that all Aussies know about.

Here it is, and as this morning is the first time I have spotted an actual mushroom growing in it, it's time I did my mushroom growing report.

As mentioned above, $19.95. Nice artwork on the box, fills you with the optimism that your mushrooms will all turn out to be red toadstools!

Inside the lid are the destructions on what to do. Note the bit which says "Mushrooms should appear in 21-39 days." In my case the count was the full 39 days, so be patient.

Inside the box, two plastic bags filled with what you need to get started.

First fill the box with the larger bag's contents of mushroom compost (pictured), then spread the smaller bag's contents of mushroom-spawn-impregnated peat moss evenly over the top.

Water the whole lot well with a fine spray of water.

Now, here's the trickiest bit: find a truly dark spot for the mushroom growing kit to live for the next few months. I used an old black plastic recycling bin that fortunately worked out to be a perfect fit over the top of the kit, which is in my very crowded but dry garden shed.

The black bin was a truly lucky find on my part, but hopefully you'll be able to find something similar, maybe you even have one of those old bins yourself, or a friend has one lying around unused. No light gets in under the black bin, which sits flush on the floor, so it's perfect. They sometimes use disused railway tunnels to grow mushrooms, so you get the idea, but areas deep under houses would be another option, as long as the area is dry.

After about a week, a faintly greenish mould appeared on the surface, raising my hopes, but then, suddenly, nothing much happened. For weeks. It has been a long wait. I have occasionally sprayed the area with a light mist of water, and of course I wondered if that was too much or too little, as the instructions say moist but not wet. However, I suspect spraying too little is probably better than too much because... I had completely forgotten the mushroom kit was there in the last week, during which I have been unwell. It was only this morning that I thought "oh my god, the mushroom kit!" and went outside to the shed, lifted the bin and...

Mushrooms! You could be churlish and say it's only two, and that works out at $10 per button, but hope springs eternal. All that white mouldy powder on the surface looks to me like the site of future mushroom cities springing up. The plan is that if I do it right we should get a few kilograms of mushrooms by the end of the production run.

In the meantime, all I have to do is wait. The larger the mushroom the stronger the flavour, or so they say, so I will check on these little guys in two days' time, to get some idea of how fast and big they grow. I have home-made chicken stock in the freezer just waiting to become a soup, and home-grown mushroom soup sounds like my kind of lunch treat.

To be continued, when the crops pop up...

Thanks for sharing what actually goes on with those mushroom kits!
I have seen them at the hardware store and there was something about the box just sitting there that gave me the impression the boxes were not fresh or something.
Is good to see how the spores take off and your re-use of the black recycling box was inspired!
Look forward to the next update.

I grew one of these one year in some extra space in a kitchen cupboard. One thing I found is that the top layer can get a bit hard and crusty, making it hard to tell if it's too dry or wet underneath. So don't be afraid to poke inside on occasion. Too wet just means you end up growing a bit of sludge along with your mushies.

Be prepared for bouts of nothing alternating with bumper crops!

I agree Brendan, the black recycling box is inspired. I bought an identical mushroom kit, from the same large hardware store and I got lots of great mushrooms. Quite a few more, in fact, than the posher mail order Swiss Browns. Now I think I'll be getting another - using a black recycling box (instead of the spot in the cupboard where the dog food resides).

I would love to know how this goes for you. I remember we had a mushroom farm in the kitchen - briefly - when I was a kid, which was fun except I didn't eat mushrooms back then! I've been so tempted to buy a kit, but I always wonder if it would grow enough to make it worthwhile. I'm especially interested in the fancier types, oyster, shitake...

Hi there, would you have their website or contact details to get the mushroom kit? Many thanks

I bought my kit at my local Bunnings store. Not sure of the website address, but I do know that the cost of mailing such a heavy box anywhere in the country adds a lot to the price of a box. So I suggest you have a look at a large retailer for a box to buy and carry home yourself. That way, it will cost half as much as ordering online.

I've bought the 50g spawn ( Mr. Fothergill's) pink oyster , inoculated a few wheat grain sterilized jars and the result was horrible.
And I mean it when I say sterile jars , pressure cooked for 1 1/2 hrs , still air box , gloves , alcohol and bleach spray , you name it.
A week after inoculation the results were horrible.
Not only that none of the 7 jars shown no sign of oyster mycelium growth but there was absolutely not a single millet grain showing any sign of mycelium.
On the other hand , bacteria infestation was visible after 3 days.
I did not expect such disastrous results .
Cheaper, better and faster results can be achieved by inoculating grains with live mycelium from the middle of the stem (it's sterile too ).
A small tray of oyster mushrooms is less than 5 bucks and some shops sell even small trays of 3 different kinds for a few bucks.
Way better results if proper sterile procedure is followed.
