Indoor Mushroom Growing

February 7, 2006

Growing a Mushroom Kit is a simple indoor gardening project that you can enjoy at any time of the year.

Edible mushroom kits are growing more and more popular and can be obtained through various Internet or mail order sources.

Using Gourmet Mushroom Kits

Gourmet mushroom growing kits usually consist of a 12 by 12 inch square block of compressed sawdust that’s been enriched and inoculated with spawn (mushroom seeds) of the particular mushroom variety being cultivated.

Indoor mushroom kits include everything that you need to grow loads of delicious mushrooms just by following the simple directions. You normally soak the kit in cold, unchlorinated water for a few hours and then place it in a dark area with temperatures ranging between 60 – 75 F.

This cold water treatment will stimulate the mushroom spawn to become active and start producing edible mushrooms within a matter of days. Before the mushrooms have finished growing the entire growing medium will be completely covered with mushrooms.

Harvesting Your Shrooms

Once you’ve harvested the first crop of gourmet mushrooms that isn’t the end of your indoor mushroom garden. Allow the spawn to rest for a couple of weeks and then you can repeat the entire process to produce additional harvests of delicious mushrooms.

The subsequent crops of mushrooms will grow smaller and produce fewer mushrooms until the nutrients contained in the growing medium have been depleted. Then the remnants of the kit can be used to inoculate an outdoor garden compost pile or hardwood logs.

Mushroom Varieties for Indoor Cultivation

Popular indoor mushroom kit varieties include: Shiitake, Oyster, Lion’s Mane, Nameko, Maitake, Enokitake, and Cinnamon Cap mushrooms. The mushroom kits can also serve as an interesting project to introduce children to the fascinating world of edible fungi.

If you’re intrigued by the idea of growing your own edible gourmet mushrooms, an alternative to growing them indoors using the mushroom kits is to grow mushrooms outdoors with hardwood logs. Tomorrow I’ll look at the benefits of growing mushrooms outdoors directly on hardwood logs.

    Hi Fareed, I would recommend that you visit http://www.funji.com for more information on growing mushrooms indoors or commercially. They can provide you with plenty of information on growing mushrooms and are also a source of spawn, mushroom books, and various mushroom growing supplies. The mushroom growing kits generally cost about twenty-five dollars, but if you are looking at a commercial mushroom growing venture there are better and more economical alternatives to start your crop. Good luck.

    I am a young man of 26 years old, I’m interested in growing mushrooms of most edible types, I’m living in botswana and it is extreemely hot. I want to grow them commercially but on a small scale. How can I go about doing that?

  • Kenny Point

    James, I’m not sure how well mushrooms would do in your hot climate. Even here in Pennsylvania my mushroom logs don’t produce much during the summer. The cooler months of spirng and fall are the periods when I get the best production out of my mushroom logs. Your best option may be to try growing them indoors. Check out the second comment above for a link to a good source of mushroom growing information that may b useful to you.

    Over what temperature following say a power outage of 48 hours (degrees Celsius) do mushrooms become unviable or dangerous (from an eating perspective) to carry on cultivating?

    I have been told that over 28 degrees is the danger area?

  • Barbee

    Hi Jenny, I am a reader of this site just like you. I saw your question and thought I might be able to help.

    I too have been thinking about growing some shrooms and I found this really cool site: http://www.fungi.com/plugs/plugs.html

    You can do your own search if you wish but one of the ‘keywords’ needs to be: “plugs”. I think they’re called “plugs” because they are wooden dowels that are ‘plugged’ into holes drilled into the logs.

    Good luck w/ your ‘shrooms’!

    BTW on this site there is a photo of the mushroom bearing logs leaning against what appears to be someone’s home. Kenny advised me againt that. (I think it was because if insects and such entering the home-not sure).

    Hi we have a farm in ifafa, we have an old type barn like building and it is quite cold inside, thought it might suite growing mushrooms, we have horses and have old sawdust and manure mixture not sure if this would be suitable we have mushrooms that come up in certain damp places but not sure what kind they are. would you be able to advise if it would be possible to grow mushrooms, we would like to start some kind of a family business… your assistance would be appreciated..

  • Kenny Point

    Hi Dianne, mushroom farmers grow mushrooms in buildings so your barn may be suitable but you’d be better off contacting a commercial grower or your state extension office to get advice on a commercial mushroom production setup for your farm. Good luck.

    I am very interested to start growing mushrooms. This is a all new thing for me but would like to know as much detail as possible. What do I need to Start and what would this cost be to start up.

  • Kenny Point

    Hi Janel, it all depends on the amount of mushrooms that you would like to cultivate. The indoor kits run for around $25… you can obtain spawn or plugs for about the same amount but then you have to locate a source for the logs and perform the labor to inoculate them. Fungi Perfecti is a great source for additional info and mushroom growing supplies.

    In India u can do mushroom farming by following these steps.

    Preparation of Spawn
    Cook the grains (rye/sorghum/maize/wheat) in water until they are ready to burst. Drain off excess water. Mix in 2 percent (w/w) lime (calcium carbonate), fill loosely into glass bottles and plug with cotton. Sterilize them in an autoclave for 30 minutes at 1210C and allow it to cool. Inoculate the bottles with the prepared pure culture and incubate at 250 C for 10-15 days. When the whitish mycelium has spread over the Surface, the spawn is ready for use.

    MATERIALS
    For 100 kg Mushroom production – Dry paddy straw (not more than one year old) -100 kg; gram powder-2 kg; spawn bottles-l0; polythene bag-i kg; water and a shady structure.

    Preparation of Substrate
    Use Dried paddy straw, 500 gms per bed (Hulled maizecob, sugarcane bagasse, cotton waste, paper waste, etc, can also be used instead of paddy straw). Cut the paddy straw into small bits of 3 to 5 cm. and soak it in cold water for 6-8 hours. Take it out and then immerse in boiling water for 15-30 minutes and drain off excess water. Dry the straw in the shade for 2 hours and then use. Remove the spawn from the bottle using a small iron rod with hook on one side. Dip the iron rod in antiseptic solution before use. Separate the spawn into four lots. Fill the first layer with straw bits upto 5 cm height in the bottom of the polythene bag. Sprinkle spawn over the entire surface of the straw layer. Add second layer with the straw bits upto 10 cm height and sprinkle spawn as before. Similarly, repeat the spawning for third and fourth layers of straw bits. Then, fill the final layer with straw bits upto 5 cm height.
    After spawning the beds keep the beds in the growing room for spawn running. Keep bags in the dark for a period of twenty days. White mycelial growth appears throughout the bed.

    Cropping & Harvesting
    After the spawn running period (nearly 15 days), remove the polythene cover and keep in the rack. The relative humidity is maintained above 75% by spraying water on the floor and gunny screens, but watering the beds is avoided for first two days.
    After two days, sprinkle beds with water twice daily. Allow aeration and light for 20-30 minutes in morning and evening by opening windows of the growing room.
    First harvest can be made 24 to 26 days after spawning. Harvest fully-opened mushroom before the edge of the top rolls downward. Two to three harvests can be taken at 7-10 days interval. The yield is about 35 to 85 percent of the substrate (w/w).
