Required materials for mushroom cultivation at home:

We need very fewer materials which can be availed easily to grow mushrooms at our home.

  • Mushroom spawns
  • Straw
  • Plastic bags


Spawn is nothing but a vegetative mycelial network of a mushroom developed after the germination of fungal spores. It contains mycelia along with supporting medium, which provides nutrition to the fungus for growth and development.


Purchase the good quality spawn of required type from reliable resources like mushroom growing points, training centers, etc.

Well, dried, fresh straw should be used for mushroom cultivation at homes. Don’t use wet, rotted straw. Avoid bringing straw from unhygienic places.

Select polythene bags of proper size, which relatively think enough to bear the weight of media in it. Don’t use polythene bags, which are very thin. Because they might prone to tearing problems, which totally damages cultivation.


Mostly oyster and white button mushrooms are suitable for cultivation at home.


  • In commercial cultivation, we will use machinery for sterilization as we are growing mushrooms at home; we can do sterilization of media by boiling on the stove in the kitchen.
  • Collect the dried straw and shred the straw into small pieces and boil the shredded pieces of straw by adding water to it for 10 minutes.

Uses of sterilization:

  • Boiling is very important in mushroom cultivation at home because it sterilizes the media from harmful microbes etc.
  • It also softens the lignin and cellulose bonds present in the straw, which facilitates the easy growing of mushrooms and softening of straw to ensure better packing it in polythene bags.
  • Stop boiling after 10 minutes. Avoid excessive boiling. Then squeeze the straws with the hands to remove the excess water.

Drying of the media:

  • Then spread and place the straw in a place with good aeration for drying purposes.
  • Keep it overnight.

Filling the media into a polythene bag:

  • Place the straw in the polythene bags by pressing firmly with hands up to a layer of 2 inches and place a layer of spawn and place 2-inch layer of straw over the spawn.
  • Repeat these layers of straw, spawn, and straw up to 8 -10 inches of height. Then there will be around 4 – 5 layers of spawn.
  • Clean your hands properly before filling the media into the bags to avoid further contamination.


After completion of this operation, we have to twist the mouth part of polyethylene bag and tie it with help of strings.


  • Before closing the bag, remove the all air inside the polythene bag and do not make the straw very compact by pressing should be done gently.
  • Then after closing, makes small holes with the help of a pen, etc. to the polythene bag from where mushrooms growths will come out. Around 7 – 10 holes will be enough.

Placing it in favorable conditions for the growth:

  • Mostly mushrooms grow well in cool, dark and moist places.
  • Place the bag in a dark place.
  • Within seven days, the spores start sprouting; we can observe this by finding the whitish color growth inside the bag.

Relocate the mushrooms:

  • After ten days, the germination of total spawn will occur.
  • Then bring out the mushrooms for dark place and place it in a relatively lighter region of the house.
  • Then make holes every 3 – 4 inches apart on the bag from which growth of mushrooms will come out.

  • Spray the water with the help of rose can or hand sprayer daily to the growing mushrooms.
  • Avoid giving excessive watering. Maintain proper moisture inside the bag because mushroom growth and development are hindered by lack of moisture.
  • After 25 days we can observe excellent growth of mushrooms coming out from the holes which can be harvested and immediately used in the kitchen.

Harvesting mushroom

After 25 – 30 days, we can harvest the well-grown mushrooms by giving a small twist with hand at the base of mushrooms, or we can use a sharp knife to cut the base of mushrooms. We should ensure that there is no damage to the growing mushrooms during the process.


Harvested mushrooms can be stored at refrigerated conditions for some days. However use these mushrooms as fast as possible. Because storing under refrigerated conditions for longer times is not advisable.


As mushrooms are with a wide range of uses we can grow them at homes with little efforts and enjoy all the benefits of mushrooms by bringing down the expenses to purchase mushrooms at shops.
