How to Grow and Care Mushrooms in Indoor

Beginner growers can easily cultivate the oyster mushroom. Oyster mushrooms are a simple exotic mushroom to cultivate, and you may use a variety of substrates like straw and wood chips, cardboard, and coffee grounds as a substrate. These popular substrates will assist you in achieving the best crop yields possible.

If you’re thinking about growing mushrooms for profit, oyster mushrooms can fetch a premium price and are in high demand in many places. In around six weeks, you can cultivate an oyster mushroom. Oysters, like most mushrooms, are finest when gathered fresh. If you can’t sell them right away, as previously stated, you can dry them and store them for several months.

Kits Of Mushroom

Mushroom kits are available to cultivate mushrooms indoors. The kits include everything you’ll need to grow mushroom, including spores, spawns, substrate, and more. They’re simple to use and usually come with a pre-inoculated cardboard box or perforated bag for producing a certain mushroom.

These kits normally include enough ingredients to grow various crops over the course of two to four months. Typically, the cost is less than $35 at this time. The kits are also available in gardening stores, some organic food stores, and on the internet. Mushrooms can also be grown in sterilized jars. Spread the spores after filling the jars with your substrate or media. In a jar, controlling humidity and temperature is simple.

Environment

Each mushroom species has its own set of growing and environmental requirements. Beginners should start with oysters or button mushrooms.

Cleanliness

To avoid infection, all mushrooms require a clean atmosphere. If you’re not using a kit and making your own substrate, pasteurize the straw to eliminate any contamination risks. Soak the straw for one hour in hot water (at least 140 degrees F). Drain and chill the substrate. Spread the spawn on top of the straw in the plastic bag until it is completely filled.

Temperature & Humidity

Set up your gear in an area with a consistent temperature. You may need to try different areas depending on the environment where you reside and your lodgings. The majority of mushrooms thrive in chilly, moist environments. The temperature should be between 12 and 21 degrees Celsius with a humidity of 70 to 80 percent. Many bathrooms, kitchens, and basements have these circumstances. Crops require a lot of moisture. The mushrooms must have constant dampness to develop and grow.

Mushrooms will not grow in very dry air. In most regions, a two- or three-times-daily mist from a spray bottle filled with water is sufficient. You will need to spray the mushrooms more frequently if you live in a dry climate. Do not over-spray the cardboard, causing it to get soggy or damp.

Light

Grow them in a cabinet, closet, or other dark location to keep them out of direct sunlight. Some mushrooms, such as oysters, require some indirect light, while others, such as white buttons and cremini, require complete darkness. (Brown caps can be caused by exposure to light.)

Air

Mushrooms require oxygen to grow. Even a closet or cabinet will require some ventilation to avoid carbon dioxide buildup (CO2). Too much CO2 can stifle mushroom development or even cause it to halt entirely. For air circulation, a fan may suffice.

Equipment

After purchasing a growing kit you will need:

  • Electric fan
  • spray mist bottle
  • cooking oil spray
  • bleach

Growing Mushroom kit in a Plastic Bag

Soak the straw for the substrate for one hour in hot water (at least 60 degrees Celsius). Drain and chill the substrate. Spread the spawn on top of the straw in the plastic bag until it is completely filled. Tie a metal tie around the top of the bag. Perforate the bag all over with small holes to allow air to circulate.

For around 2 weeks, place the bag in a warm area. As the mycelium colonizes the bag, it will turn white. Fruiting should begin in a few days once the bag is fully colonized. During this time, you can place the bag in a cooler with high humidity to encourage fruiting.

When the veil that connects the cap to the stem begins to tear, it’s time to harvest. Before the caps flap and release spores, oyster mushrooms must be picked. Each day, rotate the bag to look for mushrooms that are ready to be harvested. Turn and pluck the mushrooms gently to remove them, leaving any broken stems behind.

Substrates for better Growing

While spawn can grow mushroom, cultivating them in a substrate such as straw, cardboard, logs, or wood chips will yield more and better mushrooms. Commercial producers like to employ compost that contains a combination of straw, corncobs, gypsum, cotton and cocoa seed hulls, and nitrogen additions. Supplements of nitrogen and gypsum are added.

mushroom substrates

Mushrooms require nitrogen and carbohydrates in order to thrive. Mushrooms break down carbs in the substrate to produce glucose. This nourishes the mycelium by moving through it. The concentration in the substrate should be less than 1% and never more than 2%.

Bulk substrates include:

  • Mulched straw (wheat, rice or other)
  • Waste or recycled paper
  • Straw bedded horse or poultry manure
  • Corncobs
  • Cottonseed hulls
  • Coffee grounds
  • Nut and seed hulls
  • Soybean meal
  • Cocoa bean hulls
  • Cottonseed meal
  • Wood chips or sawdust
  • Brewer’s grain
  • Ammonium nitrate
  • Urea

Always ensure sure all surfaces have been cleansed with a 10% bleach solution before spreading out the straw substrate to cool. Before and after working with substrate and spawn, wash your hands thoroughly.

Common reasons for failure to grow Mushrooms & solutions

It is not difficult to grow mushrooms if you follow the required processes and have the necessary information. Meeting the demands of mushrooms necessitates careful consideration of the surrounding environment and conditions.

One of the most common reasons individuals fail to grow mushroom indoors is that they do not maintain proper humidity levels for growth. You must remember to sprinkle your mushrooms with water every day unless you have a humidifier (and do not oversaturate).

Another flaw in mushroom cultivation is the lack of sanitation facilities. It is vital to maintain a high level of cleanliness in order to avoid contamination. A 10 percent bleach solution should be used to clean all surfaces and items that may come into touch with spawn substrates or containers. Before and after working with your mushroom crop, wash your hands.

Toxicity

99% of mushroom are safe to eat and have low to no toxicity. Animals are poisoned by certain mushrooms. Take extra precautions to keep your mushrooms out of reach of pets just to be safe. Contact your veterinarian, a pet emergency hospital, or an animal poison control center if you fear your pet has eaten a dangerous mushroom.

Make sure they know what kind of mushroom your pet ate. If you encounter the fungus in the field and are unable to identify it, bring a sample or a photograph to the nearest emergency center.

Pests & Diseases

Parasitic insects, bacteria, and another fungus can all impair mushroom productivity. The eggs of the sciarid or phorid fly can be laid on the substrate. These worms spawn and ruin mushrooms at any stage of development. To keep insects from getting to your mushrooms, spray the box top flaps with cooking oil spray.

Nematodes, which are microscopic worms that consume plants and fungi, are also present. Because the mycelium of oyster mushrooms is carnivorous and eats bugs, they are unaffected. To combat bugs, insecticides and sanitizing treatments are available.

Mold

Trichoderma green mold, among others, can have a substantial impact on mushroom growth. If mold appears in or on your kit or substrate, you must stop production, discard all damaged material, and thoroughly clean the area before restarting.

Preservation of Mushroom

When the mushroom is harvested, they are at their best, and this is when you should consume or sell them. Mushrooms that are collected at the correct time can be stored for later use. If you can’t sell your mushrooms or wish to conserve them, you can freeze or dry them, as previously suggested. These techniques will keep your mushroom fresh for months.
