How to use + FAQ's!

Fresh gourmet mushrooms, grown right on your counter.

Bring the magic of mushroom growing into your home with a Tahoe Mushroom Company Grow Your Own Mushroom Kit. Each kit is prepared, inoculated, and colonized locally in South Lake Tahoe, making it easy for beginners, food lovers, families, gardeners, and mushroom enthusiasts to grow fresh gourmet mushrooms at home.

Whether you are shopping for your first kit or scanning the QR code after bringing one home, this page will walk you through everything you need to know.

Our kits are simple to use, fun to watch, and rewarding to harvest. With just a spray bottle, indirect light, and a little patience, you can grow beautiful gourmet mushrooms right from the box.

What Is a Grow Your Own Mushroom Kit?

Each kit contains a prepared mushroom substrate block that has already been inoculated with mushroom mycelium.

The mycelium is the living fungal network that grows through the block before producing mushrooms. Once the block is fully colonized and ready to fruit, you simply cut open the bag, mist regularly, and watch mushrooms grow.

These kits are great for:

  • Home cooks
  • Gardeners
  • Kids and families
  • Mushroom lovers
  • Unique gifts
  • Science projects
  • Anyone curious about how mushrooms grow

Each kit can produce a strong first flush of mushrooms and often a second smaller flush afterward, depending on variety and growing conditions.

Available Mushroom Varieties

Blue Oyster

Blue oyster mushrooms are fast-growing, beginner-friendly, and beautiful. They usually form dense blue-gray clusters and are one of the easiest varieties to grow at home.

They have a mild, savory flavor and are excellent in stir fry, pasta, tacos, ramen, eggs, and sautéed dishes.

Best for: Beginners, fast results, big clusters, easy cooking.

Snow Oyster

Snow oysters produce bright white clusters with a clean, delicate appearance. They grow similarly to other oyster mushrooms and are a great option for anyone who wants a beautiful, productive kit.

They have a mild flavor and tender texture that works well in soups, sautés, pasta, rice dishes, and vegetable medleys.

Best for: Beautiful white clusters, mild flavor, reliable growing.

Italian Oyster

Italian oyster mushrooms are vigorous and productive, often forming large, meaty clusters. They are flavorful, versatile, and great for cooking.

They have a slightly firmer texture than some other oysters and work especially well sautéed, roasted, grilled, or used as a meat substitute in tacos and sandwiches.

Best for: Large harvests, hearty texture, cooking versatility.

Lion’s Mane

Lion’s mane is a unique gourmet mushroom that grows as a white, shaggy, pom-pom-like mushroom instead of a typical cap-and-stem cluster.

It has a tender texture and a mild seafood-like flavor when cooked properly. Many people slice it into “steaks” or tear it into pieces and pan-sear it until golden brown.

Best for: Unique appearance, gourmet cooking, mushroom enthusiasts.

How to Use Your Mushroom Grow Kit

Before You Cut Open Your Kit

Each kit has an estimated cut-open date written on the top of the grow kit box.

That date is a helpful suggestion based on when the kit was inoculated and how quickly that variety usually grows. However, mushrooms are living organisms, and timing can vary depending on temperature, storage conditions, handling, and variety.

Do not cut open the bag just because the date has arrived.

Before opening your kit, check the substrate block itself.

Your kit is ready to open when:

  • The block looks mostly or completely white with mycelium.
  • The mycelium has spread across all or nearly all visible sides.
  • The block feels firm and held together.
  • There are no large uncolonized brown patches.
  • There are no unusual colors like green, black, pink, or orange mold.
  • There is no foul or rotten smell.

If the estimated date has arrived but the block does not look fully colonized, wait a few more days and check again.

It is better to wait a little longer than to open the kit too early.

What You Need

You only need a few basic items:

  • A clean spray bottle filled with clean water
  • Clean scissors, knife, or razor blade
  • A plate, tray, or shallow dish
  • A spot with indirect light and fresh air

Do not place your kit in direct sunlight, next to a heater, directly under a fan, or inside a sealed cabinet.

Mushrooms like humidity, fresh air, indirect light, and stable temperatures.

Best Place to Grow Your Kit

A kitchen counter, table, shelf, or clean room with indirect light works well.

Ideal conditions:

Temperature: Most kits do well around 60–70°F.
Light: Bright, indirect light is best.
Humidity: Mist regularly to keep the fruiting area moist.
Air: Fresh air is important. Do not seal the kit inside an airtight container.

If your home is very dry, especially during winter, you may need to mist more often.

Step-by-Step Growing Instructions

Step 1: Check Colonization

Look at the block through the bag. If it is fully colonized and mostly white, it is ready to open.

If it still has large brown areas that are not covered in white mycelium, leave the bag closed and wait a few more days.

Step 2: Choose the Fruiting Side

Choose a side of the bag where the block looks fully colonized.

If your kit box has a front display window or suggested opening area, position the bag so the mushrooms can grow outward from that area.

Step 3: Cut the Bag

Use clean scissors, a clean knife, or a razor blade to cut the plastic bag.

For Blue Oyster, Snow Oyster, and Italian Oyster, cut a small “X” or slit around 2–3 inches wide.

For Lion’s Mane, use a smaller slit or small “X.” Lion’s mane usually performs better with a smaller opening because it helps encourage one dense fruiting body instead of scattered growth.

Do not remove the whole bag. The plastic helps keep the block from drying out.

Step 4: Mist the Opening

Mist the cut area with clean water.

The goal is to keep the area humid, not soaked. You want tiny droplets and moisture around the cut, but you do not want water pooling inside the bag.

Mist about 2–4 times per day, depending on how dry your home is.

In dry homes, heated rooms, or winter conditions, you may need to mist more often.

Step 5: Watch for Pins

Small baby mushrooms, called pins, should begin forming near the cut.

Depending on the variety and conditions, pins may appear within a few days to about a week after opening.

Once pins appear, continue misting gently. Avoid spraying baby mushrooms too aggressively.

Step 6: Let the Mushrooms Grow

Once mushrooms start growing, they can grow quickly. Check your kit daily.

Your mushrooms need:

  • Moisture
  • Fresh air
  • Indirect light
  • Stable temperatures

If the mushrooms look dry, cracked, or stop growing, increase humidity and misting.

If oyster mushrooms grow long stems with small caps, they likely need more fresh air.

Step 7: Harvest

Harvest when the mushrooms look mature but before they become overgrown or dry.

To harvest, grab the cluster near the base and gently twist and pull it off the block. You can also use a clean knife to cut the cluster close to the bag.

Try to remove most of the mushroom base from the opening so the block has room to produce another flush.

Step 8: Try for a Second Flush

After harvesting, let the block rest for a few days.

Keep the block in the bag and continue misting the cut area lightly. A second flush may grow from the same opening or nearby.

Second flushes are often smaller than the first, but they can still produce a nice harvest.

Mushroom-Specific Growing Tips

Blue Oyster Tips

Blue oysters are usually one of the fastest varieties to fruit.

Best temperature: 55–70°F
Humidity: Moderate to high
Fresh air: Very important

Harvest blue oysters when the caps have opened but the edges are still slightly curled downward.

If the caps flatten completely or start curling upward, they are getting mature and should be harvested soon.

If the stems are long and the caps are small, the mushrooms need more fresh air.

Snow Oyster Tips

Snow oysters produce bright white clusters and like consistent humidity.

Best temperature: 60–72°F
Humidity: Moderate to high
Fresh air: Important

Harvest when the caps are open, smooth, and fresh-looking.

If the caps look cracked, dry, or yellowing, the kit may be too dry. Mist more often and move it away from heaters, vents, or direct airflow.

Italian Oyster Tips

Italian oysters are strong, productive growers and can produce large clusters.

Best temperature: 60–72°F
Humidity: Moderate to high
Fresh air: Very important

Harvest when the caps are broad and open but before the edges curl heavily upward.

If the cluster gets very large and the edges begin drying out, harvest it rather than waiting longer.

Lion’s Mane Tips

Lion’s mane grows differently from oyster mushrooms. It forms a white, shaggy ball instead of caps and stems.

Best temperature: 60–70°F
Humidity: High
Fresh air: Gentle but consistent
Cut size: Smaller opening is best

Harvest lion’s mane when it is full, white, and has visible shaggy teeth.

Do not wait until it turns yellow, dry, or overly soft.

If lion’s mane looks dry or yellow, increase humidity.

If it grows coral-like or stretched instead of dense and fluffy, it may need more fresh air.

How Often Should I Mist?

Most kits should be misted 2–4 times per day.

Mist more often if:

  • Your home is dry
  • The kit is near heat
  • The mushroom surface looks dry
  • The block is pulling away from the bag
  • Baby mushrooms stop growing

Mist less if:

  • Water is pooling inside the bag
  • The mushrooms look slimy
  • The block stays overly wet

The goal is steady humidity, not standing water.

Signs Your Kit Is Too Dry

Your kit may be too dry if:

  • Mushrooms stop growing
  • Caps crack or dry out
  • Lion’s mane turns yellow early
  • The cut area looks dry every time you check
  • The block shrinks away from the bag

Move the kit away from heaters, vents, fans, or direct sun and mist more often.

Signs Your Kit Needs More Fresh Air

Your kit may need more fresh air if:

  • Oyster mushrooms grow long stems with small caps
  • Mushrooms look stretched or leggy
  • Lion’s mane grows coral-like instead of dense and round
  • Mushrooms appear to be reaching outward dramatically

Move the kit to a more open area with better airflow. Do not keep it sealed in a cabinet, closet, or airtight tub.

Frequently Asked Questions

Do I have to open the kit on the date written on the box?

No. The date is an estimate. Always check the block first. Only cut open the bag once the substrate looks fully colonized and mostly white.

What does fully colonized mean?

Fully colonized means the mushroom mycelium has grown through the substrate. The block should look mostly white and feel firm. It should not have large loose brown sections.

What if my kit is not ready by the estimated date?

Wait a few more days. This is normal. Cooler temperatures can slow colonization.

What if I opened the kit too early?

Keep it clean, humid, and in indirect light. It may still finish colonizing and fruit, but opening too early can increase the risk of drying or contamination.

How long after cutting the bag will mushrooms grow?

Most oyster mushrooms begin pinning within a few days to about a week. Lion’s mane may also begin forming within several days, depending on conditions.

How many harvests will I get?

Most kits produce one strong first flush and often a smaller second flush. Results vary depending on humidity, temperature, airflow, and how well the kit is cared for.

Do mushrooms need sunlight?

No direct sunlight is needed. Bright, indirect light is best.

Can I grow the kit in the dark?

A completely dark area is not ideal. Mushrooms do not photosynthesize like plants, but they do use light as a signal for proper growth direction.

Can I grow the kit outside?

We recommend growing indoors where conditions are easier to control. Outdoor growing can expose the block to bugs, drying, temperature swings, and contamination.

Is white fuzzy growth normal?

Usually, yes. White fuzzy growth is often healthy mushroom mycelium. On oyster mushrooms, fuzzy stems can also mean they want more fresh air.

What if I see green, black, pink, or orange mold?

Do not eat mushrooms from a contaminated kit. Move the kit away from your living area and contact Tahoe Mushroom Company with photos.

When should I harvest oyster mushrooms?

Harvest when the caps are open but before the edges curl strongly upward. The mushrooms should look fresh, firm, and hydrated.

When should I harvest lion’s mane?

Harvest when it is full, white, and shaggy with visible teeth. Harvest before it becomes yellow, dry, or overly soft.

Should I cook the mushrooms?

Yes. We recommend cooking all mushrooms before eating. Oyster mushrooms are great sautéed, roasted, added to tacos, pasta, ramen, eggs, stir fry, or soups. Lion’s mane is excellent sliced into steaks or torn into pieces and pan-seared until golden brown.

What do I do with the block when it is done?

After your kit is finished producing mushrooms, the remaining substrate can be composted or mixed into garden soil. Sometimes spent blocks will even produce surprise mushrooms outdoors if conditions are right.
