How to Use the    SHROOMBOX

 

Simple Step-by-Step Growing Guide

The SHROOMBOX is designed to make growing mushrooms easy, whether you're cultivating culinary, medicinal, or dung-loving varieties.

 

Step 1: Start with a Fully Colonized Block

Before using your SHROOMBOX, make sure you have:

  • A fully colonized grow block OR

  • An all-in-one grow bag ready for fruiting

Do NOT place uncolonized substrate into the SHROOMBOX.

Once fully colonized, transfer your block into the SHROOMBOX to begin fruiting.

 

Step 2: Set Your Temperature

  • The SHROOMBOX does not control temperature internally

  • The display shows temperature for monitoring only

Adjust the room temperature to match your mushroom’s ideal fruiting conditions.

 Important:

  • Every mushroom species has different temperature needs

  • Always look up your specific species

*Pro Tip: The internal light bar (on max setting) can raise temps by ~2–4°F

 

Step 3: Set Humidity (Pinning Phase)

Once your block is inside:

  • Set humidity to 95%–99%

  • Set variance/difference to 3–5%

This means the humidifier will turn back on when humidity drops a few % below your target.

 Optional:

  • Add ≤ 1" of perlite at the bottom to help retain moisture

  • Not required, but helpful

Always place your block on the grow platform
→ Never let it sit directly in water or perlite

 

Step 4: Set Fresh Air Exchange (FAE)

  • Turn the air pump (front right) all the way up

 This provides the fresh air mushrooms need during fruiting

 Exception:

  • If growing COâ‚‚-loving species (like antler-style reishi), reduce airflow

 

Step 5: Set Exhaust Fan Cycle

Use the smart controller:

Recommended starting setting:

  • 20 minutes OFF

  • 5 minutes ON (looping)

This helps regulate COâ‚‚ levels during fruiting

You can adjust this higher or lower depending on your grow

​

Step 6: Set the Light Cycle

  • Set the internal light bar to run 12 hours ON / 12 hours OFF

Default setting:

  • 08:00 → 20:00 (8 AM – 8 PM)

 Important:

  • The timer uses a 24-hour (military time) clock

  • If adjusting the schedule, be sure to input times in 24-hour format

 Example:

  • 8 PM = 20:00

  • 6 PM = 18:00

 

Step 7: After Pins Form

Once you see pins (baby mushrooms):

  • Lower humidity to 90%–95%

  • Set variance to ~5%

Keep fresh air exchange strong:

  • For species like Lion’s Mane & Oyster:

    • You can run the fan continuously

    • BUT only if humidity stays stable

 If humidity drops too much:

  • Switch back to interval mode

 

Step 8: Maintain Water Levels

  • Check the humidifier reservoir every 2–3 days

  • Keep it filled until mushrooms are fully developed

 

Step 9: Harvest & Reflush

  • After harvest, your block can produce multiple flushes

To continue growing:

  • Rehydrate the block between flushes

  • Return it to the SHROOMBOX

 Cleaning between flushes is optional, not required

 

That’s It! You’re now growing mushrooms the easy way.

The SHROOMBOX is designed to handle the environment—so you can focus on enjoying the process.
