How To Grow Zamnesia SUPREME Mushroom Grow Kits

Growing mushrooms at home with a Zamnesia SUPREME Grow Kit is simple, fast, and designed for reliable results. Each kit contains a fully colonised substrate, meaning you can skip complicated preparation and focus on creating the right environment.

With proper care, your kit can deliver multiple flushes of fresh mushrooms with minimal effort.

What you need

  • Zamnesia SUPREME Grow Kit
  • Clean water
  • A bright space with indirect daylight
  • Optional: heat mat for colder environments
  • Clean hands or sterile gloves

Before you begin

Zamnesia SUPREME kits are ready to grow immediately, so avoid unnecessary interference:

  • Do not soak the kit before first use
  • Do not spray water during the initial phase
  • Do not place in direct sunlight
  • Avoid breathing directly into the bag
  • Always maintain clean working conditions

Because the substrate is already fully colonised, the kit naturally regulates moisture at the start.

Storing your grow kit

As Zamnesia SUPREME Grow Kits are fresh, ready-to-use products, it’s best to begin cultivation as soon as possible after receiving them.

If you need to delay the process, the kit can be stored in a refrigerator at 3–5°C. Under these conditions, it may remain usable for up to 4 weeks, although this cannot be guaranteed.

To reduce the risk of contamination, always keep the kit sealed inside a clean plastic bag while stored.

Step-by-step setup


Prepare Zamnesia SUPREME Grow Kit  

Step 1: Prepare the kit

Remove the grow kit from its packaging and keep the cardboard box for later use. Take off the lid, rinse it under clean water, and store it safely, as you’ll need it again for future flushes.


Insert grow kit into grow bag  

Step 2: Insert into the grow bag

Place the grow bag flat and slide the Zamnesia SUPREME kit inside. Fold the bag neatly underneath the container and ensure the micro-perforation sits just above the substrate, facing upward. Place everything back into the cardboard box to block side light and stabilise conditions.


Create the right mushroom growing environment  

Step 3: Create the right environment

Position your kit in a bright area with indirect daylight only. Keep the temperature between 18–28°C, with 23°C being ideal for best results. Avoid direct sunlight at all times, as it can dry out and damage the substrate.

Note: A heat mat can support the growing process in colder environments, but it won’t fully compensate for a room that is too cold.


Mushroom pinning stage  

Step 4: Pinning stage

After 1–3 weeks, small pins (baby mushrooms) will begin to form. At this stage, place the grow bag upright and do not spray water. Under the right conditions, mushrooms will continue developing naturally.


Growth and humidity control for mushroom grow kit  

Step 5: Growth & humidity control

Once the caps become visible, slightly open the grow bag to allow excess moisture to escape and prevent heavy condensation buildup. The first pinheads commonly appear within 1–3 weeks, and once caps have formed, full development typically takes around 1 week.


Step 6: Preapre for the next flush  

Step 6: Prepare for the next flush

After harvesting, fill the container with cold water to cold-shock the substrate, close it with the lid, and leave it to soak for 12 hours. Drain away any excess water and restart from the setup stage to begin another flush.


Harvesting your mushrooms

Harvest just before the veil beneath the cap begins to tear.

Waiting too long leads to:

  • Spore release
  • Reduced yield in future flushes

How To Harvest

  • Wash hands and forearms thoroughly
  • Use sterile gloves if possible
  • Gently twist mushrooms at the base (don’t pull)
  • Remove all mature mushrooms at the same time

Harvesting slightly early is better than too late.

Best practices for maximum yields

  • Keep temperature stable
  • Maintain cleanliness at all times
  • Avoid unnecessary handling
  • Monitor humidity daily
  • Harvest at the correct time

Zamnesia SUPREME Grow Kits are designed to do most of the work for you; your role is simply to maintain the right conditions and let nature take over.
