How to Grow Magic Mushrooms using a Growkit

Growing magic mushrooms is remarkably simple. Our kits include a substrate of perlite and vermiculite with added mycelium, the source of the mushrooms. Activating and starting their growth is a breeze. Read on for a complete guide.

Different mushroom strains vary in ease of growth, potency, and yield. They originate from diverse regions worldwide, leading to varying shapes upon maturation.

Growing Magic Mushrooms | Essential Conditions:


Lighting plays a crucial role in the growth of magic mushroom mycelium. It’s essential to manage the amount and quality of light they receive. Direct exposure to light should be avoided. Sunlight or a regular white bulb can be used, but they should never directly illuminate the substrate. Determining the right amount of light can be tricky since mushrooms naturally thrive in forests where they spend considerable time in darkness. If using sunlight, place the mushrooms beside a window with open curtains, ensuring they don’t receive direct sunlight. For artificial lighting indoors, position the light source in a way that prevents direct exposure to the substrate.


Maintaining proper humidity is crucial to activate the mycelium, the foundation from which mushrooms grow. To achieve the right humidity level, use a small greenhouse propagator. Hydrate the substrate cautiously with bottled, osmosis, or distilled water—never use tap water. Slowly add water to ensure even moisture distribution, and remove any excess water once the substrate is fully saturated. Accumulated water at the container’s bottom can lead to fungal issues.


Our mushroom kits include a bag that serves as a propagator, but for optimal results, consider investing in a dedicated greenhouse propagator like the Propagator With Heater By Neptune. To activate the mycelium, maintain a consistent 90% humidity within the propagator for at least two days. This involves adding additional water to the propagator’s bottom, not the substrate container, using osmosis, distilled, or bottled water. Alternatively, keeping the propagator lid closed intensifies humidity. After the initial two days, decrease humidity to around 70% by adjusting the small side windows on the propagator.


Maintaining the right temperature is crucial. Mushrooms typically flourish between 21 and 24°C. For optimal production, position the propagator within this temperature range. In colder environments, consider using a heated propagator or placing a heated blanket beneath the propagator. Mushrooms grown below 21°C tend to grow slower and yield fewer mushrooms. Once the mycelium becomes active, there’s a limited window for mushroom production.


Maintaining hygiene and a sterile environment is crucial for successful magic mushroom cultivation. These mushrooms are sensitive and require a clean environment. Always handle them with latex gloves and preferably wear a face mask to prevent contamination. Avoid introducing foreign elements like smoke, deodorants, or sprays in the growing space, as they can disrupt proper growth.

Providing adequate lighting, humidity, and temperature along with a clean environment will ensure abundant psychedelic mushroom growth. GB The Green Brand offers comprehensive kits for growing magic mushrooms, including necessary items like heated mats, thermo-hygrometers, and complete mycological study kits.

Between 7 to 14 days, you’ll notice the initial mushrooms emerging. Afterward, they’ll continue to sprout all around. Regular checks may reveal their steady growth, increasing by a few centimeters each day. Harvesting might be possible in 3 to 4 days, followed by a drying period before further examination.

To harvest, wear gloves and gently twist and pinch the mushrooms between your fingers; they should come off easily. They’re delicate, and touching them might temporarily darken the area, which is normal and not a cause for concern about contamination or decay.

After harvesting, don’t discard the container. The mycelium might remain active, potentially producing another batch in a few days. Under ideal conditions, you might even harvest mushrooms three or four times from a single container.
