How do I store the grow kit?

Do not store your grow kit longer than 2-3 weeks

We recommend starting your mushroom grow kit right away and begin the growing process. If you decide to grow later, do not store your grow kit longer than 2-3 weeks after the production date.

Store in a cool place

Always store the mushroom grow kit in the refrigerator (2°C to 4°C). The production date is printed on the cardboard box and includes the two digits of the week number.

Avoid contamination

Make sure your fridge is clean and free of bacteria, yeasts and other sources of contamination. To be safe, pack the culture kit in a clean plastic bag and seal it tightly.


  1. 1

    Wash your hands thoroughly and clean the outside of the growkit with a dry cloth. Remove the lid and save it for step 2

  2. 2

    Fill the growkit to the edge with lukewarm water (20°C), put the lid back on the growkit and let it soak for 5 minutes.

    Important: never soak the growkit for more than 1 hour!

  3. 3

    Remove the lid from the growkit and drain the water well. Let the growkit drain for 10 seconds.

  4. 4

    Place the growkit in the growbag and fill the growbag with a cup (200-250ml) of lukewarm water (20°C). Then fold the top of the bag and close it with 2 paperclips.

  5. 5

    Place the growkit in a place with 20-25°C average room temperature. Make sure that the growkit is not in direct sunlight, not under a lamp and not near a radiator/heat source.
    Important: the bag must remain closed until the first pinheads form. Until then the CO2 content and humidity inside the bag should be as high as possible.

  6. 6

    When the first pinheads* are visible, let some fresh air into the growbag on a daily basis (for a few minutes) and then moisten the growkit with a misting bottle.
    *Pinheads are the first visible forms of tiny mushroom caps. It can take 10 to 20 days for the first pinheads to be visible.

  7. 7

    The mushrooms can be harvested just before the membranes on the bottom of the cap open up. While harvesting gently grasp the stem and turn it left/right. When the mushroom becomes loose, pull it out as carefully as possible.
    Important: the mushroom must be completely removed so that there is room for a new one.

  8. 8

    Congratulations, the harvest is complete. It is now possible to grow a new flush of mushrooms by repeating steps 1 to 7 again.

Read the following do's and dont's for a successful grow.

Despite the fact that mushroom grow kits are easy to grow and reasonably idiot-proof, we have listed the most important points for you. Such as temperature, light, humidity, the first mushrooms and the growth cycle.


The ideal temperature for mushrooms to develop is 24°C. Do not have the temperature drop under 20°C and not exceed 29°C. To keep the temperature from dropping under the 20°C, you can use a Thermo Heatingmat to maintain the ideal temperature. A thermo mat is a must-have in the winter or colder regions of the world.


The magic mushroom kit only needs light for the mycelium to ‘understand’ it has reached the surface. Only then, mushrooms will grow. A few hours of fluorescent/artificial light or indirect sunlight a day is more than enough. Direct sunlight kills the mycelium, so avoid the sun to shine directly on the grow kit.


The day the first pins show you begin with misting. Open the grow bag by removing the paperclip. Do not spray directly on the cake but spray one time against every side of the bag. So you mist once a day, four sprays. Misting also vents fresh oxygen inside the bag. Right after misting, close the bag again with the paperclip.

Frequent air exchange (FAE)

Keep the grow bag closed untill you see the frist pins, CO2 should be as high as possible to induce pinning. After the pinning stage you can open the bag 1-2 times a day to let in fresh air. Open and close the bag and push out the air and let is some new.

The 1st shrooms!

If the cultivation conditions are optimal, you can expect the first small mushrooms (the pins) to appear between 10 and 20 days. This also depends on the strain. Some cubensis strains grow slower than others. to reach maturety it can take up another week. A full grow cycle can take up to 4-5 weeks.


The mushrooms come up in groups. A growth like this is called a flush. You can get more than one flush out of a kit. The first two flushes are the largest. When more flushes come, they will be smaller than the previous one.

Picking and Harvesting

Mushrooms should be picked when the veil between the hat and the stem is about to or has just torn. Don’t wait longer or the mushrooms drop their spores. Pick the mushrooms that are ripe and let the others continue to grow. The other option is to remove all the mushrooms and start a new flush.

How to pick your mushrooms:

  • Use surgical gloves or disinfect your hands, wrists and arms. 
  • Remove the mushrooms from the cake by taking hold of the base of the mushroom between thumb and index finger.
  • Rotating your hand clockwise slowly, until the mushroom lets go.

Do not pull out the mushrooms. This would risk damaging the mycelium and killing it. When most of the larger mushrooms have been picked, also pick the smaller ones and the pins as well.

Mushrooms that grow from the sides

Mushrooms grow where the light reaches and where there is little penetrating resistance. Because the cake has light shining on the sides, the mushrooms might also grow there. You have a few options:

  • Darken the sides of the kit by putting it in the cardboard box.
  • Spray the top soil a bit to stimulate more growth on the top
  • Do nothing and let them grow


After all the mushrooms are harvested, you prepare the kit for the next flush. Disinfected your hands or use gloves; take the grow box out of the grow bag.

  • Fill the container with lukewarm water (20°C)
  • Take the lid use it to close the container.
  • Let it soak for 5 - 20 minutes.
  • Remove the lid, and drain the water
  • Place the growkit in the growbag and fill the growbag with a cup (200-250ml) of lukewarm water (20°C)

This is called the soaking process. Water will now soak through the cake, preparing it for the next flush.

During the soaking you can hang the grow bag with micronfilter upside down to dry.  Many growers prefer to use new and unused grow bags after every flush.

Next Flush

To continue, follow the same steps 2 – 7 as before when you started the process for the first time. Several days later, a new flush will appear. You can get at least 2  flushes out of a grow kit. The first flush often is the biggest.

The End

When no more mushrooms grow out of your grow kit after the second flush for at least 5-6 weeks, or when the grow kit turns green, red, grey or yellow; the grow kit can be disposed of.  The change in color is a sign that the grow kit is contaminated with another fungus or bacteria. No more mushrooms will grow out of the mushroom grow kit and the grow kit should be thrown away in the garbage outside or in your garden.


When you are too late picking the mushrooms, they will drop their spores. The cake and the mushrooms will turn black/purple (some other cubensis strains red/brown) because of the spores. This is not really a problem; it just doesn’t look very pretty.

When mushrooms release their spores, they also start to degrade, and the active ingredients are breaking down. Mushrooms will lose some of their potency.

surprising results Review by Ralfy
From the first two flushes I got 298g but as I had to go away for 10days I thought what the heck, lets put the kit into the fridge. So when I reanimated the kit with warm water I got the biggest flush of 244g alone! So I kept putting the kit into the frigde between the flushes so I got totally 7 flushes 723g. I dont know it there would be same results without the fridge but I guess that cold shock was somehow contributing to the growth. Just my 2 cents.. (Posted on 10/16/2023)
Everything good Review by Zen
I have got the kit very quickly and stored in the dark by two weeks (because I was out of home). Then I started to maintain with water etc. After three weeks I have got shrooms about 0,5 kg (48g dried). It was first harvest. I don't know what will be the next one but the first one is quite good and I am happy. Before this GetMagic kit I used Mondo Kit and it was awesome (more than four harvest). (Posted on 10/11/2023)

Psilocybe Cubensis B+ Review by nyctophile
All good, the kit came in about 2 weeks without any problems. I started noticing the first small mushrooms appear after about 2 weeks. On my first flush, so far so good. (Posted on 7/12/2023)
The best thing that happened to me since I can remember Review by Thiago
I bought this kit because of my wife, who has a chronic sleeping issue for many years, as we thought it might help her with that.
The kit worked as intended, we took proper care during the growth period, and were able to harvest a good quantity after 20+ days.

It seems my wife have some sort of resistance for now, and it had just a mild effect on her. On myself, it was a very different story, as using this mushroom completely changed the way I see the world and my own life, not to mention that the day I used it, I had the most powerful experience of my life.

We want to try again with her, and I definitely gonna further my experience with it.

Very grateful for the team that provided this wonderful experience.
I will not go into more detail, because this might get too big, but I higly recommend it.

The delivery was on time, and the customer service is the best ever.

third Review by Roberta
Nice product (Posted on 3/25/2023)
Fast shipping and good first flush Review by floffy
The whole payment/shipping experience was really nice. My first flush was only few very large mushrooms. Trying to optimize the environment to get manny small ones with the next flush instead. Excited to see how many more there are gonna be. Overall very happy! (Posted on 3/3/2023)
probably the best so far Review by jack
i already had another brands and GetMagic imho have best bags and substrat, their manual is best telling you to leave glass of water on the bottom of the bag which distribute heat and provides perfect humidity. when fruiting bag can be slightly opened as more oxygen may give more yield. heating matt or warm palce with daylight strongly recommended.

this is my honest opinion and I'm not going to get paid for this or use promocode, I can even pay more for kits as good as GetMagic™
please;-P (Posted on 12/23/2022)
