Growing Magic Mushrooms in 7 simple Steps – Mushroom Growkit Manual

Below you find a short but detailed 7-step-manual for growing psilocybin containing magic mushrooms with a stealthbox grow kit. If you are too lazy to read everything, there is a quick bullet-point-guide at the end of the growkit manual. If you want to see pictures of all the steps, wait for my next blog, which will be a grow diary of my latest harvest! You will find the blog here.

1. Get your Magic Mushroom Growkit

The first thing that you need to do obviously is: getting your own stealthbox! Sirius offers several different strains of psilocybin mushroom growkits.

You can either buy them in one of our stores (Maastricht / Roermond) or order them online (check if stealthboxes can be delivered to your country first!). Once you’ve received your stealthbox, we recommend that you activate it as soon as possible. If you need to wait, store it at a temperature of 10 degrees Celsius until you can activate it. Don’t wait too long, because our stealthboxes are all fresh, and the longer you wait, the more it can influence your harvest. 

2. Prepare yourself and your surroundings

Before you activate your growkit, you want to be as well prepared as possible. Some things you need include:

  • Stealthbox growkit
  • Mushbag with 2 paperclips (included in the stealthbox!) 
  • Heatmat & grating (see step 3.1)
  • Latex gloves; Disinfection spray (if possible: isopropanol) 
  • Spray bottle
  • (Aluminum-) foil (see step 4.1)

You need to work in a clean and hygienic surrounding. Every possible source of contamination can worsen the conditions inside your kit. Make sure to disinfect the space you want to grow your mushrooms and wash your hands. Wear latex gloves, bend your hairs together and don’t wear fuzzy clothes. 

You should place the kit at a spot where it is warm, preferably 20 to 25 degrees Celsius. It should receive some daylight, but do not expose it to direct sunlight! Otherwise, it will dry out. Make sure that you are able to take care of the kit every day for the next 2-3 weeks. 

3. Activate your stealthbox

When you activate your mushroom growkit for the first time, you just need to take it out of the box, open the lid, and place it inside the mushbag. 

Wash the lid with clean water, dry it, and keep it! You will need it again later. Spray the inside of the mushbag with tap water, but not too much! The mushroom growkit itself should not get wet, only the inside of the bag.

Let the bag open for a few minutes to make sure some fresh air gets inside before you close it. To close it, you just fold it a few times and attach the paper clips.

3.1. Heatmat and Grating

If you want to be 100% sure that you receive a big yield, you should get a mushroom-heatmat. It keeps the temperature below your growkit optimal, making sure the mycelium can fully develop into big juicy shrooms. Make sure to not directly place your growkit on the heatmat, but use a grating, so air can flow below the growkit and it doesn’t dry out. 

Sirius Tip: You can use filter tip booklets or empty (cigarette-) paper packages for this! There is no need for a large grating, as long as there is a tiny gab between the growkit and the heatmat, so that air can flow.

4. Take (good) care of your stealthbox

Now your kit is activated and will produce mushrooms for you! But you still need to take some care of it. Every day, you should open the bag for a few minutes to let some fresh air inside. Then you spray tap water on the inside of the bag (not too much!) and close it again.

Remember to wear gloves and disinfect your surroundings! If you see the first pinheads of mushrooms, you can leave the bag open for a longer time. This step usually takes 1 to 3 weeks.

4.1. (Aluminum-) foil

Check your kit regularly! It is possible that you notice shrooms growing inside the mycelium cake on the side of the box (so not on the surface). If that is the case, you just need to put some (aluminum-) foil around your growkit so that no light hits the outside of the box. Make sure to only cover the side of the box, not the bottom, so the heat below does not get isolated from your kit. You can also do this in preparation if you want to be extra sure! 

5. Wait for your magic mushrooms to be ready

Eventually you will start to see the first shrooms appearing on the surface of the growkit. You will be surprised how fast they turn big! At this point, you should carefully monitor how your shrooms grow every few hours.

If you wait too long before you harvest them, the mushrooms will produce spores which can contaminate your kit. This is not bad for the mushrooms, but it is less likely that your kit is now able produce a second flush of mushrooms.

6. Harvest your magic mushrooms

The day has finally come, and you can harvest your shrooms! Put on some latex gloves and place the growkit on a clean, disinfected surface. Lay out a towel or some paper in a space where you can let the mushrooms dry. It should be a warm, dry room, and the place should not be exposed to direct sunlight! This could reduce the potency of your mushrooms.

Reach inside the mushbag and grab a bunch of mushrooms. Carefully harvest them with a turning movement of your hand (you don’t need any force; the mushrooms are very light and will easily come out if you turn your wrist!). Be really careful! This determines how well your mycelium stays intact for future harvests. Put the mushrooms on the towel/paper you prepared and make sure they do not touch each other.

6.1 Drying and storing your Magic Mushrooms

If you want to make sure that your magic mushrooms remain their potency for as long as possible, you should properly dry them. 2-3 days are usually enough. You can test whether your mushrooms are dry enough if you bend them: if they easily crack, producing a ‘snapping’ sound, they are ready. If they are still bending and not breaking, leave them.

When they are dried, you should put them in an air-sealed glass, so they do not lose any of their potency!

7. Reactivate your Magic Mushroom Growkit

No, the fun is not over yet! When you complete the harvesting process, you can activate your mushroom growkit again! Just let some tap water inside the kit, close it with the lid and put it in the fridge for approximately 12 hours. When you open it again, let the water out of the box, put the kit in the mushbag, and repeat from step 4. 

Have fun growing! Before you consume your magic mushrooms, you should inform yourself about the possible (side) effects! Contact the Sirius customer service or visit one of our stores! Have a nice trip!

  • Place the mushbag with the growkit inside on the heatmat (use a grating for air circulation!) in a warm room (20-25C). Do not expose it to direct sunlight!
  • Open the mushbag to let fresh air inside and spray some water on its inside every day
  • Wait until your mushrooms grow
  • Harvest your mushrooms before they produce spores
  • Dry your mushrooms (not in direct sunlight!) for a few days and store them in an air-sealed container
  • Reactivate your growkit by letting some tab water in, closing it with the lid, and placing it aside for 12 hours. Then you can start all over again!
