Cylocybe Special Grow Kit (v2.0)


You won’t find a kit like this anywhere else.

V2.0 / June 2019 – Now includes even more perlite and a larger humidity tent for better airflow, hydration and ease of use!

Have you already tried the BRF based PF-Tek grow kits? Want to step it up and try something new? Then the Cylocybe Special Grow Kit is most definitely for you.

Using similar techniques to the advanced cultivators in the scene, we have managed to create an easy kit which has fewer steps, supports even more mushroom species and most importantly – bigger flushes!.. This is why we call this kit special.

This pH balanced mix of grain, coffee, coir and gypsum packs a nutrient punch for many species of mushrooms!

Simply inject 1ml of gourmet spore or liquid mycelium into each of the six injection ports (totalling 6ml) and wait for it to colonise fully.

When it’s finished, remove the lid and place within the humidity tent to fruit.  Our grow guide explains it in more detail!

  • 1.2L Substrate for a huge mushroom yield
  • Organic Rye Grain Substrate with added Coir, Gypsum and Coffee
  • Injection Port and HEPA-Filtered for ultimate contamination resistance
  • HEPA-Filtered Humidity Tent(s) for each MycoBox
  • Hygiene Kit includes sterile gloves, face mask, alcohol wipes, hand wipes
  • Perlite to create high humidity
  • Full Instructions (or you can just click on the ‘Grow Guide’ tab to see here!)

Can take up to 5-6 weeks to fully colonise in optimum conditions.
Does not come supplied with a spore or culture syringe.
Some wood-loving species like Shiitake will fruit on this substrate.

Grow kits are currently only available for customers in the United Kingdom.
Product is made fresh to order – please allow for a 1-3 day dispatch time.
Only for use in cultivating species which are legal to grow – research the law.

You will need:

  • Your chosen gourmet spores or liquid mycelium syringe
  • Cylocybe Special MycoBox(es)
  • A lighter to sterilise the needle (Only needed if working with multiple MycoBoxes and haven't purchased extra sterile-packed needles)
  • Sterile gloves (as supplied with kit)
  • Face Mask (as supplied with kit)

With this product, it's unnecessary to work within a Still-Air-Box (SAB) or any other purpose built clean room environment - although it certainly won't do any harm!

1. Take everything to your 'lab'

An ideal room to use as your lab will be draft-free, such as a small cupboard maybe. Kitchens and bathrooms are generally not suitable because of the increased risk of mould - but the fitted injection ports and HEPA-filter on the MycoBox(es) should still protect you in any case.

Take everything you will need into your lab at this point - keep air currents to an absolute minimum (doors closed!) to lower the odds of a contaminant spore dropping onto the self-healing injection port directly prior to syringe inoculation of gourmet spores or liquid mycelium!

Remove the MycoBox(es) from the bag(s) so that you can later grab them with ease.

2. Cleanliness

Take the time to ensure you are completely clean - have a shower, brush your teeth and change into fresh clothes.
Before you begin the inoculation process, take your face mask out of the bag and secure it tightly to your face. Then, make sure your hands and forearms are clean - you can wipe them with the included Clinell wipes and let them completely air dry first or you'll struggle to put your sterile gloves on!

3. Inoculation process

When you are ready to inoculate your substrate, wipe the MycoBox with the supplied Clinell Chlorhexidine wipes - it's best to wipe every surface of it and then use a new wipe to clean the injection ports (wait until the ports have dried before piercing them!). The MycoBox has been sterilised but these steps are just to ensure that you are cleaning away any possible risks of contamination that could have landed during handling.

Fit your needle on to your syringe and swiftly pierce your needle through each self-healing injection port - inject approximately 1ml into each port (totalling 6ml).

If you are inoculating more MycoBoxes with the same syringe, make sure to flame sterilise the needle until it is glowing red hot between MycoBoxes. This will reduce any chances of cross contamination. Just remember to leave the needle to cool down for 5 - 10 seconds, or you can just squirt a little solution through it to cool it quicker!

DO NOT wipe a needle with an alcohol pad and expect it to be sterile. Alcohol merely sanitises, it does not sterilise. Always flame sterilise.

4. Light and room temperature

Now it's time to leave your MycoBox(es) in a safe place to colonise. It is recommended, although not necessary, to leave colonising substrates in a room with indirect sunlight or light from a flourescent bulb.. but many growers just leave them in a dark cupboard - so don't worry about that too much. Just make sure the sun isn't beating down on them!

Regarding heat, many species do love very warm climates during colonisation but it can be a balancing act because so do bacteria!

If your mycelium is going strong, it can outrun many types of bacteria and you will never know they were even present..

If you can manage to keep the colonising MycoBox(es) somewhere between 18C and 26C, then it will be just fine. 26C is noticeably faster than 18C, but if you have a cold house or flat don't worry about it.. it will get there. We have even managed it in a cold Scottish 10C flat!
If you are determined to get a warmer environment for faster colonisation times, we strongly advise against heat mats as they will just dry out the bottom of your substrate. You will need something a bit more equal on all sides. A warm cupboard above a fridge.. Near the water boiler..? There will always be little hot spots around your home that will do the job.

5. Colonisation

Generally, you will start to see mycelium growth after 5-10 days.

It will normally take around 5-6 weeks for your MycoBox(es) to fully colonise in optimum conditions (i.e. to be completely covered in white mycelium) but again, this can take a bit longer depending on a range of factors such as temperature, genetics, whether from spore or culture syringe etc..

When they have reached full colonisation, it is highly recommended that you leave them for another week to allow the mycelium to consolidate - basically, to make sure the mycelium has a full hold on the Special Substrate(s).


Now you are ready to grow some mushrooms!

It's as simple as placing the MycoBox in the humidity tent with damp perlite and taking off the lid..

You will need:

  • Bag of perlite (supplied with kit)
  • A sieve/strainer
  • Humidity tent(s) for each of the MycoBox(es) (supplied with kit)
  • A spray bottle to mist your cakes with water

1. The first step is to rinse the perlite to get rid of all the excess dust. Please wear a face mask or cover your mouth and nose in some way when working with perlite. Get yourself a sieve or strainer (of course with holes smaller than the size of the perlite) and empty the perlite into it. Rinse under a running tap until you can see all of the dust is gone and that the perlite is fully soaked, turn the tap off and shake off some of the excess water.

2. Immediately pour all of the damp perlite into your humidity tent(s) - this will create the humid environment mushrooms love.

3. Place your MycoBox on top of this perlite layer and remove the MycoLid.

4. Fold over the top of the bag and either leave it as is (if the opening is pointing downwards, no dust/mould particles can fall in there) or if you prefer - you can put some paper clips or pegs on there to hold it shut.

5. You will now need to mist your substrate casing with water regularly to ensure constant hydration. Mist directly until the casing layer glistens with moisture and when you can no longer see the glisten on them, it's time to mist them again.. Misting 3-6 times a day is pretty common for ultimate results.

The evaporation of moisture from your substrate(s) is the trigger for mushroom pins to form and grow - this is why the humidity tent(s) we supply in our grow kit have lots of filters to provide clean air exchange. If you do not mist regularly to replace this evaporating moisture, you will break the cycle and you will have a very bad harvest.. Simple as that.

You must continue to mist throughout the full growing process - when you see pins forming and whilst your mushrooms are growing.. remember mushrooms are 90% water, they need all that extra moisture!!


When your mushrooms are ready for harvest, you can either cut them off with a knife/scissors or some people prefer to just twist and pull their mushrooms off - but be aware this can sometimes pull some of the substrate off with the mushroom, so it's not the best method.

When you have harvested all of your mushrooms, you should heavily mist your substrate often over the next 24-48 hours for more fruting!

...Have fun!
