Grow Guide for Special MycoPots² Grow Kit


03/10/23: We now have the option of ‘No Gloves’ as well as offering an Enhanced kit version which includes 1500mL of Perlite


Step 1: Inoculation of Sterile Cylocybe Special Substrate

Work in a small, clean and draught-free room. We always recommend working within a Still-Air Box when completing inoculations of any product.

Cylocybe Special MycoPots sealed in bag with wipes and needles

Make sure you’re showered with fresh clothes. Clean your hands and forearms with the blue Clinell wipes, then fit your gloves and face mask securely.

Prepare your chosen gourmet mushroom spore/culture syringe for use by screwing in a new sterile needle.

Remove your MycoPots from the box. They are now exposed to the open air and potential contaminants – this is where working within a SAB will greatly reduce your chance of contamination.

Clean the grey rubber injection ports on the lids of the MycoPots with a green Clinell wipe. Don’t touch or try to remove the white air filter strips – they are essential.

Inject 0.5ml of your gourmet spore or culture solution through each injection port – Take care and do not add any more than 1ml to each MycoPot.

If you have any solution left and want to store it – flame sterilise the needle until red hot, leave it a few seconds to cool before putting the cover back on and then keep the syringe with needle attached in a cool, dark place – a drawer is ideal. Before using it again, flame sterilise it another time for good luck.

Step 2: Colonisation of Cylocybe Special Substrate

Mycelium is living and needs to breathe, so don’t ever store your MycoPots in an airtight container. The cardboard box they arrived in is an ideal place to now store your colonising MycoPots to keep them clean.

Temperature is so important for achieving good colonisation results. Being too hot (above 26°C) or too cold (below 20°C) may result in contamination or slow to no colonisation growth.

Stay between 20-26°C and try to maintain aa comnsistent temperature, ie. don’t let the temperature go up and down too much.

Avoid heat mats please! The warmth is not spread equally which may create excessive condensation, leading to water build-up and an easy pathway for contamination to enter your MycoPots. Consider building or buying an incubator if you’re struggling to maintain these temperatures – it’s way cheaper than keeping your home heating on all the time and gives much better results too.

At 26°C, in optimum conditions, it will generally take 2-3 weeks for the substrate to reach full colonisation or around 4-5 weeks at room temperature – but this does depend on other factors like genetics, etc. and nature being unpredictable!

Step 3: Dunking for Humidity and Hydration

When the substrate is fully colonised i.e. completely covered in white mycelium, you are ready to use a method called ‘dunking’ to prepare for fruiting. Do not ever take the lid off your MycoPots before full colonisation (if the dry vermiculite layer on top isn’t covered in mycelium, this is okay! You are just looking for the dark substrate underneath to now be completely white).

Fill a container with water deep enough to submerge your colonised substrate (known as a ‘cake’) in. Open your MycoPots and remove the colonised cakes – they will be solid blocks. Place them in the water and you can use something like a plate to weigh the cakes down to stop them floating, as you need them to be fully covered in water at all times. Put a lid on the container or cover it to keep everything clean. Leave your cakes submerged like this for anything between 6-24 hours.. depending on how much patience you have! But obviously – the longer you leave them, the better your results will be.

Step 4: Perlite for Maximum Humidity and Hydration

If you didn’t opt for the Enhanced version of the kit, skip this step.

Pour your perlite into a strainer and rinse under a tap until it’s soaking wet. When it stops dripping, pour it all into the provided XL Grow Tent. Please cover your mouth and nose when working with perlite – it’s dusty and nasty to work with (take it from us).

Step 5: Place Cakes into Grow Tent(s)

If you’re using perlite, cut a piece of tin foil slightly larger than your cakes and place this on top of the perlite so the cakes won’t touch it – don’t ever have cakes sitting on damp perlite.

After your cakes have finished dunking, take them out of the water and give them a rinse under a tap. Allow excess water to drain off and then carefully place them into your grow tent(s).

Make sure to fold over the top of your tent(s) to keep the humidity in and the dusty nasties out. A little tape might come in handy if it’s not staying closed.

Step 6: The best bit… Fruiting your mushrooms!

Maintain a temperature just below your incubation temp for this fruiting stage, somewhere between 20-22°C tends to be great for many popular species. When the temperature is right, essential levels of humidity will naturally build up inside the grow tent from the water you just allowed to soak into the substrate.

You should not mist this kit, unlike some other grow kits you may have seen or used before. The only time you should remove your tent is when you’re ready to harvest your mushrooms – removing it even for a few seconds before this is enough to lose humidity and cause growth defects (aborted pins, caps breaking, etc).

Humidity and FAE (fresh air exchange) are extremely important for pinning and healthy mushroom development, as is temperature and light. They will all need to work in harmony.

We suggest cutting a 1cm slit through both sides of the tent, near to the top and placing an electric fan somewhere in the room on low setting. This will create a gentle air current inside the room which will increase FAE inside the grow tent. Your mushrooms will also need light to grow – we recommend indirect sunlight or a 6-7000K LED or fluorescent light a couple of feet away.

If you notice the inside of your grow tent looking dry, there are a few things which can cause this: The environment is too cold so humidity is not developing inside your grow tent, the fan is too close, the slits you cut in the tent are too big (cover excess with tape), grow lights are too close and drying out the substrate… Observe what’s happening and adjust your setup as required – fantastic results depend on it.

After around 3-7 days you’ll begin to see lots of tiny white dots – these are hyphal knots which will develop into primordia, aka mushroom pins… the exciting part! It’ll then only take 4-5 days for them to grow into fully mature mushrooms ready for harvest.

During this time, they’ll let you know if something isn’t quite right – fuzzy mycelium at the base of the mushrooms and/or thin stems are an indication that more FAE is needed so increasing the fan speed or length of the cuts on the bag might be something to try.

Don’t worry about any mushrooms growing around the sides and bottom of the cakes, you’ll still be able to harvest them. If you want to give your mushrooms more room to grow next time, consider using a fruiting chamber.

When the veil beneath one of your mushroom caps is about to tear off, this is when you should harvest your first flush. If you don’t get there quick enough, spores will begin to drop from your mushroom caps and make a mess!  It’s best to cut the mushrooms off with a clean scalpel or knife, you can also just pull them off but be careful not  to damage the substrate too much.

After you’ve harvested all the mushrooms from your first flush, you should dunk your cakes again to rehydrate them for round 2! Remember to rinse them and allow excess water to drain off before placing back into your grow tent. It’s really important that you dunk your cakes between each flush for best results. If using perlite – you should also pour it into a strainer again and rehydrate it whenever you’re dunking your cakes.

If you’ve taken good care of your grow kit, you should achieve multiple flushes of beautiful mushrooms before the nutrients are all used up.


Thanks so much for ordering our grow kit. We hope you love using it and reap the rewards.
