Rye Grain MycoPots³ Grow Kit

£34.95

Our classic grow kit is back and upgraded to SteriBag™

Grow almost any mushroom species you want with our complete mushroom grow kit for beginners and experienced alike.

Our classic Rye Grain MycoPots are completely sterile, inside and out and ready to inject with a gourmet mushroom culture syringe.

Your favourite mushroom species will soon consume this substrate and provide up to 3+ packed harvests until the substrate is completely shrunk and spent of nutrients! Just show it some love (and humidity!).

When we say it’s ready to inject, we mean it. SteriBag means no more wiping prior to inoculation as it’s already as clean as it can be.

All grow kit products are for UK customers only at this time, sorry.

Description

Our classic triple grow kit

Filled with perfectly hydrated (coffee enhanced) Rye Grain and Gypsum.

These three grow MycoPots are capable of delivering an impressive flush sizes between them, up to 3+ harvests if you show them extra love (and humidity!).

The inject-thru™ and new SteriBag™ system will keep all of the MycoPots safe from contaminants right up until you use the them.

Inoculation

  1. Give the SteriBag™ a quick clean with the included wipe
  2. Cut the bag along its shortest side
  3. Slide a single MycoPot out to reveal the first two Inject-Thru™ points
  4. Use 0.5ml to 1ml of a gourmet spore / culture syringe deep into each port
  5. Repeat with with the remaining MycoPots Inject-Thru™ points
  6. Discard SteriBag™ and leave the MycoPots alone in a warm place to fully colonise
  7. Follow the rest of the guide until harvest

The white HEPA filters on the lids will filter dust and mould spores and allow clean air exchange. Don’t try to remove these!
NEVER open the MycoPots before full colonisation of mycelium or the kit will be ruined with contamination.

Storage

If you cannot use your grow kit right away, we would advise that you store it in a (clean) fridge for a maximum of 2 weeks.
If you can’t store it in a fridge, don’t leave it for any longer than 1 week.
The longer you leave it, the more moisture will be lost from the substrate and if too much moisture is lost, colonisation will just not happen.

Always inoculate your grow kits as soon as you possibly can!

Advice

  • These grow kits are tailored for speed.
  • The bag the MycoPots arrive in may contain a small build up of water due to high pressure steam penetration – the distilled water is sterile and nothing to worry about.
  • Typically takes around 3-4 weeks to fully colonise in optimal conditions (incubator set to 26℃). Exact times are impossible to say as it’s dependant on genetics.
  • A gourmet mushroom spore syringe can have tens of thousands / millions of different genetics, so it can be pot luck which traits you will get. Whereas a culture syringe has predictable and pre-determined genetics.
  • Some wood-loving species like Shiitake fruit on this substrate.

Rye Grain MycoPots Grow Kit

STAGE 1: INOCULATION

For this stage, you will need:

  • Rye Grain MycoPots (supplied)
  • Surgical face mask (may be supplied)
  • Pair of gloves (supplied)
  • Alcohol wipes for wiping injection ports (supplied)
  • Gourmet spores / liquid mycelium syringe and needle (not supplied)
  • Flame lighter (not supplied)
  • Zipper bag for leaving the MycoPots in afterwards (not supplied but recommended)
Summary:

Make sure you are clean, and the room is clean and draft-free. Fit your gloves and face mask - make sure your hands are clean and bone dry before fitting them or you won't get the gloves on, trust us! Use the alcohol wipe to thoroughly clean the rubber ports built into the tubs (allow a few seconds to become visibly dry) and then pierce into each rubber port to inject between 0.5ml and 1ml. Flame sterilize the needle between each MycoPot and other kit you may have purchased (if you haven't purchased extra needles from us).Now place the MycoPots into a plastic zipper bag to keep dust and other nasties off them - leave a gap in the seal so they can still breathe! Place somewhere at room temperature to begin colonising, they will turn completely white in time, so be patient. Don't put these pots in any direct sunlight. When they look complete, don't rush it - let it have another week.

Detailed:
1. Get organised

Choose a space to use as your 'lab' - An ideal room to use will be draft-free, such as a small cupboard. Kitchens and bathrooms are generally not suitable because of the increased risk of mould. Take everything you will need into your lab at this point, you want to keep air currents to an absolute minimum - close the door and keep it closed until you are finished! - to lower the odds of contaminant spores getting into the MycoPots.

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 hand wipe and let them completely air dry first or you'll struggle to put your sterile gloves on!

3. Inoculation

Give the syringe a good rattle and shake to help break any clumping. Remove the cap from the end of the syringe, unwrap the sterile needle and screw it on to the syringe. Thoroughly wipe the rubber injection ports on the MycoPot and allow them to dry before swiftly piercing the needle through and injecting 0.5 - 1ml of liquid, try to get close to where the substrate meets the plastic wall.

When inoculating other MycoPots or grow kits with the same syringe, it's advised to flame sterilise the needle until it glows red hot, giving 15 seconds or a tiny squirt of liquid to allow the needle to cool down before injecting. Or you could purchase some extra needles and switch them over if you prefer.

Never wipe a needle with an alcohol wipe - this will only sanitise it. It's best flame sterilising for proper sterilisation.

4. Colonisation

Now it's time to leave the MycoPots in a safe place to fully colonise with mycelium. We recommend that you place the MycoPots into a plastic zipper bag to keep them as clean as possible for the next stages. Remember not to seal the bag fully to allow the growing mycelium to breathe! It's recommended to leave the MycoPots to colonise in a room with indirect sunlight or light from a flourescent bulb.. although a dark cupboard won't do any harm. Just keep them out of direct sunlight and they will be fine!

Regarding heat, many species 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. Keeping the colonising MycoPots somewhere between 18C and 26C is ideal. 26C will be noticeably faster than 18C but with some patience it will get there regardless.

If you are determined to have a warmer environment for faster colonisation times, we strongly advise against the use of heat mats as they can dry out the bottom of the substrate and stall colonisation. It's a far better idea to store your substrates somewhere with more balanced heat like a warm cupboard above a fridge or near the water boiler..

Generally, you will start to see mycelium growth after 10 days depending on optimum conditions - if not, just hang in there a while longer as you may have injected too deep to see any growth yet.. Injecting gourmet spores or culture close to the walls of the container (pot in this case) is of course going to show quicker results than injecting deeper into the substrate - and that's the most common reason we get emails saying 'I can't see any mycelium..'. Patience is key here!

It normally takes around 4-6 weeks for the MycoPots to fully colonise with white mycelium - but again, this depends on a range of factors such as temperature, genetics, etc.

When the MycoPots have reached full colonisation, it's highly recommended that you leave them for an extra week to allow the mycelium to consolidate within the core of the substrate.

 

STAGE 2: PREPARE HUMIDITY TENT

We will now set up the chamber for growing your mushrooms.

For this stage, you will need:

  • 1 x Bag of perlite to provide humidity (supplied)
  • 1 x Humidity tent for fruiting your mushrooms in (supplied)
Summary:

Place your perlite in a strainer and rinse under the tap until soaking. Shake off some of the excess water and pour into the humidity tent.

Detailed:

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 but make sure you don't remove too much.

2. Pour the damp perlite into your humidity tent - this will create the humid environment mushrooms love.

 

STAGE 3: FRUITING

Now, simply remove the lids from your MycoPots and discard them - you won't need to use the lids again. Mist the vermiculite layer on top of the substrate heavily to make sure it's very damp.

Then, place the open MycoPots directly onto the perlite.

Fold over the top of the humidity tent(s) and either leave as is (if the bag 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 them shut.

 

STAGE 4: HUMIDITY CONTROL

For this stage, you will need:

  • Spray bottle to mist your cakes with water (not supplied)

You will now need to mist your MycoPots with water regularly to ensure constant hydration.

Mist the top vermiculite layers directly until they glisten with moisture and when you can no longer see the glisten on them, it's time to mist them again..

Misting 2-4 times a day is pretty common for ultimate results. But if this is not possible, just try to mist them once a day.

Click here to view some photos which will help you see what is meant by 'glistening with moisture'.

The evaporation of moisture from the cakes is the trigger for mushroom pins to form and grow - this is why the humidity tents we supply in our grow kits 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 poor harvest.

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

An extra tip on humidity: It may be best to pour the perlite from your humidity tent(s) into a strainer and hydrate it again at least once or twice a week.. moisture will evaporate out of the bag quickly.

The more work you put in, the greater your reward will be.

 

STAGE 5: HARVEST TIME

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

When you have harvested all of your mushrooms from your first flush, you can place the MycoPots back within your humidity tents and continue the misting process for more fruting!

If you have looked after your grow kit well, you should achieve a few flushes of mushrooms. But, eventually the mushrooms will use up all of the nutrients within the substrate and no further mushrooms will be able to grow. You cannot re-inoculate and re-use the grow kits multiple times (a question we get asked quite often).

If you follow these instructions carefully, you will have no problem in growing your own beautiful mushrooms..

Good luck and have fun!
