This product has an injection port, so may be injected outside of a SAB as long as you’re very careful. But, to do it correctly and increase your odds of success – always work within a SAB (Still-Air Box).
You will receive either Rye Grain or Wholewheat, depending on stock.
Both grains provide the same high level of results.
- Sterile Organic Rye Grain or Wholewheat with added coffee and gypsum
- 1000ml SpawnTub at 65% fill-level to accomodate G2G and shaking
- Air exchange via HEPA-Filtered lid
- Inject-thru lid (grey rubber port)
- Chlorhexidine 70% IPA wipe for cleaning injection port
How to use
Yes, a lot of our customers skip the SAB whenever they buy kits with injection ported lids – but it’s bad practice and some will suffer contamination as a result.
- Wipe the rubber port and inject 1.5 – 3ml/cc around the SpawnTub™ (against the plastic wall) and finish with a little squirt in the middle
- 26C is the ideal temperature. Mycelium will usually make an appearance after just a few days to a week.
- If you are struggling to maintain a consistant temperature above 20C, your mycelium will grow very slowly or possibly even stall to a complete halt. Consider purchasing our CyLab or building an incubator which can maintain a stable temperature of 26C.
Using Agar Wedge or G2G Transfers
You will absolutely need a SAB to have any success at agar or G2G transfers. But a SAB won’t do anything for you if it’s dirty inside or your technique is rubbish or you’re in a dusty, drafty room. Practice, experience and thinking about how contaminants are transferred around is how to get good at working within a SAB.
We’ve had customers coming and saying to us; “I worked in a SAB but it still contaminated, your product is faulty”. A person could work in the best Cleanroom in the world and still manage to contaminate everything in their path if they aren’t calculating every move they make and thing that they touch. Experiencing contams is what makes people get better at technique.
Our AgarPots come in packs of three because we want to triple the odds of success for customers.

- Remove the lid from your SpawnTub and drop in a piece of colonised agar or pour in some colonised grain you have from another SpawnTub
- Leave in a warm place to colonise at around 20C. Mycelium will usually start growing outwards in a day – it’s fast!
Never try to peel off or inject through the pink filter.

Experience a problem with any product? Don’t panic!
Clean products are what we specialise in, it’s our bread and butter – and we’re good at it. We have to be.
Sterile technique is like driving – you can’t learn it by reading, you need to be practising it always.
While most contamination reports are statistically more likely to be down to beginner error, it’s not always the case.
Sometimes it may actually be us. Does that mean we don’t know what we are doing or that we’re rookies at this?
No. And here’s why.
We regularly purchase live gourmet mother spawn from one of, if not the largest, most accredited mycology business in the world.
This company is BIG and they even run week-long training courses in mycology and have the most incredible set up worth a fortune.
Even they make mistakes. We’ve had to get in touch with them a couple of times after receiving contaminated spawn.
The point we’re trying to make here is that even the masters of mycology mess up. Nature is unpredictable and we all make mistakes.
Although we don’t offer refunds on our products, we will send a voucher for it’s replacement.
Irregardless who is at fault.
A second chance on us 🙂
*If we believe this is being abused by anyone, we reserve the right to remove it at any time.
Although this grow kit can be used without a SAB, it’s good practise and recommended to use one.
We have SAB’s available, but you can always build yourself something – it doesn’t need to be fancy!
…some people even build SAB’s with a cardboard box (inferior but better than open air).
Preparing the syringe
Before using any syringe it’s best to thoroughly distribute the spores or culture within the syringe as best as you can.
A good way to dislodge spores stuck to the plastic syringe wall is to rattle off the corner of something solid whilst spinning the syringe around. Half a dozen times off a table will do the trick. Don’t slam it or you’ll break it.
An even better method is to use a sterile vial; inject into it then fill it back up again and voila – evenly distributed spores.

how long can i keep spawntubs in the incubator once they appear to be fully colonized? in other words, if i felt they needed a bit longer but wont be around to check, will they end up dying in the incubator?

Read more answer nowAsked on 23rd October 2021 12:58 pmA You can get away with leaving them in the incubator for weeks, but if leaving them for extended periods of time you can place colonised SpawnTubs in the fridge. Only species I know this not to work with is Pink Oyster!
Are these filled with your brand new MultiGrain spawn as supplied with MonoBox kits since 27th September? If not, are the Multigrain spawn tubs available to purchase as separate items?
- Should this item be shaken at all at any stage of colonisation to promote a more homogenous mix? If so, could a recommendation be included please?
- Do I need to replace the filter film on the top before and after pressure cooking sterilisation? Or is it to be left?
- What are the exact dimensions of the container. Including the inside lid circumference. And the grain fill level from inside of the pot.
- What weight of grain is in the pot.?

I wouldn’t recommend buying this product if you aren’t planning to use them till so far into the future that they dry out. It takes a verrry long time for grain to dry out.
Dry grain would only be good for the bin :)

Will this need to be mixed with anything once colonisied? Or can i just put in fruiting conditions? Many thanks!

You could just introduce this to fruiting conditions, but this one is really designed as a spawn tub only (to mix with a substrate or more more spawn).
If you are looking to just introduce to fruiting conditions after colonisation then I’d recommend opting for the Rye Grain MycoTub Grow Kit as not only has it got a much higher fill level of grain but it has a vermiculite casing layer too and all the other bits and bobs you’ll want to have (perlite, GrowTent etc)
Is this the same size as the special mycopot that you used to do?
Q Is this the same size as the special mycopot that you used to do? answer nowAsked on 15th February 2021 5:58 pmA These are more than three times bigger than the MycoPots as they were 280ml and these are nearer 900ml.
Are these pots reusable? I.e able to be properly sterliesed etc?
Q Are these pots reusable? I.e able to be properly sterliesed etc? answer nowAsked on 15th February 2021 2:17 pmA Yes, these are made of PP5 (polypropylene) plastic - safe to reuse within a pressure cooker. After a few uses the plastic will become degraded and also the injection ports will become cored from the needle punctures.
