Q
How many ml of spores does each pit need between them?
A
If you've got a 3ml gourmet spore syringe, you can safely split the solution equally between both pots until there's no more solution left over.

Mushroom grow kit
MycoPots
Two small sterile pots, one easy method. Inject each pot with your own gourmet culture, colonise, dunk and fruit. The twist is that two separate pots let you grow two different mushrooms side by side from one kit.

The short version
A single-stage gourmet kit built around two small sterile pots. You inject your own culture straight into each pot's rubber port, let the substrate colonise, then dunk the colonised cakes in water and fruit them in the included tent. Because there are two separate pots you can run two different species at once. It colonises faster than a single big box and is forgiving in cooler rooms, which makes it a good first kit. Expect a medium harvest over several flushes.
How it works
How a MycoPots grow works
One stage, no grain transfer step. You inject the substrate inside each pot directly, colonise, then dunk and fruit. Clean hands, a steady warm spot and some patience get you there.
1
Inoculate both pots
Fit a fresh needle, wipe the grey rubber port on each pot, then inject your gourmet culture straight into the substrate. There are two pots, so you can split one species across both or run a different one in each. One 2ml syringe is enough for both pots. Work somewhere clean and draught-free.
2
Colonise the substrate
Keep the pots somewhere steady with the lids on. Aim for around 24 degrees, though anywhere from 18 to 24 is fine, just keep it consistent and watch for condensation. Skip the heat mat. Leave them shut until the substrate is solid white, and do not lift a lid before then. This usually takes 1 to 3 weeks.
3
Dunk the cakes
Once a pot is fully white, tip the solid cake out and submerge it in cold water, weighed down so it stays under. This rehydrates the cake and sets it up to fruit. Leave it anywhere from 6 to 24 hours, longer is better, then rinse it and let the excess drain off.
4
Fruit your mushrooms
Place the dunked cakes in the grow tent and hold the temperature a little cooler, around 20 to 22 degrees. A small slit in the tent plus a low fan in the room gives the fresh air that triggers pinning. With the Enhanced kit the perlite holds the humidity, so you do not mist. With the Regular kit you mist the cakes a few times a day instead. First pins arrive in 3 to 7 days.
5
Harvest and go again
Cut each mushroom just as the veil under the cap starts to tear, before the spores drop and make a mess. After you have picked a flush, dunk that cake again to rehydrate it and put it back in the tent. Dunking between flushes is what gets you more, so keep going until the nutrients are spent.
Why this one
What makes MycoPots different
Most kits give you one block to fill and fruit. MycoPots gives you two small pots instead, and that one change is the whole point of the kit.
Two MycoPotsA single-box kit
Species at onceTwo, one per pot if you wantOne, the whole box is committed
ColonisationFaster, two small cakes run quicklySlower, one larger mass to fill
If one failsYou still have the other potThe whole grow is lost
Cooler roomsForgiving, no incubator neededWants more steady warmth
YieldA medium harvest, several flushesA bigger single block
It also colonises noticeably faster than our single MycoBox, because two small cakes fill quicker than one large one. That speed and the safety of two separate pots are why it has stayed a popular first kit since we launched it in January 2019.
Why it works
How we make it sterile
Sterile is the whole point of the kit, so it is worth knowing what that means here. The substrate inside the pots is the part that has to arrive perfectly clean, and this is how we get it there.
Autoclaved
The filled pots are heat-sealed in autoclave bags and sterilised in distilled water at 121 degrees for 90 minutes.
Cleanroom sealed
They pass through a HEPA-filtered corridor to a cleanroom, where a suited operator handles them in front of a 12 foot laminar flow hood.
Desiccant dried
Everything is rebagged with a desiccant sachet that pulls out residual moisture, starving stray microbes, then heat-sealed shut.
Worth noting
No process is ever perfect, which is exactly why every kit is backed by the Sterile Guarantee further down.
In the box
What's included
Two versions. Both contain the two sterile pots and substrate, but they fruit differently.
Regular MycoPots
Needs a 2ml culture, you mist by hand
- 2 x 280ml HEPA-filtered Inject-thru pots (9cm wide, 6cm tall)
- Sterile substrate inside each pot (organic rye grain, coffee, coir, lime, gypsum)
- 2 small HEPA-filtered grow tents, one per pot
- Hygiene kit: alcohol wipes, 18G 40mm needles, hand wipes, face mask
- Sterile gloves (optional, but advised)
Enhanced MycoPots
Needs a 2ml culture, perlite holds the humidity
- 2 x 280ml HEPA-filtered Inject-thru pots (9cm wide, 6cm tall)
- Sterile substrate inside each pot (organic rye grain, coffee, coir, lime, gypsum)
- 1 XL HEPA-filtered grow tent for both cakes
- 1.5L perlite for hands-off humidity (no misting)
- Hygiene kit: alcohol wipes, 18G 40mm needles, hand wipes, face mask
- Sterile gloves (optional, but advised)
Regular or Enhanced?
The Enhanced kit swaps the two small tents for one larger XL tent and adds rinsed perlite, which holds the humidity for you so there is no misting. The Regular kit is fine if you are happy to mist the cakes a few times a day. Both grow the same mushrooms, the difference is how much the kit does for you.
The one thing you add
What you'll need
The culture is not included.
MycoPots arrives sterile and ready to inoculate, so you supply the living part: a gourmet liquid culture or spore syringe. One 2ml syringe is enough for both pots. We make gourmet liquid cultures you can inoculate it with.
Liquid culture has known, predictable genetics and can be incubated a little warmer, so it tends to colonise faster and more reliably. Spore syringes are cheaper and offer more variety, but are never fully sterile, so incubate them slightly cooler to let the mycelium outrun any stragglers. Because there are two pots, this is a nice kit to put a liquid culture in one and try something else in the other.
Whatever you inoculate with, give the mycelium a clean start: wipe the rubber port, work in still, draught-free air, and flame the needle. Most failed grows trace back to a sloppy injection rather than a bad kit. We stock the sterile gear for it (a still-air box, wipes and gloves) in sterile and lab equipment.
Risk, reversed
The Sterile Guarantee
We guarantee the kit, not the grow.
Every kit is made fresh and arrives sterile and sealed. If a pot shows contamination on arrival, before you have inoculated it, send us photos and we will replace it. What happens after you open it comes down to your technique and conditions, which no reputable seller can promise for you. So we stand fully behind the kit reaching you clean, and the troubleshooting below helps with the rest.

When things look off
Common issues
Because you do the growing, the odd thing can go sideways. Here are the common ones and what they usually mean.
One pot is slow
Normal with two pots, they rarely finish in step. Wait for each to go solid white before dunking it, and judge them separately.
Yellow liquid
Normal. That is metabolites, the mycelium's own waste, not contamination.
Green, grey or sour
That is contamination. Bin the affected pot and keep it away from the other one so it does not spread.
Tent looks dry
On the Regular kit, mist more often. On the Enhanced kit, rehydrate the perlite when you dunk and check the room is not too cold.
The full step-by-step lives in the MycoPots grow guide, and the grow-kit troubleshooting guide goes deeper on contamination and temperature.

Common questions
Frequently asked
Aim for about 24 degrees while the substrate colonises; anywhere from 18 to 24 is fine as long as it is steady, and watch for condensation. This kit is forgiving in cooler rooms, so an incubator is not essential. Drop it a couple of degrees, to around 20 to 22, for fruiting. Avoid heat mats, they cause condensation.
Yes. There are two separate pots, so you can inject a different gourmet culture into each one and grow them side by side. If one pot has a problem you still have the other.
No. You add your own gourmet liquid culture or spore syringe. One 2ml syringe is enough for both pots. We stock gourmet liquid cultures separately.
Any legal gourmet species you have a culture for. It suits oyster mushrooms, Lion's Mane, Shiitake and similar. We sell gourmet liquid cultures you can inoculate it with.
The Enhanced kit comes with one larger XL tent and 1.5L of perlite that holds the humidity for you, so there is no misting. The Regular kit has two small tents and you mist the cakes a few times a day. Both grow the same mushrooms.
Yes. Once a pot is fully colonised you tip the solid cake out and submerge it in water for 6 to 24 hours before fruiting, then again between each flush. The dunk rehydrates the cake and is what gets you more mushrooms.
Roughly 1 to 3 weeks for the substrate to colonise, then a dunk and a few days to pin. So around 4 to 6 weeks from inoculation to the first flush, depending on species and temperature.
Send us photos before opening it and we will replace it, that is our Sterile Guarantee. Contamination that appears after you inoculate comes down to technique and conditions, so check the troubleshooting first.

Questions and answers
Q
Do you need a 3ml gourmet syringe per pot?
A
You only need one 3ml gourmet syringe for the full kit :)
Q
How much substrate is in each pot?
A
Each MycoPot is 280ml in volume. so they are filled to the top with around a centimetre or so of vermiculite for extra contamination resistance.
