Mushroom grow kit

MycDrop

A fast, single-box kit for a first grow. You inject your own gourmet culture straight into the sterile substrate, colonise it (no incubator needed, even in a cooler room), then dunk and fruit in the included tent.

How it works

How a MycDrop grow works

The MycDrop is a single box, no separate grain stage. You inject your gourmet culture straight into the sterile substrate, let it run, then dunk and fruit. Fewer steps than a two-stage kit, and it gets to the finish line quickly.

1

Inoculate the box

Slide the Mini MycoBox out of its bag and wipe the grey rubber port (or ports) on the lid with the green wipe. Fit a fresh needle to your gourmet spore or culture syringe and put 0.5ml into each port. Leave the white air filter strips alone. Work somewhere clean and draught-free.

2.5ml in total, 0.5ml per port (newer kits may have a single port).

2

Colonise the substrate

Keep the box in the cardboard it arrived in, somewhere steady. Aim for around 24 degrees, though anywhere from 18 to 24 is fine, just keep it consistent and watch for condensation. No heat mat. This kit tolerates cooler rooms well and colonises fast, so an incubator is not needed. Leave the lid on until the block is solid white, and do not open it before then.

About 2 to 3 weeks, longer in a cooler room.

3

Dunk the cake

Once it is fully colonised, lift the solid block (the cake) out and submerge it in cold water, weighed down with a plate so it stays under. Cover it and leave it anywhere from 6 to 24 hours. This rehydrates the cake so the humidity for fruiting comes from the substrate itself.

6 to 24 hours, the longer the better.

4

Fruit your mushrooms

Rinse the cake, let it drain, and stand it in the XL grow tent. Drop the temperature slightly, to around 20 to 22 degrees. A small slit each side of the tent plus a low fan in the room gives it the fresh air it needs to pin. Harvest each mushroom just as the veil under the cap begins to tear, then dunk the cake again between flushes for more.

First pins in 3 to 7 days, then 4 to 5 days to mature.

Why this one

What makes a MycDrop different

The MycDrop is built on the same Cylocybe Special substrate as the MycoBox, but tuned for speed and simplicity. It colonises roughly twice as fast as a standard MycoBox, forgives a cooler room, and skips the separate grain stage entirely. The trade-off is size: this is a single small box, so the harvest is medium rather than huge.

SpeedFast, colonises in 2 to 3 weeksSlower, more steps

HarvestMedium, personal use or sharingA full bulk substrate, larger
Best forBeginners who want a quick first growAnyone who wants to learn grain-to-bulk

If you like the single-box idea but want a bigger harvest and do not mind waiting longer, the MycoBox is the larger, slower sibling. If you want the full grain-to-bulk method, step up to the MonoBox.

Why it works

How we make it sterile

The substrate inside the box is the part that has to be perfectly clean before you inoculate it, because once it is sealed it is just waiting for your culture. This is how we get it there.

Autoclaved

The filled box is heat-sealed in an autoclave bag and sterilised in distilled water at 121 degrees for 90 minutes.

Cleanroom sealed

It then passes through a HEPA-filtered corridor to a cleanroom, where a suited operator handles it in front of a 12 foot laminar flow hood.

Desiccant dried

It is rebagged with a desiccant sachet that pulls out any residual moisture, starving stray microbes, and 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

One complete kit in two versions, Regular and Enhanced. Both are ready to inoculate bar the culture, which you add yourself.

MycDrop, Regular

Needs 2.5ml of culture

  • 750ml HEPA-filtered Inject-thru Mini MycoBox (18 x 12 x 5cm)
  • Sterile Cylocybe Special substrate (whole wheat grain, coir, gypsum, lime, vermiculite, coffee)
  • XL HEPA-filtered grow tent (32 x 49cm)
  • Hygiene kit: 2 alcohol wipes, 2 hand wipes, 1 face mask
  • Sterile gloves (optional, but advised)

MycDrop, Enhanced

Needs 2.5ml of culture

  • Everything in the Regular kit
  • 1.5L perlite for extra fruiting humidity
  • So you can skip misting altogether

A SporeKit is not part of this kit. It is a separate product for testing a syringe for contamination before you commit it.

The one thing you add

What you'll need

The culture is not included.

A MycDrop arrives sterile and ready to inoculate, so you supply the living part: a gourmet liquid culture or spore syringe. You need 2.5ml in total, 0.5ml into each lid port. We make gourmet liquid cultures you can inoculate it with.

Liquid culture has known, predictable genetics and 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.

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 one 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.

Slow or nothing

Usually a cool room. This kit copes with lower temperatures but cold still slows it down, so warm it gently towards 24 degrees and give it time.

Yellow liquid

Normal. That is metabolites, the mycelium's own waste, not contamination.

Green, grey or sour

That is contamination. Bin the affected cake and keep it away from your others.

Dry tent, no pins

Too cold for humidity to build, or the fan or light is too close and drying it out. On the Regular kit a light mist helps; the Enhanced kit's perlite usually means you do not need to.

The full step-by-step lives in the MycDrop grow guide, and the grow-kit troubleshooting guide goes deeper on contamination and temperature.
