Who's it for?

Anyone who wants mushrooms fast without faff. Total newbie or you've been growing for years, it doesn't matter - inject it, leave it somewhere warm and it gets on with it. From gourmet spores it can be fully colonised in as little as 10 days thanks to Substrate B, which makes it probably the fastest grow kit money can buy right now.

Substrate B

It looks a bit like our Cylocybe Special substrate, but it's a different beast. Substrate B is our Substrate A (the one in the XL Letterbox Monster) with grain added, and it's the fastest substrate we make. We made it for the MycMonster™ and it's where the speed and the big flushes come from.

Inoculation

If you know how to peel a sticker, you know how to inject the MycMonster. It's really that simple. The Peel 'n' Inject sticker is already on the bag: peel it back, inject, press it back down.

Fruiting

You inject it and fruit it in the same MycMonster™ bag, so there's nothing to move or mix. Want more surface area and bigger flushes? Fruit it on its side in the XXL Grow Tent we put in the box.

  • 2L MycMonster™ prefilled with Sterile Substrate B, with a Peel 'n' Inject sticker already on the bag
  • Fruiting: In same bag, or horizontally in the included XXL Grow Tent for more surface area and bigger flush potential, with filter material for the tent's top-FAE gap
  • Hygiene Kit: face mask, 2 x hand wipes, 1 x 70% IPA / 2% Chlorhexidine wipe and 1 x spare 18G sterile needle, plus sterile gloves (tell us your size at checkout)

Before you start

Don't remove the HEPA filters on the bag - they let it breathe without letting anything nasty in.

NEVER cut open the MycMonster™ before it's fully colonised with mycelium, or contamination could ruin the kit.

Not included

  • A gourmet spore or liquid culture syringe - you'll need exactly 12ml (no more, no less), unless you're using a very densely spore-filled smaller gourmet syringe.

Storage

Inoculate your MycMonster™ within 4 weeks of it arriving for the best results.

Temperature

  • Keep it around 23C (give or take a couple of degrees) while it colonises.
  • Never go above 26C!
  • Don't put it on direct heat like a heat mat. They don't work for this hobby.

Shipping and legal
