Ingredients

CVG (coco coir, vermiculite, gypsum), manure & worm castings

Key Features

  • Maintains a balance of air spaces and water retention making it suitable for more tropical species.
  • Pasteurised to kill competing microorganisms and bacteria.
  • Hydrated to field capacity to minimise contamination-risk whilst maximising flushes.

What's in the Box

  • A bag of Mangrove Monsoon (depending on your selected size)
  • 2 x Sterile Wipes
  • Online step-by-step instructions

Overview

Mangrove Monsoon is formulated for high-humidity environments and species that demand elevated moisture levels. Its rich, hydrated texture supports species that thrive in warm, tropical-like conditions. With a slightly wetter composition than standard mixes, it delivers both consistent hydration and a nutrient profile that supports fast, even colonisation.

Recommended for cultivators working with species that prefer high-humidity and a moist habitat. This substrate is aimed at those wanting to further their knowledge with more unusual species of mushroom that thrive in these environments.

  • Increased hydration ideal for tropical and high-humidity species
  • Balanced nutrient profile to support vigorous colonisation
  • Contains worm castings and manure for sustained nutrition
  • Suitable for high humidity strains growing in moist, usually tropical, environments

Our Expert's Opinion

Tony, our resident mycologist, has this to say.

Pros

  • Good for Thirsty Strains - High-hydration mix ideal for those moisture-loving varieties.
  • Strong Flushes - Enriched with manure and worm castings to support vigorous initial flushes.
  • Reduced Contamination Risk - Good aeration despite the higher moisture content helping to reduce contam risk.

Cons

  • Increased Contamination Risk - A higher moisture substrate will require more Fresh Air Exchange (FAE), carrying a greater chance of contamination.

Tips

  • Establish Good FAE - For best results, ensure that you have good fresh air exchange. You'll have more chance of achieving a pantastic outcome!

FAQs

Does this substrate need to be sterilised or pasteurised before use?

This substrate has already been pasteurised — so no — you're good to go!

Do I need to add any water?

No — this substrate is already hydrated to field capacity and is ready to use.

Does it come with instructions?

Yes — you'll receive full step-by-step instructions so that you know exactly what do and when.

Introducing Bulk Substrate

Once your grain is fully colonised (and only then!), it’s time to put your bulk substrate to work. Simply break up the colonised grain and mix it thoroughly through the substrate, making sure it is distributed evenly throughout.

We suggest a ratio of 2:1 (for beginners) or 3:1 — bulk substrate to spawn. Once mixed, leave it to colonise the substrate and let nature do what it does best.

And yes, you could technically use the substrate for something else. Fill a planter. Improve your compost. Make a very elaborate mud pie.

But frankly, it was made for mushrooms. So probs best to give it to the mycelium.

Best for Storage

  • For best results use immediately
  • If not using right away — store somewhere cool and dark, ideally 13–21°C, standing upright without heavy items stacked on top.
  • Keep in original sealed bag to protect the internal microflora balance.
  • Do NOT freeze
  • Best used within 7 to 14 days — before dormant spores or bacteria wake up.

Payment

We currently only accept bank transfer — full details are provided upon checkout.

Why don't we accept card payments? Unfortunately despite progress, the industry is still heavily stigmatised (from banks) which means that even payment gateways such as PayPal don't provide a service for any spore provider based in the UK (also the reason that you cannot buy these spores on the high street).

Is this your first order? We encourage you to read our customer reviews to see the experiences others have had with us.

What happens after I pay? Once we have received payment, a confirmation will be emailed to you. Please allow a few hours for this (within office hours). Meanwhile we'll start preparing your order.
