Mushroom cultivation.

A 1 litre bottle of strong 15 percent sodium hypochlorite. You dilute it with cold water on site to clean and disinfect tubs, tools and grow room surfaces between batches.

A 1 litre bottle of 3% hydrogen peroxide (10 volume) for spot-treating early cobweb mould and sanitising tools and work surfaces. It breaks down to water and oxygen and leaves no residue.

Genuine 3M Micropore paper tape, 1.25cm by 9.1m. A breathable, latex-free seal for inoculation points, plate edges and lid holes that lets air and water vapour through while keeping out larger airborne dust and debris.

Clinell sanitising wipes that pair 70% isopropyl alcohol with 2% chlorhexidine, for a fast clean plus lasting cover on ports, lids, tools and gloved hands before you inoculate.

A one litre bottle of 70 percent isopropyl alcohol for wiping down gloves, tools and work surfaces before clean work. It disinfects, it does not sterilise.

A plant-based gelling powder from red seaweed. You add it to a nutrient like malt extract to set firm, clear plates for starting and cleaning up mushroom cultures.

The clean-culture starting point. Grow a spore or culture sample out on sterile agar, see exactly what is in it, then isolate pure white mycelium to take through to grain. This kit does not fruit mushrooms; it makes the clean culture everything after it depends on.

Finely milled calcium carbonate. A gentle, slow pH buffer that holds your casing and bulk mixes steady and adds calcium, without the caustic bite of hydrated lime.

Organic wholegrain brown rice flour, the nutrient half of a classic PF Tek substrate. You mix it with vermiculite and water, sterilise it in jars, then grow from it.

A soluble 15.5-0-0 calcium nitrate: a calcium and nitrogen supplement for compost-grown mushrooms like button and portobello, and for the casing layer that goes on top.

Heat treated, pelletised poultry manure. A slow release nitrogen and mineral feed for the compost you build for button, portobello and other compost loving mushrooms.

A compressed block of coconut-fibre coir. Add boiling water and it breaks down into a clean, water-holding bulk substrate for fruiting mushrooms.

Aged, screened cow manure compost for manure-loving mushrooms. Crumbly and low in odour, it blends with coir or straw and rehydrates to roughly 3 litres from a 1 kg pouch.

A still-air box, a temperature-controlled incubator and a heated fruiting chamber, built into one compact, low-power system. It lets you grow gourmet mushrooms in any season, even through a cold UK winter, without heating the whole house.

A 130 litre still air box with the arm holes already cut for you. It gives you a calm, low airflow space to work with agar, spawn and cultures, so fewer contaminants reach your sterile work.

Food-grade dextrose powder, the simple sugar mushroom mycelium feeds on. You add it to liquid culture and nutrient agar to give cultures a clean, fast carbon source.

Food grade glycerine for the lab. Its main job in mushroom work is as a cryoprotectant, so you can freeze mycelium and spores without ice damage killing them. Supplied in a 130mL bottle.

Powdered calcium sulfate that keeps grain spawn loose and free running, and adds calcium and sulphur without moving the pH.

A simple, all-in-one seasonal kit. You inject the sterile tub with your own gourmet culture, let it colonise, then fruit it in the included tent. Available until 1st November.

Compressed pure hardwood pellets that swell into wet sawdust when you add hot water. The standard base for fruiting blocks, used plain for oysters or blended with soy hull pellets for richer mixes.

Aged, screened horse manure for growing dung-loving and compost-loving mushrooms. You hydrate it, pasteurise it, then spawn it. A base ingredient, not a ready-to-fruit kit.

Calcium hydroxide powder for cold water lime pasteurising straw and other bulk substrates. Stirred into the soak water it raises the pH high enough to knock back competing moulds and bacteria, with no heat needed.

A small set of single-use hygiene items for working clean during inoculation. It covers your hands, your face, your work surface and the injection port, so fewer bacteria and mould spores reach your culture.

Genuine 1 litre Kilner round clip top jars, sold in a box of twelve. The standard glass vessel for grain spawn and small bulk substrate work in a home lab.

Live King Oyster mycelium suspended in a sterile nutrient broth, ready to inject into grain or agar. A faster, cleaner start than spores, from known genetics.

A jar of sterile rye grain fully run through with live King Oyster mycelium, ready to mix into your own bulk substrate. The colonised middle step, done for you.

An all-in-one kit that posts flat through your letterbox, so it never lands with a neighbour. You inject your own gourmet culture, then colonise and fruit in the same bag. No grain stage, no mixing.

A food-grade dry powder made from malted barley. It is the standard sugar base for malt extract agar and malt extract liquid culture, the two media most home growers use to grow and keep clean mycelium.

Live Hericium erinaceus mycelium suspended in sterile nutrient broth, ready to inject into your own sterilised grain to start a colonised batch.

A jar of live lion's mane mycelium grown through sterilised grain, ready to mix into bulk substrate so you can fruit your own Hericium erinaceus at home.

Small, hard millet kernels for making grain spawn. The fine size packs many more growing points into each jar, so colonised spawn breaks up well and spreads fast through bulk substrate.

The compact MonoBox. Same real grain-to-bulk method you inoculate yourself, scaled down to one small grain pot and a tub that fits a windowsill, with a grow tent to fruit in.

The same grain-to-bulk method as the MonoBox, but everything lives in bags. You inject the SpawnBags yourself, mix the colonised grain into sterile coir, and fruit straight from the long MonoBag in the included tent.

Our most popular kit, and the one that teaches the real method. You inoculate the grain yourself, run it through sterile coir, and fruit a proper harvest in the included tent.

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.

Our big, fast all-in-one bag. You inject a single 2L bag of Substrate B with your own gourmet culture and fruit in the same bag. Full colonisation in as little as 10 days.

The original single-stage kit. You inject your own gourmet culture straight into the sterile substrate box through the ports on the lid, colonise, then dunk and fruit in the included tent. One box, no grain step.

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.

A water-soluble protein powder that gives mushroom mycelium ready nitrogen and amino acids. A small amount enriches a litre of liquid culture or agar.

Expanded volcanic glass. Used wet as a humidity buffer in fruiting chambers, and dry as an airy amendment in substrate and casing mixes.

Our original kit, the classic PF-Tek cake brought up to date. You inject one sterile brown-rice cake through a single port, let it colonise, then dunk and fruit it in the included tent. Hands-on, and the friendliest place to start.

The smallest, fastest of our PF-Tek kits. One brown rice flour cake in one box: you inoculate it yourself, colonise it, dunk it, and fruit a medium harvest in the included tent.

The original cake method, the hands-on way. You make up and sterilise eight brown-rice cakes yourself, inoculate them with your own gourmet culture, then dunk, roll and fruit them. You finish it understanding every stage of a grow.

The classic 1990s beginner method, three sterile cakes you inoculate yourself. Inject, colonise, dunk and roll, then fruit all three in the included tent.

Live Pleurotus djamor mycelium suspended in sterile nutrient broth, ready to inject into grain. A fast, warm-loving oyster strain that suits a first grow.

Cleaned whole rye grain for making mushroom spawn. It holds water well, carries the nutrients mycelium needs, and the grains stay separate after sterilising so you can shake the jar to spread growth.

Swann-Morton No.20 surgical blades, gamma sterilised and sealed one per foil pack. A clean, sharp edge for cutting agar wedges and opening culture work in front of a flow hood or still air box.

Grey butyl rubber ports that fit a 12mm hole in any jar lid, so you can inoculate through a needle without opening the jar. The rubber reseals as the needle pulls out.

Live shiitake mycelium suspended in sterile nutrient broth, ready to inject into grain or agar so you can expand your own spawn at home.

A jar of grain fully run through with living shiitake mycelium, ready to mix into hardwood sawdust and grow on. This is the spawn step, not a finished kit.

Caustic soda pellets for degreasing glassware and gear and for nudging the pH of substrate water upward. A strong base that needs care, not a pasteurising shortcut.

Sterile organic rye grain spawn, ready for you to inoculate. Inject your own gourmet culture, let it colonise, then expand it into your own bulk substrate. Sold singly or as a set of three.

A small, low-cost way to test your own spores before you commit them to a full grow kit. Germinate a sample first, see that it runs clean, and only then inject your substrate.

Single-use plastic loops, gamma-sterilised in the bag, for picking up spores from a print, syringe or liquid culture and streaking them onto an agar plate without flaming anything.

A dry sterile rayon swab in a screw-cap tube. Use it to lift spores from a print or gills and smear them onto agar, or to take a sample for a contamination check.

Genuine Unicorn 3T autoclavable bags with a 0.2 micron filter patch. The standard choice for making grain spawn: filled with grain, sterilised in a pressure cooker, then inoculated with your own culture.

A concentrated dry nitrogen supplement for Phase I mushroom compost. Mixed in at the start of composting to raise nitrogen and feed the microbes that heat and condition the substrate.

Expanded mineral flake that soaks up water and lets it go slowly. The standard moisture buffer for PF Tek cakes, bulk coir mixes and casing layers.

Five small borosilicate glass vials with a self-healing rubber port in the lid. You inject and draw through the port with a needle while the screw lid stays sealed, so they suit liquid culture and storing spore or culture samples.

Clean whole wheat grain for making mushroom grain spawn. Medium kernels hydrate evenly and shake apart well, so colonised grain spreads through the jar instead of clumping.

A sealed tub of sterilised wholegrain with a self-healing injection port. Inject your own legal gourmet culture, let it colonise, then break it up and use it to seed a bulk substrate.

A large fabric fruiting chamber that holds high humidity and lets you add fresh air, so colonised blocks and trays pin and fruit in a clean, controlled space.

A roomy polypropylene fruiting tent for gourmet mushrooms. Built-in filter strips let fresh air pass in and out while the enclosed space holds the high humidity your fully colonised substrate needs to pin and fruit.
