The short answer
A basic home mycology lab needs a way to make or buy sterile agar plates, a clean place to work, and a handful of consumables: petri dishes, a sealing film or tape, scalpel blades, gloves and a surface sanitiser. Add a pressure steriliser if you want to pour your own plates. Everything on that list can be bought inside South Africa, in rand, with domestic delivery, and the South African lab supplies page gathers what local vendors list in one place.
Why sterile technique comes first
Mould spores and bacteria are everywhere: in the air, on skin, on every surface in a kitchen. Agar is a nutrient gel, so anything that lands on it grows. That is exactly what makes it useful. A plate shows you, within days, whether your technique was clean, and lets you cut healthy mycelium away from anything that is not.
The same habits serve a microscopist. Clean slides, clean hands and a still workspace give clearer mounts and fewer stray fungal spores or fibres to confuse an identification. If you also keep gourmet cultures such as oyster or lion's mane for the kitchen, agar is where clean cultures are made and kept. The beginner's guide to agar plates explains the method in full.
The core kit
- Agar. Either agar powder and malt extract powder to mix your own malt extract agar, or pre-poured agar plates if you do not want to sterilise media yourself.
- Petri dishes. Sterile, single use plastic dishes, bought in sleeves so you open only what you need.
- Sealing. Parafilm, or microporous paper tape, to close each plate after you work on it.
- Scalpel. A handle and a supply of No. 11 blades, the pointed shape most hobbyists use for cutting agar wedges.
- Gloves. Nitrile gloves, which you wipe with alcohol before you start.
- Surface sanitiser. 70 percent isopropyl alcohol in a spray bottle, plus a disinfectant scrub such as Bioscrub for benches and tubs.
- Paper towels for wiping down, and a marker for labelling every plate with what it is and the date.
- A pressure steriliser. A domestic pressure cooker that reaches 15 psi, or a purpose made autoclave, if you plan to pour your own plates.
For microscopy you will also want a light microscope, glass slides and cover slips. Those are general lab items rather than mycology stock, so look to a scientific or educational supplier.
Pre-poured plates or pour your own
Pre-poured plates are the easiest start. They arrive sterile and ready to use, so you can practise transfers on day one. The trade off is that plates are perishable and bulky, and they dislike a hot courier van, which is one reason to buy them from a domestic vendor rather than import them.
Pouring your own is cheaper per plate once you own a steriliser. Agar media are normally sterilised at around 121 C, which is what a pressure cooker reaches at 15 psi. You mix the agar and malt in water, sterilise it in a bottle or jar, let it cool until you can hold the container, and pour into dishes inside your clean workspace. Expect a few contaminated plates while you learn; that is the plate doing its job.
A still air box
The single most useful thing you can build is a still air box: a large clear plastic storage tub turned on its side or upside down, with two holes cut in the front for your arms. Wiped down inside with alcohol, it stops air currents carrying dust and spores across your plates while you work. It costs very little, takes an afternoon to make, and is the standard first step for home agar work before anyone considers a flow hood.
Good working habits
- Wipe the box, your gloves, the outside of every container and the scalpel handle with alcohol before you start.
- Work slowly and keep your hands and arms out of the path between the air and an open plate.
- Open a plate only as far and as long as you need to.
- Sterilise the scalpel blade between plates, with a flame or a fresh alcohol wipe.
- Seal and label every plate immediately, then keep plates lid side down at room temperature, out of direct sun.
Sourcing it in South Africa
Buying lab supplies locally makes sense for practical reasons. Agar powder, dishes and sealing film are cheap but bulky, so international shipping can cost more than the goods. Imported lab plastics can attract customs charges. And anything perishable, plates above all, is far safer on a short domestic courier trip than sitting in a customs shed.
CB Shroomy, a vendor based in South Africa, lists most of the core kit: agar powder, malt extract powder, pre-poured agar plates, sterile petri dishes, parafilm, No. 11 scalpel blades, microporous tape, nitrile gloves, Bioscrub, paper towels and an 18 litre autoclave, with Pudo locker or door delivery and card payment in rand through PayFast. For jar work with gourmet species the store also lists injection ports, filter stickers, modified lids and magnetic stir bars, and sterilised grain bags for gourmet spawn. Larger items, such as an incubation cabinet, may be listed as collection only, so read each listing before you order. Browse the wider agar plates and equipment categories to compare other vendors.
Where microscopy fits
Many hobbyists build this kit because they study spores. A sterile workspace helps when you make slides from a print or a swab, and a good habit is to keep a reference set: mount a classic Psilocybe cubensis line such as Golden Teacher beside a species with South African roots such as Psilocybe natalensis, prepared the same way, and compare spore shape, colour and size. The South Africa page lists the vendors who ship spores to you, and the guide to buying spores in South Africa covers delivery and payment.
A note on scope and the law
This guide covers lab practice, microscopy and gourmet species. It does not cover cultivating Psilocybe or Panaeolus. Psilocybe and Panaeolus spores on Culture Cave are sold for microscopy and taxonomy use only, and buyers must know their local law. Buyers elsewhere in Africa can see which vendors ship to them on the Africa page.
