Vermiculite (Medium Grade) | 100g
Vermiculite is a white-yellow-brown, crystalline mineral clay with a bewildering array of uses (mostly in horticulture, insulation and fireproofing). Popular for an incredibly wide range of commercial and other purposes – so much so that there’s even an international trade body dedicated to the cause, The Vermiculite Association – this material is especially useful for the keen gardener or mycologist!
Examples of vermiculite’s horticultural versatility include its use as an inorganic germination and rooting medium/ingredient, “no soil” hydroponic growing medium and fungal substrate. It’s also great for aerating and hydrating any potting soil blend and can also prove useful for the slow-release application of agricultural chemicals. Currently, vermiculite’s largest producers are Brazil, China, Russia, South Africa and the USA.
A word of advice: if you’re mixing up a cactus or succulent mix, we’d always recommend choosing perlite over vermiculite, due to the latter’s propensity to retain more moisture for longer – which in the cactus world is usually a bad thing!
