It's horticultural biochar. We call it Black Perlite because that's the job most growers will give it — the bit of the mix that keeps soil open, airy and alive — and because \"porous carbonised plant matter\" has never once sold anything to anyone.\u003c\/p\u003e\n\u003cp\u003eBut the difference matters, and it's the whole point. Perlite is a hotel room: clean, empty, and entirely indifferent to who checks in. Biochar is a house. Every granule is riddled with microscopic pores that hold water, grip onto nutrients, and give beneficial soil microbes somewhere to live. A single gram of good biochar can have an internal surface area that would embarrass a tennis court.\u003c\/p\u003e\n\u003cp\u003eThere is, however, a catch that most biochar sellers are rather quiet about. Raw biochar is hungry. Put it straight into your mix and it will spend its first few weeks soaking up nitrogen from the soil around it — nitrogen your plants were expecting to eat. Fresh char also tends to be alkaline, dusty, and oddly water-repellent when dry. None of this is fatal. It just means biochar is at its best when someone has done the tedious preparation first. So we did.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003e🌱 Three Versions, One Honest Principle\u003c\/b\u003e\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eVersion\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003eWhat We Charge It With\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003eBest For\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eVeg Charged\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eBioBizz Bio-Grow, BioBizz Fish-Mix, BioBizz Worm-Humus tea, BioBizz CalMag, BioBizz Alg-A-Mic and BioBizz Acti-Vera\u003c\/td\u003e\n\u003ctd\u003eSeedlings, cuttings, leafy growth, houseplants and the vegetative stage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eBloom Charged\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eBioBizz Bio-Bloom, BioBizz Top-Max, BioBizz Worm-Humus tea and BioBizz Acti-Vera\u003c\/td\u003e\n\u003ctd\u003eFlowering, fruiting and heavy-feeding plants such as tomatoes and chillies\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eRinsed \u0026amp; Buffered (Uncharged)\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eNothing — rinsed of dust and ash, pH and EC checked, then left as a blank canvas\u003c\/td\u003e\n\u003ctd\u003eGrowers who want to charge it themselves with their own feeds or compost teas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cb\u003eWhy These Ingredients\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eNutrients that biochar can actually hold:\u003c\/b\u003e Biochar grips positively charged nutrients — potassium, calcium, magnesium and ammonium — far better than others.

Wait two weeks and you have biochar that's been colonised — which is the whole point.
