Being unfertilised and un-charged means it won't interfere with whatever feeding routine you're already running, which matters more to a rare-plant collector than most amendments admit. The 1 Litre and 8 Litre sizes are the practical choices for pot-based use; save the 30L and 50L sacks for genuine garden and allotment projects.\u003c\/p\u003e\n\u003cp\u003e💎 SELECT YOUR PERFECT VOLUME PACK:\u003c\/p\u003e\n\u003cp\u003e1 Litre: Ideal for indoor houseplants, delicate succulents, herbs, and terrariums.\u003c\/p\u003e\n\u003cp\u003e8 Litres: Designed for patio container gardening, window boxes, large potted trees\/shrubs, or specialized potting projects.\u003c\/p\u003e\n\u003cp\u003e15 Litres: Tailored for small backyard greenhouses, kitchen herb beds, and raised vegetable planters.\u003c\/p\u003e\n\u003cp\u003e30 Litres: The standard allotment favorite.

Every 1kg of biochar you dig into the earth permanently locks away up to 3.6kg of atmospheric CO2 for centuries.\u003c\/p\u003e\n\u003cp\u003e💡 HOW TO USE FOR MAX RESIDENCY \u0026amp; RESULTS\u003c\/p\u003e\n\u003cp\u003eWe recommend a minimum 10% mix ratio in your chosen planting medium (there is no known maximum—studies show the more you add, the better the results!).\u003c\/p\u003e\n\u003cp\u003eBecause raw biochar acts like a powerful, empty structural sponge, it needs to absorb nutrients and develop microbial root-area relationships (which naturally takes 2–7 months in the ground). For instant powerhouse performance, we highly recommend inoculating (charging\/activating) it first:\u003c\/p\u003e\n\u003cp\u003ePlace your raw biochar into a vessel (like a wheelbarrow).\u003c\/p\u003e\n\u003cp\u003eDilute 'Wood Vinegar' or your favorite liquid fertilizer with water at a 1:100 ratio in a separate container.\u003c\/p\u003e\n\u003cp\u003ePour the mixture over the biochar until it is completely covered, and leave sheltered for 2 days.\u003c\/p\u003e\n\u003cp\u003eDig the activated mix into the top 30cm of your vegetable patch or flower borders in Autumn, Winter, or early Spring to completely restore soil fertility. For potted houseplants, simply mix the raw or lightly-charged biochar directly into your potting soil at time of repotting.\u003c\/p\u003e\n\u003cp\u003e🐾 VERSATILE, MULTI-APPLICATION USE\u003c\/p\u003e\n\u003cp\u003eBeyond premium horticultural composts and raised bed soil amending, this high-purity, toxin-free hardwood carbon is trusted for:\u003c\/p\u003e\n\u003cp\u003eAnimal \u0026amp; Poultry Care: Promotes healthy animal digestion, acts as an internal toxin binder, and eliminates foul ammonia odors in livestock bedding and chicken coops.\u003c\/p\u003e\n\u003cp\u003eAgricultural \u0026amp; Anaerobic Digestion: Supercharges microbial activity in digestion tanks and farming mixes.\u003c\/p\u003e\n\u003cp\u003eWater Filtration \u0026amp; Building Infrastructure: Premium physical structural medium for clean filtering and eco-construction projects.\u003c\/p\u003e\n\u003cp\u003e📊 TECHNICAL SPECIFICATIONS (OXB-BA-DE-30-1-2)\u003c\/p\u003e\n\u003cp\u003eCarbon Content: 84.6% (DMB)\u003c\/p\u003e\n\u003cp\u003eSpecific Surface Area (BET): 300 m²\/g\u003c\/p\u003e\n\u003cp\u003epH-Value: 7.9\u003c\/p\u003e\n\u003cp\u003eMoisture Content: ~25.1%\u003c\/p\u003e\n\u003cp\u003eAsh Content: 3.0%\u003c\/p\u003e\n\u003cp\u003eDry Matter: 74.9%\u003c\/p\u003e\n\u003cp\u003eNutrient Trace Profile: Nitrogen (0.36%), Potassium (0.3%), Calcium (0.5%), Phosphorus (\u0026lt;0.1%), Magnesium (\u0026lt;0.1%)\u003c\/p\u003e","brand":"Black Flag Horticulture","offers":[{"title":"Sample","offer_id":54331712962906,"sku":"BC-ORG-SMPL","price":2.99,"currency_code":"GBP","in_stock":true},{"title":"8 Litres","offer_id":54331712995674,"sku":"BC-ORG-8L","price":13.99,"currency_code":"GBP","in_stock":true},{"title":"15 Litres","offer_id":54331713028442,"sku":"BC-ORG-15L","price":17.95,"currency_code":"GBP","in_stock":true},{"title":"30 Litres","offer_id":54331713061210,"sku":"BC-ORG-30L","price":29.99,"currency_code":"GBP","in_stock":true},{"title":"50 Litres","offer_id":54331713093978,"sku":"BC-ORG-50L","price":49.45,"currency_code":"GBP","in_stock":true},{"title":"1 Litre","offer_id":54331713257818,"sku":"BC-ORG-1L","price":5.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/9861\/4106\/files\/rn-image_picker_lib_temp_2f7810b6-ea0c-48d5-866d-ed1f63301155.png?v=1781820950","url":"https:\/\/blackflaghorticulture.com\/pl\/products\/the-oxford-charcoal-company-pure-biochar","provider":"Black Flag Horticulture","version":"1.0","type":"link"}
