Because it contributes nothing of its own to the solution, whatever you dose is exactly what the roots receive. The open structure encourages roots to spread and branch rather than circle, and the soil-free approach sidesteps the soil-borne diseases that come with organic media while still giving beneficial bacteria and microbes plenty of surface to colonise.

It buffers the pH you just set, releases nutrients you did not add, or holds so much water that the roots never see air. An inert volcanic aggregate does none of that. It holds the plant up, drains freely and keeps out of the way, so the only variable left is the feed you decided to give.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRinse the medium through with clean water before first use.\u003c\/li\u003e\n\u003cli\u003eFill pots or system modules and settle the medium around the root ball.\u003c\/li\u003e\n\u003cli\u003eFeed little and often, since a free-draining aggregate holds less water than coco or soil.\u003c\/li\u003e\n\u003cli\u003eWatch for salt build-up and flush with plain water periodically.\u003c\/li\u003e\n\u003cli\u003eWash, sterilise and reuse between crops.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eVolcanic rock growing medium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003e100% natural, chemically inert\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003epH\u003c\/th\u003e\n\u003ctd\u003eNeutral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuitable For\u003c\/th\u003e\n\u003ctd\u003eHydroponic and aquaponic systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReusable\u003c\/th\u003e\n\u003ctd\u003eYes, over multiple crop cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSizes\u003c\/th\u003e\n\u003ctd\u003e1 litre, 3 litre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Lava-Lite","offers":[{"title":"1 Litre","offer_id":53446971293962,"sku":null,"price":5.49,"currency_code":"GBP","in_stock":true},{"title":"3 Litre","offer_id":53446971326730,"sku":null,"price":9.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/lava-lite-hydro-gro-1-litre-1.jpg?v=1785332908","url":"https:\/\/hydrocropshop.co.uk\/products\/lava-lite-hydro-gro","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
