That process preserves the natural hormones, cytokinins, amino acids, polysaccharides and enzymes that make kelp worth using in the first place. It supplies macronutrients including \u003cstrong\u003eN, P, K, calcium, magnesium and sulphur\u003c\/strong\u003e alongside micronutrients such as \u003cstrong\u003emanganese, copper, iron and zinc\u003c\/strong\u003e. Used at \u003cstrong\u003e1ml per litre\u003c\/strong\u003e in soil and coco, it stimulates fine root hair formation and supports a plant's own defences. Available in \u003cstrong\u003e250ml and 1 litre\u003c\/strong\u003e.\u003c\/p\u003e \u003ch3\u003eKey Benefits\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCold water extraction\u003c\/strong\u003e - keeps the active biology intact rather than cooking the value out of the kelp.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDrives fine root hairs\u003c\/strong\u003e - more absorptive surface means better uptake of trace elements.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNatural hormones and amino acids\u003c\/strong\u003e - cytokinins and proteins that support steady, even development.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBroad nutrient spread\u003c\/strong\u003e - macro and micronutrients in one supplement alongside your base feed.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eImproved stress tolerance\u003c\/strong\u003e - stronger plants cope better with heat, transplanting and pest pressure.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eUsable in every stage\u003c\/strong\u003e - from early veg through to late flower in soil or coco.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhy Roots Stall Before the Canopy Shows It\u003c\/h3\u003e \u003cp\u003eEverything visible above the medium depends on root surface area you cannot see. When fine root hairs are sparse, uptake of the trace elements slows first, and the symptoms surface weeks later as dull leaf colour or a flowering stage that never quite lifts. Feeding the root zone a biologically active kelp extract keeps that hidden half of the plant expanding, and the canopy follows it.\u003c\/p\u003e \u003ch3\u003eHow to Use\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eDose at 1ml for every litre of made-up solution.\u003c\/li\u003e \u003cli\u003eWhere you work to EC, put Algen Extract and your other additives into the water first.\u003c\/li\u003e \u003cli\u003eBring the solution up to your target EC with base nutrients afterwards.\u003c\/li\u003e \u003cli\u003eAdjust pH last, once everything is in the tank.\u003c\/li\u003e \u003cli\u003eUse through soil and coco grows at every feed or as a regular tonic.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSource\u003c\/th\u003e\n\u003ctd\u003eNorwegian sea kelp, Ascophyllum nodosum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExtraction\u003c\/th\u003e\n\u003ctd\u003eCold water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDose\u003c\/th\u003e\n\u003ctd\u003e1ml per litre of nutrient solution\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eContains\u003c\/th\u003e\n\u003ctd\u003eN, P, K, Ca, Mg, S plus Mn, Cu, Fe, Zn, amino acids, cytokinins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSizes\u003c\/th\u003e\n\u003ctd\u003e250ml, 1 litre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMedia\u003c\/th\u003e\n\u003ctd\u003eSoil and coco\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"House \u0026 Garden","offers":[{"title":"250ml","offer_id":53446969327882,"sku":null,"price":19.49,"currency_code":"GBP","in_stock":true},{"title":"1L","offer_id":53446969360650,"sku":null,"price":64.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/nutrients-house-garden-algen-extract-1166817482.png?v=1785315647","url":"https:\/\/hydrocropshop.co.uk\/products\/house-garden-algen-extract","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
