Lower grade feeds drift in pH, precipitate out phosphorus and leave a residue behind that eventually locks something out. Working from pharmaceutical-grade inputs means the tank you mixed on Monday is still the tank you think it is on Thursday, which is most of what consistency in hydro really comes down to.\u003c\/p\u003e \u003ch3\u003eHow to Use\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eNever mix Part A and Part B together in concentrate.\u003c\/li\u003e \u003cli\u003eAdd Part A to the water, stir thoroughly, then add Part B and stir again.\u003c\/li\u003e \u003cli\u003eFeed A and B at equal rates and build up to your target EC.\u003c\/li\u003e \u003cli\u003eAdjust pH only after both parts and any additives are in the tank.\u003c\/li\u003e \u003cli\u003eMonitor EC and top up the reservoir as the plants draw it down.\u003c\/li\u003e \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\u003eTwo-part mineral base nutrient\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSizes\u003c\/th\u003e\n\u003ctd\u003e1 litre, 5 litre, 10 litre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystems\u003c\/th\u003e\n\u003ctd\u003eRecirculating and run-to-waste hydroponics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMedia\u003c\/th\u003e\n\u003ctd\u003eClay pebbles, rockwool, coco blends\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStages\u003c\/th\u003e\n\u003ctd\u003eVegetative growth through to full bloom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eNetherlands\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"House \u0026 Garden","offers":[{"title":"1L","offer_id":53446969393418,"sku":null,"price":18.49,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":53446969426186,"sku":null,"price":39.49,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53446969458954,"sku":null,"price":62.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/H_G_Hydro_Grow_A_B_Nutrient_1l_af49240d-cf40-49ee-8025-1cd78693b3b0.png?v=1785315649","url":"https:\/\/hydrocropshop.co.uk\/products\/house-garden-hydro-ab","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
