It carries the same base nutrition as the brand's one-part powders, split into \u003cstrong\u003ePart A and Part B\u003c\/strong\u003e so each stays chemically stable as a concentrated stock solution rather than a ready-to-use mix.

A concentrated two-part stock solution like DOS is designed to sit in an injector's feed tank and dose automatically as water flows, so every plant receives the same ratio without repeated manual mixing.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixing:\u003c\/strong\u003e Part B mixes at \u003cstrong\u003e240 grams per gallon\u003c\/strong\u003e of stock solution (Part A separately at 360g\/gallon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDilution:\u003c\/strong\u003e at a \u003cstrong\u003e1:100\u003c\/strong\u003e injector ratio, 100lb of concentrate treats roughly 12,000 gallons of feed water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e keep the mixed stock covered and out of direct light; it remains stable for 2+ weeks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStarting pH:\u003c\/strong\u003e mixed stock reads around \u003cstrong\u003epH 5.2\u003c\/strong\u003e in 0 PPM\/EC start water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended feed pH:\u003c\/strong\u003e coco 5.9–6.0, hydro 5.4–5.8, and it performs well in peat-based mixes with water hardness above 0.5 EC\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e two-part powdered stock concentrate (Part B)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK:\u003c\/strong\u003e 0-3-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixing rate:\u003c\/strong\u003e 240g per gallon of stock concentrate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDilution ratio:\u003c\/strong\u003e 1:100 through a proportional injector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable media:\u003c\/strong\u003e hydroponics, coco, peat\/soil with adequate water hardness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Hydroponic Research (Veg+Bloom), made in California\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Veg+Bloom","offers":[{"title":"Default Title","offer_id":53799015809290,"sku":"NUT-VEG3-003-01","price":334.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/veg-bloom-dos-b-1.jpg?v=1790169912","url":"https:\/\/hydrocropshop.co.uk\/products\/veg-bloom-dos-b","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
