DOS Part A is built to remove that variance: mixed at the manufacturer's stock ratio and fed through an injector, every litre of water leaving the mixer carries the same concentration, run after run, without anyone measuring a reservoir by hand.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStock solution:\u003c\/strong\u003e mix Part A at 360g per US gallon (around 95g per litre) of water to build the concentrate your injector draws from\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInjector dilution:\u003c\/strong\u003e set the mixer to a 1:100 ratio to bring the stock solution down to feed strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion product:\u003c\/strong\u003e use alongside Veg+Bloom DOS Part B (sold separately) for the complete two-part feed — Part A carries the vegetative macro-nutrient load, Part B adds the extra phosphorus and potassium for flowering and fruiting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e at the standard 1:100 dilution, 100lb of Part A treats around 12,000 US gallons of finished feed water, roughly 3,000 gallons from the 25lb size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e soil, coco coir and hydroponic systems fed through a Dosatron or similar proportionate injector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK:\u003c\/strong\u003e 8-0-0 (Part A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e powdered stock concentrate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication method:\u003c\/strong\u003e proportionate mixer \/ fertiliser injector (e.g. Dosatron), not direct reservoir dosing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStock mix ratio:\u003c\/strong\u003e 360g per US gallon (approx. 95g\/L) of water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInjector dilution:\u003c\/strong\u003e 1:100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable media:\u003c\/strong\u003e soil, coco coir, hydroponic systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion product:\u003c\/strong\u003e Veg+Bloom DOS Part B (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Veg+Bloom","offers":[{"title":"25lb","offer_id":53798858129674,"sku":"NUT-VEG3-002-01","price":383.95,"currency_code":"GBP","in_stock":true},{"title":"100lb","offer_id":53798858162442,"sku":"NUT-VEG3-002-02","price":1519.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/veg-bloom-dos-a-stock-concentrate-1.jpg?v=1790169241","url":"https:\/\/hydrocropshop.co.uk\/products\/veg-bloom-dos-a-stock-concentrate","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
