But it's also completely \u003cstrong\u003einert\u003c\/strong\u003e. It holds no nutrients of its own, so everything a plant gets has to come from the feed. Coco also tends to grab calcium and magnesium for itself. A general-purpose feed can leave coco-grown plants quietly short of the very minerals they need most. Cocos A+B is Plagron's answer: a concentrated mineral base feed made specifically for buffered coco, covering both growth and flowering from one set of bottles.\u003c\/p\u003e\n\u003ch3\u003eWhy Two Bottles?\u003c\/h3\u003e\n\u003cp\u003eCalcium and phosphorus are both essential, but mix them together at full strength and they bind into a solid the plant can't absorb. So Plagron keep them apart: \u003cstrong\u003ePart A carries the calcium, Part B carries the phosphorus\u003c\/strong\u003e. Added to water separately, they're diluted before they ever meet and stay fully available to the roots.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete base feed for coco, from growth to flowering\u003c\/li\u003e\n\u003cli\u003eDirectly absorbable mineral nutrients\u003c\/li\u003e\n\u003cli\u003eTaken up across a wide pH range, a useful buffer when pH isn't perfect\u003c\/li\u003e\n\u003cli\u003eHighly concentrated: a 1L set makes up to 250 litres of feed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerfect For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHouseplants in coco:\u003c\/strong\u003e Calathea, Pothos, Philodendron and aroids in coco or coco\/perlite mixes, at the low end of the dose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoco-grown veg:\u003c\/strong\u003e tomatoes, chillies, peppers and strawberries in coco bags and pots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowers:\u003c\/strong\u003e hand-watered or drip-fed coco, including Plagron Cocos Premium and our coco mixes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDose:\u003c\/strong\u003e up to \u003cstrong\u003e4ml of Part A per litre\u003c\/strong\u003e, stir, then the \u003cstrong\u003esame amount of Part B\u003c\/strong\u003e.
