Where Grow and Bloom carry the changing nitrogen-phosphorus-potassium ratios needed at different life stages, Micro supplies the calcium and micronutrients the plant needs consistently, and is dosed alongside both throughout the entire cycle from rooted cutting to harvest.\u003c\/p\u003e\u003cp\u003eThe formula is automatically pH buffered and completely sediment-free, meaning there is no precipitation of nutrient salts out of solution and no build-up in reservoirs or drip lines. It has an extremely low salt index and is designed to give precise control over feeding: growers change the ratio between the three Holland Secret bottles as the plant moves from vegetative growth into flowering.\u003c\/p\u003e\u003cp\u003eHolland Secret Micro is never used as a stand-alone nutrient — it is designed to be fed together with Grow and, later, Bloom, and works across soil, coco and hydroponic growing methods. It is also compatible with the wider Future Harvest additive range.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSupplies calcium and essential trace elements throughout the whole grow\u003c\/li\u003e\n\u003cli\u003eAutomatically buffers pH for consistent feeding\u003c\/li\u003e\n\u003cli\u003e100% sediment-free, reducing the risk of blocked drippers\u003c\/li\u003e\n\u003cli\u003eExtremely low salt index for a forgiving, precise feed\u003c\/li\u003e\n\u003cli\u003eUsed in conjunction with Grow and Bloom, never as a stand-alone nutrient\u003c\/li\u003e\n\u003cli\u003eSuitable for soil, coco and hydroponic systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Future Harvest","offers":[{"title":"500ml","offer_id":53500706881802,"sku":"FH-HSMICRO-500ML","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"1L","offer_id":53500706914570,"sku":"FH-HSMICRO-1L","price":14.9,"currency_code":"GBP","in_stock":true},{"title":"4L","offer_id":53500706947338,"sku":"FH-HSMICRO-4L","price":39.9,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53500706980106,"sku":"FH-HSMICRO-10L","price":79.9,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53500707012874,"sku":"FH-HSMICRO-20L","price":124.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/HS_Micro_500ML_webP.webp?v=1786929834","url":"https:\/\/hydrocropshop.co.uk\/products\/future-harvest-holland-secret-micro","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
