Humic acid chelates nutrients such as magnesium, calcium and iron, acting as a natural carrier that transports those nutrients and vitamins into the plant more efficiently than they would move on their own.\u003c\/p\u003e\u003cp\u003eBeyond nutrient transport, Royal Black stimulates root development and enzymatic function, increases vitality in seedlings and clones, and helps plants make more efficient use of the nutrients and vitamins already in their feed. It is enriched with a small amount of potassium silicate, which supports stronger cell walls and increased chlorophyll production, meaning growers using Royal Black do not need a separate silicon product.\u003c\/p\u003e\u003cp\u003eRoyal Black is particularly suited to soil and coco. Because coco does not naturally contain the humate matter found in soil, pre-treating coco pots with Royal Black before planting is a common way to give young plants a good start. It works well alongside any branded fertiliser or additive.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOMRI listed for use in organic growing\u003c\/li\u003e\n\u003cli\u003eChelates calcium, magnesium and iron for more efficient uptake\u003c\/li\u003e\n\u003cli\u003eStimulates root growth and enzymatic activity\u003c\/li\u003e\n\u003cli\u003eIncreases vitality in seedlings and clones\u003c\/li\u003e\n\u003cli\u003eBuilt-in potassium silicate supports cell strength and chlorophyll production\u003c\/li\u003e\n\u003cli\u003eIdeal for pre-treating coco or soil before transplanting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Future Harvest","offers":[{"title":"1L","offer_id":53500708618506,"sku":"FH-ROYALBLACK-1L","price":19.9,"currency_code":"GBP","in_stock":true},{"title":"4L","offer_id":53500708651274,"sku":"FH-ROYALBLACK-4L","price":69.9,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53500708684042,"sku":"FH-ROYALBLACK-10L","price":119.5,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53500708716810,"sku":"FH-ROYALBLACK-20L","price":199.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/FHDRoyalBlack.jpg?v=1786377466","url":"https:\/\/hydrocropshop.co.uk\/products\/future-harvest-royal-black","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
