It is formulated to target leaf and stem development during the vegetative phase, giving plants the nitrogen-led feed they need to build a strong structural framework before the switch to flower.\u003c\/p\u003e\u003cp\u003eThe formula is automatically pH buffered and completely sediment-free, so there is no precipitation of nutrient salts out of solution and no risk of blocked drippers in recirculating or drip systems. It carries an extremely low salt index, which keeps it forgiving for novice growers while still giving experienced growers precise control by adjusting the ratio between the three Holland Secret bottles at each stage of the plant's life.\u003c\/p\u003e\u003cp\u003eHolland Secret Grow is designed to be used in conjunction with Holland Secret Micro throughout the vegetative stage, with Holland Secret Bloom introduced as the plant transitions into flowering. It suits soil, coco and hydroponic growing, and is compatible with the rest of the Future Harvest additive range, including Ton O Bud, Carbo Blast and Prop-O-Gator.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAutomatically buffers pH for stable, predictable feeding\u003c\/li\u003e\n\u003cli\u003e100% sediment-free formula, reducing the risk of blocked drippers\u003c\/li\u003e\n\u003cli\u003eExtremely low salt index, using only refined raw materials\u003c\/li\u003e\n\u003cli\u003eWorks across soil, coco and hydroponic systems\u003c\/li\u003e\n\u003cli\u003eRatio can be adjusted against Micro and Bloom to fine-tune nutrition through the life cycle\u003c\/li\u003e\n\u003cli\u003eCompatible with the full range of Future Harvest additives\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Future Harvest","offers":[{"title":"500ml","offer_id":53500706717962,"sku":"FH-HSGROW-500ML","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"1L","offer_id":53500706750730,"sku":"FH-HSGROW-1L","price":14.9,"currency_code":"GBP","in_stock":true},{"title":"4L","offer_id":53500706783498,"sku":"FH-HSGROW-4L","price":39.9,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53500706816266,"sku":"FH-HSGROW-10L","price":79.9,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53500706849034,"sku":"FH-HSGROW-20L","price":124.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/HS_Grow_500ML_webP.webp?v=1786929834","url":"https:\/\/hydrocropshop.co.uk\/products\/future-harvest-holland-secret-grow","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
