Start-R is a predominantly organic, incredibly complex bio-stimulant for use with seedlings, vegetatively growing plants and plants in early bloom. It has 2 forms of nitrogen that, when used with our Basis A&B, change the NPK to a higher Nitrogen content suitable for seedlings, vegetative growth, and plants in early bloom. It also contains Humic and Fulvic acids, L-amino acids, and a root enhancing Bio-Stimulant derived from auxin- and cytokinin-rich Irish kelp.Helping to promote a healthy root system in vegetative and early flowering leads to larger yields during harvest, so get your plants off on the right foot with Start-R!START-R is responsible for:Fast and strong development of rootsPromotion of plant growth and vitalityImprovement of media structure and nutrient uptakeRapid recovery from transplant shock .hb-qff .hb-qff-row { display: grid; grid-template-columns: 140px 1fr; gap: 14px; align-items: baseline; margin: 0 0 10px; } .hb-qff .hb-qff-row:last-child { margin-bottom: 0; } .hb-qff dt, .hb-qff dd { margin: 0; } @media (max-width: 480px) { .hb-qff .hb-qff-row { grid-template-columns: 1fr; gap: 3px; } } Quick Feed Facts THE HYDRO BROS Dilution / Dose 1ml per litre, from week 1 of the vegetative phase through week 2 of flowering. When To Use Seedlings, cuttings, and early vegetative growth through to the start of flower — also ideal after transplanting to speed recovery. Substrate Fit Soil, coco, and hydro. Grower Notes Used with Basis A&B, Start-R shifts the feed's NPK toward higher nitrogen for strong early root and vegetative development.
