Description
Crazy Hills Prosper Bloom 5 Litre is a professional flowering base nutrient from Crazy Hills’ UK-designed growing range, formulated to support the intense nutritional demands of the generative growth phase with elevated phosphorus and potassium, reduced nitrogen, and a comprehensive micronutrient complement that sustains plant health through to harvest. Prosper Bloom is the flowering companion to Upthrive Grow, completing a two-stage growing system that takes plants from establishment through to productive, high-quality harvest.
Bloom Nutrition Tailored for Peak Performance
When plants transition from vegetative to flowering growth, their nutritional requirements shift fundamentally. Nitrogen demand reduces as stem elongation slows and the plant’s energy redirects toward reproductive development. Phosphorus demand increases significantly — it is central to ATP energy production that powers the intensive metabolic activity of flower and fruit development. Potassium demand rises sharply as plants use it to regulate water movement, activate enzyme systems, and support the accumulation of the complex secondary compounds that determine the quality of the final harvest. Prosper Bloom’s formulation reflects these shifting requirements precisely. The phosphorus and potassium concentrations are elevated to match the bloom-phase demand, while nitrogen is maintained at the level needed to sustain green plant health without suppressing the hormonal flowering signals that nitrate excess can interfere with. At The Horticulture Company, the Crazy Hills range has impressed us as a well-considered new entry to the UK nutrient market, offering professional performance at accessible price points.
When to Switch and How to Use Prosper Bloom
Switch from Upthrive Grow to Prosper Bloom as soon as flowering begins — when pistils first appear or when the plant’s growth pattern shifts to generative. You can overlap the two products for one week during the transition, reducing Grow and increasing Bloom, to avoid any nutritional disruption during this critical phase change. Use Prosper Bloom at the recommended dosage per litre throughout the full flowering period, adjusting dose to plant size and growth intensity. pH-adjust your final solution before feeding.
