Roots Organics HP2: Organic Phosphorus for Flowering and Fruit Set
Roots Organics HP2 (0-4-0) provides a clean, concentrated source of phosphorus from biogenic phosphate rock to support the transition into heavy flowering and productive fruit set. The minimally processed liquid formula retains the natural character of the phosphate source, delivering 4% available phosphate (P₂O₅) in a plant-ready form that integrates cleanly into both hydroponic and soil feeding programs without contributing potassium or nitrogen.
Phosphate Rock Phosphorus for Organic Hydroponic and Soil Feeding
HP2's pure 0-4-0 profile makes it a precision tool for growers who want to adjust phosphorus levels independently — adding bloom support without altering the nitrogen or potassium balance set by their base nutrient. This is particularly useful mid-cycle when phosphorus demand peaks and a single-element boost is more appropriate than a full PK supplement. The 1-quart format provides a workable trial quantity before scaling to 1-gallon, 2.5-gallon, or 5-gallon formats.
Key Features
- 4% Available Phosphate (P₂O₅):: A focused phosphorus input derived from biogenic phosphate rock that supports energy transfer, root development, and reproductive growth during flowering.
- Zero Nitrogen, Zero Potassium:: Pure 0-4-0 profile lets growers add phosphorus precisely without shifting their nitrogen or potassium ratios mid-cycle.
- Biogenic Phosphate Rock Source:: Minimally processed natural phosphate rock retains trace mineral character and behaves predictably in both hydroponic reservoirs and soil media.
- Flowering and Fruit Set Support:: Timed phosphorus increases during reproductive development help plants allocate energy to flower structure and fruit formation.
- Liquid Ease of Use:: Ready-to-mix liquid format dissolves completely in water without the pH swing or solubility issues associated with dry phosphate amendments.
