Description
High-Purity Phosphorus Support for Root Development and Flower Production
RAW Phosphorus is a highly concentrated nutrient supplement delivering 61% water-soluble phosphate (P₂O₅) along with a small amount of ammonium nitrogen (~9%) to support strong root establishment and energy-demanding stages of plant growth.
Phosphorus is widely known as the “energy element” of plant nutrition. It plays a critical role in root development, energy transfer within the plant, and reproductive growth such as flowering and fruiting. RAW Phosphorus provides one of the cleanest and most concentrated sources available for growers looking to fine-tune phosphorus levels within their nutrient programs.
This fully water-soluble formula integrates easily into soil, hydroponic, and foliar feeding programs, making it ideal for correcting deficiencies, boosting phosphorus during bloom, or customizing nutrient recipes.
Key Benefits:
Root Establishment
Supports strong root development during the early weeks after planting or transplanting.
Energy for Growth
Helps fuel ATP (adenosine triphosphate) production—the energy source used in plant metabolic processes.
Bloom & Fruit Support
Provides essential phosphorus needed during flower initiation and fruit development when energy demand is highest.
Balanced Nutrient Profile
Includes a small amount of ammonium nitrogen that complements phosphorus uptake without adding excess nitrates.
Flexible Application
100% water soluble and compatible with soil, hydroponic, and foliar feeding programs.

RAW Phosphorus can be used as a targeted supplement to increase phosphorus availability, support early root development, and help plants meet the high energy demands of flowering and fruiting stages.
