Micronized Soft Rock Phosphate 0-9-0 (Cal-Phos)

High Phosphorus • Strong Roots • Enhanced Bloom Support

Our Micronized Soft Rock Phosphate, also known as Cal-Phos or Colloidal Phosphate, is derived from the fossilized remains of ancient organic life. Mined and processed in Canada, this natural, non-metallic mineral is rich in phosphorus, calcium, and trace minerals essential for strong root systems, vibrant blooms, and long-term soil fertility.

Key Benefits

🌱 Boosts Germination & Root Growth
Provides essential phosphorus and calcium to support early plant development and stronger root systems.

đź’§ Improves Nutrient Movement
Helps translocate vital minerals into plant tissues, promoting healthier, more resilient growth.

⚡ Highly Refined & Water-Soluble
Processed to a fine particle size under 10 microns for faster availability to plants.

đź’¦ Ideal for Foliar & Soil Applications
Can be suspended in water for foliar sprays or applied directly to soil for quicker nutrient uptake.

🌸 Supports Bloom & Fruit Development
Acts as a natural bloom booster, increasing flower and fruit production without harsh chemical inputs.
