4-Stage SimPro Line-Up

The SimPro 4-Stage All-In-One System is our most advanced feeding program, engineered to match plant nutrition precisely to each developmental phase. This system separates the crop cycle into four targeted stages, allowing growers to fine-tune structure, flower development, and final quality.

Included Formulas

Vegetation Formula (7-3-11)
Nitrogen- and protein-rich for strong root development, vigorous vegetative growth, and lush green foliage. Fortified with silica and aloe vera to enhance structural strength, stress resistance, and early plant resilience.

Transition Formula (6-2-11)
Specifically designed to reduce stretch during the first phase of flowering. Helps maintain tight internode spacing while directing energy toward flower site development—ideal for growers seeking canopy control and uniform structure.

Bloom Formula (5-6-12)
Phosphorus- and potassium-rich to support flower initiation, enzyme activity, and early trichome formation. Enhanced with seaweed and carbohydrates to improve quality, aroma, and yield.

Boost Formula (4-7-14)
Formulated for mid-to-late flower when silica is removed and nitrogen is further reduced. Elevated phosphorus and potassium, combined with higher levels of seaweed, yucca, and molasses, drive final bulking, terpene development, and cannabinoid expression.

Together, these four formulas provide complete, stage-specific nutrition while maintaining a clean, efficient feeding program suitable for soil, coco, hydroponic, and commercial systems.

• Complete seed-to-harvest nutrition using four stage-specific formulas
  
• Precision feeding for vegetative growth, stretch control, flower set, and final bulking
  
• Organic–mineral hybrid for fast nutrient uptake and strong biological performance
  
• Fortified with molasses, yucca, humates, amino acids, silica, seaweed, and aloe vera
  
• Powered by SimPro Microbes™ — Enhance Life™
  
• Produces enzymes that convert organics into plant-available nutrients
  
• Protects the rhizosphere from pathogens and parasites
  
• Water soluble and compatible with fertigation, hydro, and soil systems
  
• Free from synthetic plant growth regulators (PGRs)
  
• Manufactured in the USA and tested to strict heavy metal standards

Mix Rate:
Mix ½ – 1 tablespoon (5–10 g) per 1 gallon (3.8 L) of water.

General Mixing Guidelines

• Always fill your water container or reservoir before adding nutrients
  
• Mix thoroughly until fully dissolved
  
• Adjust EC and pH after nutrients are added
  

Feeding Tip:
It is more common to overfeed than to underfeed. Allow the top of your growing media to dry slightly between waterings and always water thoroughly with runoff to prevent nutrient accumulation.

Foliar Feeding
EC 0.5 (≈250 ppm US) — Apply weekly before bud set

Clone / Seedling
EC 0.6 (≈300 ppm US) — Use every watering; use Bloom Formula

Coco / Hydro
EC 1.8 (≈900 ppm US) — Use every watering

Soil
EC 1.0 (≈500 ppm US) — Use every other watering

5 g = 1 teaspoon = 5 ml

Runoff Recommendation: Target ~10% runoff to prevent nutrient accumulation. If nutrient issues arise, flush with a mild solution (EC 0.6 / 300 ppm).
