Why Choose Our 4-Part System?

🎯 Complete Nutrition

All macro and micronutrients your plants need from seed to harvest in perfect balance.

💰 50-70% Cost Savings

Powder nutrients cost less than liquids—you're paying for nutrients, not water and shipping.

🔬 Precision Control

Adjust each component independently for different crops and growth stages.

HOW THE 4-PART SYSTEM WORKS

Our system is designed to give you complete control over your plant nutrition throughout the entire growth cycle:

The Four Components Work Together:

  • Cal-Mag Plus: Provides essential calcium and magnesium throughout all stages. Always added FIRST to prevent lockout.
  • Micro Green: Supplies all 7 essential trace elements. Used consistently throughout the entire grow.
  • Grow Green: High-nitrogen formula for vegetative growth. Gradually reduced during flowering.
  • Blossom Green: High-phosphorus formula for flowering. Increased as Grow Green decreases.

Growth Stage Progression:

Vegetative Stage: Higher Grow Green + moderate others = lush green growth
Transition: Equal amounts of all four = smooth transition to flowering
Flowering Stage: Higher Blossom Green + reduced/no Grow Green = maximum flower production

10 days after order and no show

10 days after order and no show.I called in a few days ago and was told that the order was going to be shipped after having asked about it and waited a few more days and saw that the tracking had no progress still

Will buy again

Great products and they save money because they are dry and you mix them saving on shipping weight alone.
Chemicals produce well when less is more thus stretching their use and adding value.
