THE CALCIUM DENSITY
Cannabis needs plenty of calcium to grow thick, heavy buds. Our sea-based aragonite releases minerals slowly to help your plants build strong roots and frosty crystals. It is an easy way to give your crop the structural support it needs for a better harvest. Use our natural calcium to grow healthier plants every time.
Application & Timing
01
Build Mix: Integrate 1-2 cups of aragonite per cubic foot of container soil mix.
02
Activate Biology: Allow the soil to settle and biological activity to establish.
03
Water In: Thoroughly water the soil to initiate slow-release mineral dissolution.
04
Watch It Work: Monitor root development and nutrient uptake over the growing cycle.

Cannabis Cultivation FAQ
Is Aragonite Soil OMRI Certified?
Yes, our aragonite soil amendment is OMRI Certified. This ensures it is safe for organic cultivation and meets the rigorous standards for use in licensed cannabis gardens.
What is the ideal pH range for cannabis?
We recommend a pH range of 6.0 to 6.8 for optimal cannabis growth. Aragonite helps maintain this ideal acidity while providing essential bioavailable calcium.
When should I apply calcium during the flowering stage?
Apply aragonite soil amendment during the early flowering stage. This timing supports trichome density and bud firmness, ensuring your plants have the calcium they need for peak terpene production.
Can I use aragonite in fabric pots?
Absolutely. Aragonite is highly compatible with fabric pots. Its slow-release nature prevents root burn and provides a stable mineral foundation for root architecture and healthy growth.
