The Superior Calcium Advantage
Why mineral calcium outperforms synthetic inputs at scale for specialty crop production.
Unlike traditional garden lime, which is a coarse calcite powder, aragonite is a fine, bioavailable mineral form. This crystal structure allows for a slow-release calcium delivery that is essential for root architecture and terpene density. We provide the mineral infrastructure your soil needs to thrive without synthetic inputs.

The Raised Bed Guide
01
Build Your Mix
02
Activate Biology
03
Start with a base of high-quality organic compost or aged manure. We recommend a 1:1 ratio of organic matter to aragonite soil amendment for optimal mineral structure.
Let your soil sit for 2-4 weeks before planting. This allows beneficial microbes to establish and begin breaking down the organic matter into bioavailable nutrients.
Water In
Thoroughly water the soil amendment to ensure it is fully hydrated. This is critical for the slow-release calcium to become bioavailable to your root system.
Identifying Deficiency
Tomatoes
Tip burn and blossom end rot are common indicators of calcium deficiency in our specialty crops.
Peppers
Weak stems and poor cell wall integrity can lead to stunted growth and reduced yield in pepper plants.
Leafy Greens
Tip burn and leaf curling are early warning signs of calcium imbalance in leafy greens and herbs.
Garden Safety
Expert guidance on safe application and handling for organic gardeners and cultivators.
Is Aragonite safe for children and pets?
Aragonite is a natural mineral and is safe for children and pets. It is non-toxic and does not leach harmful chemicals into the soil. We recommend keeping it away from direct contact with skin and eyes, as with any mineral amendment.
How often should I apply Aragonite?
For organic gardens, we recommend a single application per growing season. For cannabis cultivators, we suggest a light application at the start of the vegetative phase and a second application at the beginning of the in-flower stage to ensure optimal calcium levels.
Is Aragonite safe for edible crops?
Yes, Aragonite is safe for edible crops. It is a natural, bioavailable calcium source that supports healthy root development and plant architecture without synthetic additives or chemical residues.
What is the OMRI status?
Aragonite is certified organic by the Organic Materials Review Institute (OMRI). It is a non-synthetic, slow-release amendment that is approved for use in organic farming and home gardens.
How does it compare to lime?
Unlike garden lime, which is a quick-release alkaline source, Aragonite is a slow-release, bioavailable calcium amendment. It provides a more stable pH and better root zone chemistry for long-term soil health.
