The ZK GrowFactor family of zeolite soil amendments represent a leap forward in plant growth enhancement.
What makes ZK GrowFactor better than other zeolites?
Greater surface area
Just 7 grams of ZK GrowFactor has more surface area than a football field! This level of surface area is more than several times greater than that of other zeolites commonly used as soil amendments. Greater surface area gives ZK GrowFactor a significantly greater capacity to retain water, nutrients and micronutrients versus other agricultural use zeolites. This enhanced capacity helps grow media moderate moisture, pH and nutrient availability.

Greater adsorption capabilities
CEC – cation exchange capacity – quantifies the ability of a material to hold and release nutrients and mineral cations that have positive electrical charge. Most all nutrients present in soil that plants can use in their bio-available forms – including nitrogen, phosphorus, potassium, calcium, among others – are present in their cation forms. Soil and other grow media all have some natural cation exchange capacity. Greater water holding capacity is also associated with higher cation exchange capacity in soil. Zeolites are an easy and effective way to boost CEC in soils and natural soil-like grow media.
With more than 5 times the cation exchange capacity of typical zeolites used for soil amendment, ZK GrowFactor zeolites can hold more nutrients and release nutrients to plants faster than other zeolites or soil alone can. This leads to greater nutrient availability and greater buffering against nutrient surpluses, deficits and against swings in grow media pH.

Pre-loaded plant nutrition
Natural zeolites have little to no nutritive value on their own. What a wasted opportunity! Select zeolites in the ZK GrowFactor family come pre-loaded with vital nutrients. This brings immediate enhanced availability of nutrients to plants in grow media.
ZK GrowFactor benefits
- Faster germination and initial growth
- More reliable growth and higher yield vs. fertilizer alone
- Increased resistance to sporadic watering and feeding schedules
- Increased long-lasting soil aeration for superior root health and nutrition
