When & How to Use TerraGrow

TerraGrow is packed with a nutrient-rich growth boost package to quickly germinate spores and promote rapid population growth. Consisting of naturally occurring microbial strains that have not been genetically altered, these strains occupy slightly different niches to reduce competition with each other.

TerraGrow easily mixes into a solution and can be applied as a spray, media drench, or through injection system.
