Zeolite is a mineral that looks like light gray gravel when dug up from the ground. It has a wide range of application, including as an additive to soil for cannabis plants.
The purpose of the trial was to investigate the effect of the company’s Z1 Zeolite on the growth and qualities of greenhouse-grown, low-THC cannabis, irrigation water use and nutrient release and retention.
The trial included two popular growing media used in the cannabis industry. For each growing medium, seven pots with 5%, 10% and 15% of Z1 Zeolite were compared with seven pots containing no Z1 zeolite.
The first substrate was an organic growing medium specifically tailored for growing cannabis. The second was a widely used, high porosity, low density, peat-based growing medium that is widely available for retail purchase in Canada.
"I am very satisfied that the study confirmed our hypothesis that our Z1 Zeolite has merit when used with a widely available Canadian grow medium,” CEO Stephen Harpur said in a statement.
Based on calculated harvest index, flower bud yield was increased where Z1 Zeolite was added.
Shares of Progressive Planet climbed C$0.01 to C$0.06 in Monday’s Canadian trading.
