on the influence of temperature on stevia growth and development in controlled environments is lacking. Increasing daily light integral generally decreased plant height and individual leaf area ( Evans et al., 2015 ). For field-grown plants
temperatures required to manufacture rockwool render it biologically inert and, therefore, free from potential weeds, pests, and diseases that might normally hinder germination. This manufacturing process also renders a very consistent substrate that possesses
