Cannabis Crop Steering Techniques with Jose Leme, PhD

July 23, 2025

Dr. Jose Lime is a Professor at Southern Illinois University and the principal investigator in the Cannabis Biology and Cultivation Systems lab. He and his team focus on determining how to leverage environmental controls (light intensity, duration, quality, temperature, and CO2), plant nutrition, biostimulants, and hormones to improve plant production. Moreover, the research group is developing techniques to optimize plant yields and quality based on key crop steering traits that increase sustainability and efficiency via plant physiological, biochemical, and agricultural approaches.

During our conversation, we discussed several recent studies that Jose and his team have published, including:

  • Using mechanical stimulation and high stress training to increase production of secondary metabolites
  • Applying plant hormones to increase trichome density
  • Assessing how drought stress affects plant yield and potency
  • Standardizing cloning methods for plant propagation
  • Developing standards for measuring trichome density
