Horticultural Research Institute helps you tHRIve with a new web-based series featuring key research findings. The tHRIve series covers research that is directly funded by HRI as well as research that is federally funded.

In announcing the new tHRIVe web series, HRI President Gary Knosher said, “HRI was created to improve the horticultural community through research that addresses critical issues and new innovations. HRI trustees recognize that research is critical to help our industry succeed and grow, and sharing new findings is part of that equation. I’m excited to be part of this focus of using videos not only to share new research but also to engage our community in another way.”

HRI supports research and outreach efforts that prepare the horticultural industry for challenges and opportunities for business success. Connecting the industry to the research is a key component in that endeavor. Starting June 1st, new tHRIve sessions will be posted throughout the year, with all content available online for free at any time at The tHRIve sessions will offer everything from bite-sized research clips to researcher interviews to short webinars to live Q&A with researchers.

The Horticultural Research Institute’s mission is to direct, fund, promote, and communicate horticultural research. The creation and launch of the tHRIve web series is another example of how HRI works to connect the industry to research-backed innovation.

Resilient Plant Research from FNRI

This set of videos focuses on research supported through the Floriculture and Nursery Research Initiative (FNRI) program administered by USDA ARS, the research agency for USDA. FNRI is a noncompetitive, national grants program that greatly benefits environmental horticulture. FNRI plays a critical role in generating scientific research on high priority issues that affect all segments of the floriculture and nursery industry, including postharvest technology, water quality, and pest management.

The set focuses on the FNRI “Resilient Plant Group”, including Dr. John Erwin, University of Maryland, Dr. Jim Faust, Clemson University, Dr. Paul Fisher and Dr. Celina Gomez, University of Florida, Dr. Charlie Hall, Texas A&M, Dr. Roberto Lopez, Michigan State University, and Dr. Erik Runkle, Michigan State University. This group collaborates to benefit greenhouse production through practical, applied research in areas such as energy inputs, water use optimization, resource efficiencies, economic efficiencies, and lighting.


Jim Faust

Dr. Jim Faust, Clemson University, specializes on daily light integral maps and measurements to better predict plant growth and development, how to improve consumer performance of bedding plants, and heat delay of poinsettia.


Charlie Hall

Dr. Charlie Hall, Texas A&M, presents an economist’s view on how a carbon/water footprint drives the economics of production facilities, the rising costs of grower inputs, and key grower-level benchmarks that demarcate operational/financial performance over the past several years


Erik Runkle & Roberto Lopez

Dr.’s Roberto Lopez and Erik Runkle, Michigan State University, share research on rates of rooting hormones, impacts of substrate-applied micro-drenches of plant growth regulators, enhancing foliage color of ornamentals through lighting variables, and lighting applications in horticulture, including photoperiodic, supplemental, and sole-source (indoor) manipulations.


Paul Fisher

Dr. Paul Fisher, University of Florida, discusses research projects spanning labor and automation of transplanting (sticking cuttings), indoor propagation of cuttings, and guaranteeing success for home gardeners. This work was also conducted in part by Dr. Celina Gomez, also at University of Florida.


John Erwin

Dr. John Erwin, University of Maryland, reports on research on plant roots, greenhouse edibles, and reducing labor costs and pesticide applications. It’s all about improving plant growth, resilience, and yield!


HRI tHRIve Session: FNRI's Resilient Plant Researchers
