Extension

Research-based information for greenhouse floriculture focused on production, propagation, and shipping of plugs and cuttings

pH-management for soilless media

Production-monitoring and financial analysis software

Case studies for horticulture training

University of Florida programs including Floriculture Field Days

Research

Applied research for the commercial greenhouse industry, including the Young Plant Research Center, which is an industry-driven research program for the production, propagation, and shipping of young plant material.

Media-pH and micronutrient management, including understanding how factors drive pH changes over time and correction of pH-related problems.

Computer decision-support systems for growers, to help to optimize growing conditions, and to consistently and profitably achieve high-quality crops in time for target sales periods. These tools allow graphical tracking of plant height, flower development, nutrient, or pest levels over time.
