The University of Florida IFAS (UF/IFAS) Extension and FreshLearn have released a major update to the popular and free BackPocketGrower.org website.
Designers Paul Fisher and Maria Kinslow (UF/IFAS) and Bruce MacKay (FreshLearn) encourage growers to link to this web app for easy access to English/Spanish grower calculator tools, training videos, and fact sheets on a wide range of production topics.
The Tools section includes calculators for fertilizer and agrichemical dilutions, container substrates, light levels, vapor pressure deficit (VPD), crop budgets, and water quality. For example, you can calculate parts per million concentrations of fertilizers or how much daily light integral is contributed by electric lamps. The Training section links to videos and fact sheets on production topics such as handling tissue culture transplants.
