DIF is short for Difference. This is a technique that some growers use to control the
growth characteristics of certain plant types. The technique involves dropping the
greenhouse temperature significantly an hour or two before sunrise. After sunrise, the
temperature is raised gradually for an hour or so until the normal day time temperature
target is achieved.
