Lowering temperature set points in the greenhouse may help you combat rising heating costs.
In recent weeks, several growers have contacted Michigan State University Specialists about leaf discoloration on geraniums, especially the purpling of lower leaves.
In the second part of a two-part series, Michigan State University researchers share their findings in germinating seedlings with LED lights.

Greenhouse crop production often employs the use of plant hormones and growth-regulating chemicals to control growth such as plant height, rooting and flowering. Abscisic acid (ABA) is a natural plant hormone produced in roots in response to drought conditions. ABA is moved to the leaves, where it stimulates the closure of stomata, reduces water loss
Daily light integral (DLI) refers to the cumulative amount of photosynthetic light that is received in one day. Determination of the DLI requires that light is measured repeatedly over time and then integrated. It cannot be determined instantaneously. DLI is expressed as moles of photons of light received per square meter per day (mol∙m¯²∙d¯¹), or
Efficient production of bedding plants requires information on how temperature, photoperiod, and daily light integral (DLI) influence crop timing and flowering characteristics. During the past several years at Michigan State University (MSU), we have performed experiments with seed-propagated annuals to quantify how temperature and DLI influence flowering time and plant quality. In the 12th and
Scheduling annual bedding plants in flower for specific market dates is of increasing importance to greenhouse growers. Plants not in flower when planned or in flower too early can create greenhouse space challenges, delay shipping and reduce plant quality. During the past several years at Michigan State University (MSU), we have performed experiments with seed
Producing spring bedding plants in an energy-efficient manner requires information on how crops respond to average daily temperature and daily light integral (DLI) so bedding plants can be more precisely scheduled. At Michigan State University (MSU), we have performed experiments with numerous seed-propagated annuals to quantify how these environmental factors influence flowering time and plant
