Growing healthy-looking and high-yielding greenhouse crops, especially on a large commercial scale, is not easy. Having individuals trained in horticulture at different levels is very important, both at the management level and among those working daily in the greenhouse.

Greenhouse production often relies on the knowledge and the practical experiences of the grower. Greenhouse growers need a diverse set of skills to perform well in a commercial greenhouse setting, such as Plant Knowledge, Growing Techniques, Understanding of Optimal Greenhouse Growing Conditions, Data Analysis and Problem Analysis Techniques.

The final greenhouse production is determined by the extent to which the growing requirements of plants and their physiological responses to their growing environment are understood. It is often forgotten by new greenhouse owners and growers that crops are living organisms that need specific growing conditions to grow well.
