How to Register for the Certified Greenhouse Grower at ProGreen

The Certified Greenhouse Grower (CGG) program is designed to promote high quality standards and professionalism for the greenhouse industry. Managing or working in a greenhouse requires an in-depth knowledge of plants, water usage, pests, chemicals, climate control, propagation and diseases.

Earning the CGG certification develops a higher level of knowledge and professionalism that benefits both the individual and the company for whom they work. To become certified you must pass a multiple choice/true-false exam with at least a 75% pass rate. To maintain certification status, individuals must re-certify every three years and provide documentation of their continued education and activities advancing their knowledge and professional growth.

There are three steps that lead to certification:

  • Complete an application that confirms your industry experience - at least 2000 hours of verifiable employment with a registered greenhouse, garden center, contractor, or an allied industry is required. The application must be submitted prior to taking the exam. The application deadline is February 15.
  • Attend six required virtual classes offered through ProGreen that prepare you to take the exam. Your participation will be verified.
  • Pass the exam with a minimum grade of 75%.
