Resources for greenhouse growers considering organic certification

There are many Michigan State University Extension and national resources growers can consult about becoming certified organic.

In some markets that have more price plasticity, consumers are willing to pay a premium for organically-certified vegetables, fruits, herbs and plants. Therefore, some greenhouse growers that are supplying product to these markets are considering organic certification in order to meet the demand. Greenhouse growers who are considering organic certification will need to consider the following for organic certification: media that is already certified organic or media that is mixed with organic fertilizers and composts, organically-certified pesticides and methods on how to use them.

In order to get started in becoming organically-certified, Michigan State University Extension recommends the following resources:
