Answer 2

I wish that you would have expressed your question with greater clarity. For instance, you do not mention the circumstances under which the plants are used intensively, such as indoors or out, or if the matter of intensity is the fact of large quantities of the same species grown in the same area.

Please re-word your question and there will undoubtedly be many Answerers who will be able to help you with it.

Thank you.
