We apologize but part of your question was cut off in your submission and we are unsure how to accurately answer you. Also, you mentioned using the product on orchids in a greenhouse but you did not specify what pest you are looking to treat for. We look forward to assisting you and finding an answer for you once we know more information pertaining to your question.
