VEGETABLE OPTIMUM GROWING LIGHT LEVEL
Is there a publication that you can direct me to that will help me determine what the OPTIMUM LIGHT LEVEL will be for my HYDROPONIC VEGETABLE GREENHOUSE growing (tomatoes, cucumbers, green beans, snow peas, summer squash, and bell peppers)?
Thank you for your attention to this request. I look forward to your reply.
