Hi, I am with Optic Foliar and came across your post regarding foliar spraying. we have a product that allows you to spray with the lights on, no need to pH the spray solution and provides visual results within 24-48 hours. no burning or damage to the leaf will occur. I am looking for people to review and blog about my product. would you be interested? Please let me know and I would be more than happy to send out a sample pack for you. thank you, D13 www.opticfoliar.com
