Can (and should) be sprayed with the lights on! No pH adjustment necessary. Amplifies any other foliar feed or pesticide when combined. Can be mixed with any fungicides and/or pesticides (Azamax, etc.) to avoid have to spray separately. When you do this, you only need to apply them at 1/4 to 1/2 strength. This is due to the fact that unlike other wetting agents, TRANSPORT allows the nutrients, pesticides and fungicides to penetrate into the leaf, allowing them to remain active for a longer period of time. It’s like using an IV versus using a pill – the substances are delivered quicker and more efficiently and have a greater impact. The only substances we do not recommend using in the same mix as Optic Foliar are beneficials, such as compost tea and other forms of bacteri and fungi.
