This 8 oz. bottle holds an amazing combination of micro-nutrients and elements necessary for maximum plant health. First off, it is important to note that this is NOT a fertilizer. Instead, you can use it anytime you fertilize, or, between fertilizing. You mix this product as directed with water and spray a fine mist onto the leaves. Spray-N-Grow penetrates the leaves, entering the plant, where it works with the plants natural functions, helping to maximize these processes. Just three weeks after starting on a Spray-N-Grow routine, you will notice wonderful results such as healthier leaves, bigger, more abundant flowers, and, for vegetables and fruits, a bigger yield of beautiful produce. This is a non-toxic product that will not harm any living creatures. For the best results your plants can give, mix Spray-N-Grow with Bill’s Perfect Fertilizer and Coco-Wet (a “sticker”): The Perfect Three!
