Grower's Secret, thank you for introducing me to your Grower's Secret Nitrogen. I started using it last December and WOW. Really WOW! I grow lavender from cuttings and from the propagation to 3" and to 1 gallon, you can see the difference. The appearance and color was spectacular. Thanks again for a great product.

I have found a high level of safety and security using the Grower's Secret products during the heat of summer. This is the time when golfer traffic is at its peak and everything has to be perfect. Delivering high quality putting surfaces is my job and the Grower's Secret products are a part of that strategy.

I will not farm without Growers Secret Nitrogen. We grow a wide variety of vegetables and herbs from melons to greens to root crops, sweet corn, and fruit trees. Growers Secret enhances size. fills out fruit evenly. The winter squash and melons are uniformly well sized well shaped. In the hydroponic setting because the product goes in to solution well the distribution and uptake is good and effectual uniformly. Powerful sophisticated product. Not just a regular nitrogen.
