  1. Tom Winrow

    As a USDA certified Organic aquaponics farm we have to be very careful about every input on our farm. And after doing thorough research on the limited number of OMRI approved suppliers, we decided on purchasing from Kelp4Less not only because they offered the best value, but they were also very helpful on the phone. After the first run of their products (OMRI approved Humic Acid, Kelp, and Azomite) we were beyond satisfied with their products (our plants were too!) and even more impressed by their impeccable customer service. We will continue to use Kelp4less to help us and our plants grow!

    Kelp4Less is turning the fertilizer and nutrient industry upside down, and we love it. Humic Acid goes into our own blend of nutrients that we supply to our plants, and the health and vigor of our plants are a testament to the benefits of making your own precision blends of nutrients. Kelp4Less takes out the guess work, and frees the industry from inferior big box store ‘balanced’ fertilizers. They allow us to control every input precisely, and Humic Acid is one of those inputs we absolutely love. Its also OMRI certified organic. We have no ulterior motives, we do not get any sort of compensation for loving this product, we simply love the availability nutrients kelp4less provides us. So much so, that we rate them a 10 out of 10 on our own website, Just look at the other vendors, we mercilessly tell you how it is, and Kelp4Less is top notch.
