Hydrobuilder offers the best organic nutrients. Our manufacturers use the top ingredients like seaweed, guano, earthworms, and more natural ingredients to help boost your plants. Whether you are brewing your own compost tea or just want to be sure your plants and product are all natural and organic you are sure to find what you need here on Hydrobuilder. We also make it clear which products are officially OMRI certified or simply organic. Shop by organic nutrient packages or individual organic nutrients and additives. We recommend using organic nutrients in conjunction with filtered water to prevent any of the healthy living enzymes and microbes to survive watering.
