Roots Organics GreenFields is an ocean-nutrient-based growing mix designed for both the vegetative-and flowering phases of mature plants. GreenFields was designed with greater water-holding capacity, yet it is free-draining for frequent feeding of fast-growing, heavy feeding plants. GreenFields is a ready-to-use soil created with less perlite and pumice and specific ingredients such as fish meal and crab meal, worm castings, bat guano and kelp meal. Experienced gardeners know that a perfect outdoor mix is different than a perfect indoor mix and Green Fields has been proven as an excellent outdoor blend for your fast-growing plants. Ingredients: Composted Forest Material, Peat Moss, Perlite, Coco Fiber, Pumice, Worm Castings, Crab Meal, Feather Meal, Fish Meal, Bat Guano, Soybean Meal, Fish Bone Meal and Kelp Meal.
