Maria Green fertilizers have been created by a Spanish company with years of research experience, with the goal of maximizing the potential of our favorite plants. They focus on achieving nutritional balance using high-quality ingredients, such as seaweed, guano, and humus. We tell you everything about this range of fertilizers available on our website.
Growth fertilizers
Maria Green is a line of growth fertilizers designed to promote healthy and vigorous plant development. These products are formulated with high-quality ingredients that provide essential nutrients. In addition, Maria Green incorporates microelements and amino acids that help improve nutrient absorption, strengthening the roots and improving the plants’ resistance to adverse conditions. Their product line is specifically designed for soil cultivation.
Roots
Roots by Maria Green is an organic rooting agent specifically for marijuana that promotes the vigorous development of secondary roots without the use of hormones, allowing for better nutrient absorption. This root stimulator is applied in the plant’s early stages, after each transplant, and at the beginning of flowering to expand the root structure, which results in accelerated growth of the aerial part. Its formula contains 0.9% organic nitrogen, micronutrients such as copper, manganese, and zinc, and 3% free amino acids, making it very easy to use and effective from the first crop.
