Each bottle features 2 different components : The most complete micro blend in the industry, and a highly elaborate mix of macro elements. Of course, each is also buffered to avoid a big swing of pH in the nutrient solution. In both we include our Bio Essential formula as the micro base. It is the most complete of its kind, incorporating elements such as cobalt, hard to find in other nutrients, but also nickel, of prime value for organic growers as well as sub micros such as silicates. Total Gro, the vegetative Formula For a plant, the beginning of its life is very important. The way a plant is fed in that early part of its life will be a prime factor for the quality and the quantity of the future harvest. Total Bloom, the flowering formula A flowering formula should not be merely adding potassium, phosphorus and magnesium. The plant's needs in most elements, including the micros, necessitate a precise formulation of ingredients. The question behind our researchers' investigations was: what makes a plant produce an active compound, and how to improve that production? Many more elements than formerly suspected are involved in the process and by adding them to a nutritive solution, it is possible to achieve incredible results. Our studies led us to adapt our products to the latest discoveries. Flora-Series also benefited from this research and its formula has been readapted to these new findings.
