Roots Organics Elemental calcium and magnesium supplement was specifically created to augment calcium and magnesium levels and prevent deficiencies that can occur with fast-growing plants. Elemental contains two absolutely essential macronutrients: Calcium, an essential nutrient for plant health due to its role in cell walls, membranes and other biochemical processes; and magnesium, which is a central component of the chlorophyll molecule. Supplementing calcium and magnesium is one of the secrets of expert growers and results in more vigorous plants and larger yields.

these products are amazing. definitely see the results and if your not careful you will burn them. the elemental (cal-mag) worked wonders. fixed my calcium def. and didnt have an issue with it again the rest of the grow. i will continue using these as long as i use soil.
I have since the end of this run purchased the entire line up from Aurora Innovations. the roots organics dry line will be what im using for the next few grows. until i run out of all of these 3LB bags... and thats going to take a bit. Huge fan. and would recommend and have been doing just that
Un grand plaisir de travailler avec cette marque la gamme soul me plaît vraiment bien elle est bien complète et les plantes non eu aucune carence .
