Athena AG's PRO line is a 3-part, dry, commercial cannabis fertilizer. The CORE is a calcium nitrate and micronutrient mix used in combination with either the GROW or the BLOOM depending on plant stage. Ideal for mixing stock tanks and compatible with all dosing systems. This large-grind mix is 100% soluble and will not clog fertigation systems or leave sediment in hydroponic reservoirs.
