Here in Northern VA I located a hydroponic shop that had Azomite a 10 lb bag was $22 and the 44 lb bag was $42. At a farming store near Blacksburg VA a 44 lb bag was almost at cost $21 but a tank of gas was over $50 so off to the hydroponic shop I go. Since my containers have no measurable amount of trace minerals this should be helpful and will supplement the containers with kelp meal.
