How to Use This Calculator

Enter the number of containers and each container's size in gallons.
Enter how many grow cycles you run per year — soil must be fully replaced each cycle, while coco and hydro media have different replacement schedules.
Review the Annual Soil Cost, Annual Coco Cost, and Annual Hydro Cost side by side to choose the most economical medium for your operation.
Use Cost per Cycle to understand the per-run expense and factor it into your overall grow budget.

How the result changes with Number of Containers

Number of Containers: Total pots or containers to fill with medium.
Container Size: Volume of each container in gallons.
Grow Cycles per Year: How many times you replant per year — soil must be replaced each cycle.
