Explained: By taking the number of gallons in each pot and multiplying it by the total number of pots this will give you an accurate representation of the total number of gallons of soil.Formula: (Gallons per Pot x Number of Pots) / 200 = Total Number of Cubic Yards.
This will give Total Cubic Yards of soil volume in your container.
For example 8″ soil depth = 8/12 = 0.66 ft. We do so by dividing the depth in inches, by 12. Most likely the soil depth will be between 6″-12″, so we’ll need to convert this to feet.Explained: By taking the square footage of your bed and multiplying it by your soils depth, you will get an accurate representation of how many cubic feet of soil in your container.Formula: All measurements are in feet (Bed Length x Bed Width x Soil Depth) / 27 = Total Number of Cubic Yards.Then two formulas for if you’re growing in native soil you’ll want to use. So, there are two main container types and formulas for potting soil you’ll most likely encounter. We’re here to make this super simple for everyone, let’s take a look. But often times we receive the soil sample, we receive information about the clients cultivation site, but the soil volume isn’t there or isn’t calculated.
