How much mix or medium will I need?

Whether you’re using our Classic Pots or our Transplant-inators, you might be asking how much soil mix or other mediums you will need. So…

…We’ve done the math for you!

We know that planning your grow includes a lot of calculations. Hopefully the chart below will help save a few minutes. These our are own calculations based on the actual dimensions of Grassroots Fabric Pots, rather than loosely based on the approximate gallon size. The calculations also assume the entire pot will be filled with soil.
