Conversion for planting
I have this thing for chemistry and really would love some help.
Basically I have 120 ml plant cell and need to know how much soil to put in it. I intend to use the Dr. Earth Fertilizer (you can search it up on the internet) for my controlled herb group and it states: " FOR CONTAINERS: Use 1/2 cup per 1/2 cubic foot. (approx. 5 gallons) plotting soil.
Now I have converted my 120 ml (below is my work):
120 ml→120Cubic cm^3→7.32285inches^3→0.0042377cubic Ft
Looking at this it just seems like the number is too small. Can anyone help me with this.
