See how many plants fit a row from your spacing choices.
Dividing a row's length by the in-row spacing gives how many plants fit down that row, then multiplied by the number of rows. Correct spacing gives each plant enough light and air, and deeper roots, so realistic spacing beats cramming more plants.
Plant Spacing
Plants per row = row length ÷ spacing; area per plant = row x plant spacing
