Expert Tip
Triangular spacing allows you to fit roughly 15% more plants in the same area compared to square spacing, while providing optimal sunlight exposure.
Calculation Methodology & Details
Formula
For triangular patterns, vertical row spacing is reduced to Spacing * 0.866. Alternate rows are offset by half the spacing distance.
