Internodal spacing[Internodal ˈspeɪsɪŋ]
Internodal spacing, or internodes, describes the spaces between the Cannabis plant’s nodes. The grower will have a concrete idea of how tall the plant might be by simply observing the internodes.
Plants with a lot of internode spacing will have longer, higher stems, but they may need to be staked throughout the bud and flower stages of growth. Branch bending and breaking are more likely with excessive internodal spacing.
To avoid excessive internodal spacing, one should improve the lighting system of the growing room. The internodal gap is thought to expand as the plant spreads its stem as it attempts to obtain more light.
