One of the most noticeable differences is their physical characteristics. Indica strains are generally shorter, with wide leaves and a dense bud structure. On the other hand, Sativa strains are typically taller with thin leaves and a more open bud structure.
In terms of flower structure, Indica strains tend to have a more compact and dense bud structure. This physical difference is due to the fact that Indica strains have a shorter flowering time and therefore do not have as much time to develop their buds. Sativa strains have a longer flowering time and therefore have more time to develop their buds, which results in a more open and airy structure.
As for the leaves, both species have seven to nine leaves and sometimes eleven leaves, although this is very uncommon. There is, however, a difference in the color of their leaves. Indica strains tend to have dark green leaves, while Sativa strains have lighter green leaves. There is a difference in color due to the levels of chlorophyll in the leaves, with Indica strains having higher levels of chlorophyll due to their shorter flowering time.
