Difference between C. indica and C. sativa
There are several key differences between Cannabis indica and Cannabis sativa. These include height and stature, internodal length, leaf size and structure, buds size and density, flowering time, odour, smoke and effects. Indica plants tend to grow shorter and bushier than the sativa plants. Indica strains tend to have wide, short leaves with short wide blades, whereas sativa strains have long leaves with thin long blades. The buds of indica strains tend to be wide, dense and bulky, while sativa strains are likely to be long, sausage shaped flowers.
On average, Cannabis indica has higher levels of THC compared to CBD, whereas Cannabis sativa has lower levels of THC to CBD. However, huge variability exists within either species. A 2015 study shows the average THC content of the most popular herbal cannabis products in the Netherlands has decreased slightly since 2005.
