Cannabis comes in 3 sub-species, cannabis indica, cannabis sativa and cannabis Ruderalis
Most strains of cannabis available today are described as indica, sativa or a hybrid of the two.
indica is generally relatively short, conical with tightly packed branches, whereas Cannabis sativa can be described as tall with sparse branches.
indica plants tend to have short, broad leaves whereas sativa plants have leaves that are relatively long and narrow.
Its is important to get an understanding of each subspecies to understand the genetic make up of the plant in question
Cannabis Sativa
These narrow leaved strains developed in the warmer areas of asia where long summers allowed them to have very long flowering periods.
Compared to indica strains, sativa strains take a long time to complete their flowering process which generally takes around 12 weeks but can sometimes be even higher.
The sativa plant will grow very tall, given the right conditions, often reaching 3 metres and sometimes getting as high as 5 metres. The leaves as mentioned before are long and thin and the flowers (buds) are often very long as well.
Sativa strains tend to have very low levels of CBD but high levels of THC which means an effect for the end user which is often described as ‘high’, ‘trippy’ or ‘cerebral’. This is different to indica strains which tend to give a ’stoned’ effect leaving the user very lethargic.
