Marijuana comes in two basic types – Sativas and indicas. Which type you choose will determine the effects you feel. Each type has its own set of characteristics.

The sativa strain of marijuana is the complete opposite of the indica strain. Sativa medical marijuana plants are tall, thin plants, with narrow leaves, and generally are a lighter shade of green then their counterpart, the indica strain. Sativa strains take longer to grow, mature, and require more light. Medicine produced from cannabis sativa plants have lower CBD and higher THC counts which produces a more clear headed, energetic type of high. The flowering stage lasts between 10 to 16 weeks.
