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.

Cannabis Indica

Plant Characteristics
Indica medical marijuana strains are short, bushy plants with wide leaves. Indica plants typically grow faster and have a higher yield than the sativa variety. Medicine produced from cannabis indica plants have higher CBD and lower THC counts therefore a pure indica strain will produce a heavier, sleepy type of high. The flowering stage lasts between 6 to 8 weeks.

Plant Origins:    Afghanistan, Morocco, and Tibet.
