Types of Cannabis Plants
- Sativa: Generally grown outdoors with long, narrow leaves. It has higher THC content, often producing more stimulating effects.
- Indica: Usually grown indoors with wider leaves. It is known for higher CBD content, leading to calming effects.
- Hybrid: A combination of Sativa and Indica strains, blending characteristics of both.
- Hemp: Grown for its fibers used in textiles and other products. Hemp contains high levels of CBD and very low THC, thus it doesn’t produce a high.
