Indicas are short, compact, wide cannabis plants that require less space than Sativas. An Indica can be mainly recognized by its color and the characteristics of the leaf, they are dark green and wide (broad-leaves). Indicas originate from Central Asia and the Indian subcontinent: Pakistan, Northern India, Tibet, Nepal, Afghanistan etc. The inter-nodes of an Indica are short and closer together so that the plant appears very ‘bushy’. Also its flowers (buds) are very compact. The flowering period of an Indica is about 6 to 9 weeks. This means that an Indica is ready to be harvested more quickly than a Sativa.
Sativas are long, thin, high cannabis plants and can become very large (larger than Indicas under the same conditions). Sativas can be recognized by their bright colored leaves (this is because there is less chlorophyll present than Indicas), and by their narrow leaves. So Sativas need relatively more light to thrive than Indicas, this also has to do with their origin (they grow in areas near the equator, higher light intensity of the sun).
Types of Sativas can be found in: Jamaica, Southern India, Thailand, Mexico, Columbia, Africa etc. The inter-nodes of a Sativa are further apart, which is why a Sativa is often described as ‘stretchy’. Sativas fly to the heights, especially when they are put into flowering. The flowering period of Sativas is about 9 to 15 weeks, so it can take twice as long than the flowering period of Indicas (another reason why Sativas are not very suitable for commercial growing operations).
