Indica strains tend to be the best for relaxing. A quality indica won’t make you paranoid; instead you should be feeling social. Indica highs are more physical than their sativa counterparts; these are the strains that make you sleepy, hungry, horny, etc. Kush and White Widow are great examples of some of the more popular indica subsets out there.
Indica plants tend to be short with a dense array of wide leaves. These are the plants you’d want for indoor growing (their lack of height makes maintenance, cultivation and discretion all much easier). The plant is a deep green and is higher yielding than sativa plants, partly due to the shorter growing season. The buds mature in less than two months.
