The short answer

Indica is a plant label, not a chemical one. It describes short plants, wide leaves, and a 7 to 9 week flowering window. Lab tests point to THC plus three terpenes for the calm effect: myrcene, linalool, and beta-caryophyllene. Strains that test above 18% THC with high myrcene get the most relaxation reports from consumers.

Terpenes that track with relaxation

Terpene levels shift with grow room temperature, harvest week, and cure time. Two batches of one strain can test apart by 0.5% or more. Ask for the batch COA before you buy.

How to pick one

Read the COA, not the name. Check three numbers: total THC, total terpenes, and myrcene share. A 20% THC flower with 2% terpenes and 0.6% myrcene will read calmer than a 26% flower with 0.8% terpenes. Inhaled effects start in 5 to 10 minutes and last 2 to 4 hours. Edibles start in 30 to 90 minutes and last 4 to 8 hours, so dose lower.
