Cannabis sinsemilla also known as sensimilla, sinse or sensi is the female Cannabis plant that has not been pollinated and therefore does not develop seeds, increasing the concentration of cannabinoids and terpenes. This cultivation technique was developed in Sinaloa, Mexico, in the 1970s, by the drug trafficker Rafael Caro Quintero and consists of separating male plants as soon as they are known to be male, in order to avoid pollination of female pistils. The seeds are not useful for recreational purposes, and require the plant to make a great expenditure of energy that could be invested in increasing the tetrahydrocannabinol (THC) of the inflorescences (buds).
Cultivation of cannabis is the production of cannabis infructescences. Cultivation techniques for other purposes differ.
