[3] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant. The leaves have a peculiar and diagnostic venation pattern (which varies slightly among varieties) that allows for easy identification of Cannabis leaves from unrelated species with similar ...
When the plant possesses seven sets of true leaves and the 8th is barely visible in the center of the growth tip, or shoot apical meristem (SAM), the plant has entered the vegetative phase of growth. During the vegetative phase, the plant directs its energy resources primarily to the growth of leaves, stems, and roots.

Further crosses will stabilise this trait and give a plant which flowers automatically and can be fully mature in as little as 10 weeks. Plant growing indoor under LED lights. Cultivators also favor ruderalis plants due to their reduced production time, typically finishing in 3–4 months rather than 6–8 months [citation needed]. The auto ...
