A plant's appearance, size, growth rate, and many other characteristics of strain are hard-coded into the plant through its genetics. Over time breeders, have combined desirable genetics to achieve new characteristics, such as auto-flowering. You can explore the huge variety of strains in
== Flowering type ==
=== Autoflower ===
Autoflowering plants naturally have a short life span of around 80-90 days, in this time (given good conditions) the plant will go through the cannabis [[Life Stages|life stages]]. Autoflowers don't rely on light schedule to flower so they can be exposed to higher [[Light#DLI .28Daily light Intergral.29|DLIs]]. After harvesting it is not possible to re-
=== Photoflower ===
Photoflowering plants rely on photoperiod indicators to "decide" when to enter flowering. Indoors this is usually controlled by changing the [[Light#Light schedules|light schedule]] to include a dark period

A plant's genetics also has a huge impact on the cannabinoid content of the mature plant. Different strains have been bred to achieve a high THC content, no THC content, or even a 1:1 ratio of CBD to THC. There are many strains today that exceed 20% as a result of breeding for this characteristic.

The aroma and taste of Cannabis is created by the composition of terpenes and other aromatic volatile compound<ref>Minor, Nonterpenoid Volatile Compounds Drive the Aroma Differences of Exotic Cannabis - Oswald et al. 2023 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10601067/</ref>. While terpenes are widely known, there is ongoing research to uncover how these compounds define the aroma profile.
The most notable terpenes used to broadly categorize cannabis are as follows:
* Myrcene
* Pinene
* Caryophyllene
* Limonene
* Terpinolene
== Mutations ==
Environmental stress, among other factors, can cause the DNA of a cultivar to be altered causing a variation in its genetics. This can lead the morphology to differ wildly from other plants that began with the same genetics, in other words, the same strain.
==== Whorled Phyllotaxy ====
[[File:Whorled Phyllotaxy.jpg|thumb|300x300px|Whorled Phyllotaxy]]
This is an alternate arrangement of branching. In Cannabis, [[Anatomy of Cannabis#Node|nodes]] generally have two branches opposite each other on the stem they are growing from. When whorled phyllotaxy occurs 3 branches can grow from the same node.
==== Fasciation ====
[[File:Fasciation cola.png|thumb|Fasciated cola]]
Often mistaken for Polyploidy. This is the development of flat elongated stems. [[Anatomy of Cannabis#Cola|Colas]] with fasciation may have multiple buds at the top. Colas on fasciated stems will have more leaves than regular colas and reduced trichrome count.

* Lowryder. The ruderalis strain that all auto-flowering strains descend from.
