== Flowering type ==
There are two categories that define how cannabis plants enter the flowering stage: Autoflowering plants that "automatically" enter the flowering stage after a period of time, and photo flower plants that enter flowering based on photoperiod. The genetic trait of automatic flowering is made possible by breeding "regular" photofloweringphoto flowering strains with Cannabis Ruderalis.
=== 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-vegetate the plant again.
 
== Mutations ==
Environmental stress, among other factors, can cause the DNA of a cultivar to be altered causing a variation in it's theits genetics. TheThis can lead the morphology to differ wildly from other plants that began with the same genetics, in other words, the same strain.
 
==== Whorled Phyllotaxy ====

This inis an alternate arrangement of branching. In Cannabis, [[Anatomy of Cannabis#Node|nodes]] generally have two brachesbranches opposite each other on the stem they are growing from. When whorled phyllotaxy occurs 3 branches can grow from the same node.
 
 
==== PolyploidFasciation ====

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.
