Definition - What does Calyx mean?
Flowers have a particular physical design that helps to support and protect them, while ensuring access to pollinators. The calyx is the base of the flower, the part that forms first.
In cannabis cultivation, the calyx, or calyxes (plural), is important for another reason – it contains high concentrations of resin.
The calyx is part of the bud on a cannabis plant, and is usually part of the larger cola, as well.
MaximumYield explains Calyx
All flowering plants must ensure that their flowers are protected, stable, and able to grow large enough to attract their preferred pollinators. The calyx is the part of the flower that forms first, and eventually becomes the base that supports the rest of the flower.
Within the cannabis calyx, you will find all of the important reproductive organs, including the pistil and stigmas. You’ll also find resin glands, which are responsible for producing cannabinoids, including THC.
In most instances, the bud that is harvested from the cannabis plant is primarily composed of the calyx, although the pistils are also included in most cases. This is because these two flower components contain the highest concentrations of THC. They are very important in nug-run concentrate production, but are rarely used in trim-run concentrates, which are made up of general trimmings and other secondary plant matter.
In a mature female plant, the calyx will grow, and eventually open to expose the pistils, which look like long, white hairs. In a male, this does not occur. Instead, the buds droop down and form pollen. Over time, the pistils begin to change color, moving from white to white/yellow, and then reddish yellow, before eventually turning brown and dying. The calyx should be harvested prior to the final stage (browning), usually after six to seven weeks.
The plural spelling of calyx is calyxes.
