Germination is the process of starting the growth of a new cannabis plant, also it is a stage during which the seeds grow and the root emerges. Sometimes colloquially called “popping”, this process begins when the seed is exposed to water and light.
Proper darkness, humidity, and heat trigger the expansion of the embryo in the seed which takes from 12 hours to 7 days. Then, if placed in a suitable culture medium, the seed coat cracks and an embryonic root begins to push down.
After three days, the root is starting to develop and two rounded embryonic leaves appear, while the remains of the seed coat are pushed back. This is the start of the sowing phase known as germination.
