So called regular seeds. From such seeds, male or female plants can grow with a probability of 50/50.
This is the name of the male cannabis plants in Grover's jargon.
Regulars can be used to breed new varieties or to produce your own seeds. In addition, some prefer them because they are cheap: regular seeds cost less than feminized ones.
The content of THC and other cannabinoids in the male plant is an order of magnitude less than in the female. The target of most growers is “girls”.
