Hemp, marijuana) produces male and female inflorescences in different plants (dioecious) and, therefore, plants are. Introduction · Materials and Methods · Results · Discussion Potter, D. The propagation, characterization and optimization of Cannabis Sativa L. Seeds are produced in female cannabis plants and carry the genetics of a male and a female.
The seeds need to germinate to sprout and a taproot will grow, which will become the taproot that anchors the plant. Cannabis seeds develop in the flowers of female plants after approximately 4 to 6 weeks after pollination. You'll see seeds begin to form in and around pollinated buds. Purposely causing a plant to become hermaphrodite is called self-fertilization.
Gibberellic acid or colloidal silver is typically sprayed onto the female plant. This technique is used to make feminized seeds and uses the plant's ability to be both male and female to force a female plant to produce male flowers. The pollen contained in these male flowers can only produce female seeds. Just keep in mind that feminized plants should not be used for reproduction, since they were produced without a true male, which makes them genetically inferior.
Healthy marijuana seeds are dark brown, black, or a combination of both. We recommend that you do not use green seeds. Green seeds are usually not yet mature enough to sprout. Both larger and smaller seeds will work.
Indica seeds tend to be larger in size than Sativa seeds. Another way that indica and sativa seeds differ is in their patterns. Seeds that are brown and black are probably indica, while seeds that are single color are generally sativa. Feminized seeds are produced when a female plant produces male flowers.
This is due to the introduction of light at certain times during the dark hours of flowering, or by spraying the flower sites of a female plant with colloidal silver to produce a chemical change in the plant that produces male flowers with pollen. For first-timers looking through the curtain to grow cannabis, autoflowering seeds are a good option. Once plants reach a particular stage (usually ten weeks later), they will begin to bloom. Growing an autoflowering seed requires only a minimal amount of sunlight to complete its life cycle.
For growers, this saves time and simplifies the process. Instead of allocating several hours of light and dark to their plant, they can relax and let the plant develop independently.
