The Tetrazolium Chloride (TZ) test, often called the quick germination test, is a chemical test used to determine seed viability, and results are usually available within 24 to 48 hours The TZ test differs from a germination test in that the TZ test can give you an early and quick snapshot of seed viability but is not a replacement for the more comprehensive seed germination test.
Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ.. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.

Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds ) to be eaten raw or cooked ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...

This procedure starts a few weeks after sowing, with the harvest of the leafy tops only. As a consequence, the plant grows new tops which will be multiply leafy tops in most cases and they can be harvested later on. If the plant grows on until seeds are ripe, hemp seeds can be harvested. Thus, harvest for juice and harvest for seeds are both ...
