Germination

When a seed first begins to grow, it is germinating. Seeds are germinated in a growing medium, such as rockwool. Several factors are involved in this process. First, the seed must be active--and alive--and not in dormancy. Most seeds have a specific temperature range that must be achieved. Moisture and oxygen must be present. And, for some seeds, specified levels of light or darkness must be met. Check the specifications of seeds to see their germination requirements.
