Some will not germinate unless the soil moisture is above a certain level,…
What does a heat mat do?
Heat mats can both increase germination rates and help you achieve more uniform germination by giving you control over temperature — one of the environmental factors most closely linked with germination. They also decrease production time by maintaining optimal root-zone temperature,…
What is germination energy?
Germination is the awakening of a seed (embryo) from a resting state. It involves the harnessing of energy stored within the seed and is activated by components in the environment.
