What is the Optimum Propagation Temperature for Seed Germination?
The optimum propagation temperature for seed germination varies depending on the type of seed. Generally, most seeds will germinate best at a temperature between 68-86°F (20-30°C). However, some seeds have specific temperature requirements for germination, so it is best to consult the seed packet or a reputable source for the specific temperature requirements for the seeds you are trying to germinate.
Seed packets for most plants will typically include information about the optimum temperature range for germination, as well as other information such as the best soil conditions and light requirements for the specific plant species. Some examples of plants that have specific temperature requirements for germination include:
-Celery: 70-75°F (21-24°C)
-Corn: 70-75°F (21-24°C)
-Cucumber: 70-75°F (21-24°C)
-Lettuce: 60-70°F (16-21°C)
-Tomato: 70-85°F (21-29°C)
It’s worth noting that temperature requirements can vary based on the variety of the plant. For example, some tomato varieties require higher germination temperature than others.
