I started plants by seed & have placed them in the ground. They are still tiny. I am in Southwest Washington State. Will 4 days of rain harm these little plants? Do they need to be covered?
It is best to wait until seedlings are several inches (2-3) high before planting them. They will have a hard time surviving harsh sun, pelting rain, bugs and bunnies. The fact that they are tiny indicates an under-developed root system for coping with outdoor conditions. But they might do fine! After all, many things are started outside from seed and manage to make it.
