Salvia apiana - When to Repot

[Ishmael Fleishman]

I scored some Salvia apiana seeds last winter and planted them under lights and 7 out of 7 seeds germinated and then one died during transplant into pots. Now they are thriving. 

 

I love these plants - my first readings said they were hard to grow but I have not had anything but success with them. 

 

However, I got seeds from another seller and they were all duds with zero germination rate.

 

My question is when should I repot?

 

There are no roots coming out from the bottom - should I wait for that or is better to replant sooner?

^ I want one! 

I would defer repotting until necessary.
