When to transplant?

Hey. I started some seeds in a seedstarter kit from Lowes. The containers they are in are pretty small, so I am not sure when I should transplant. Any input?

when you see roots comming out of the sides of the pellets or whatever it is that you put them in.

Welcome to the forum. Be patient. They can go for at least a week or two before transplanting depending on light's etc. Some details of your plans may help if you want advice. It would probably be helpful for you to read some of the journals posted here to give you abetter idea of when to transplant.
