Grow Lights

Question

Is it ok to put flats of seeds under lights before they germinate?

Answer 1

They do not need the light until they germinate, but it will not hurt them to be under the lights before they germinate.

Answer 2

Providing your seed with the correct lighting conditions is as important as giving them the temperature and moisture they need. Some seeds do require light to germinate, some require darkness and some don’t care. Of course, you will find the light requirements for all flowers or vegetables on the back of their packets.
Here are a few flowers I know of that need light to germinate~
Begonias

Violas
Impatiens
