Are LED Lights OK For Seedlings?

How far should LED lights be from seedlings?

What color LED light is best for seedlings?

This is where LED lights come in handy. Most LED growing lights offer both types of color spectrum lighting, so you can get all the benefits. TIP: Violet-blue light promotes plant growth and red light promotes plant budding. LED grow lights may look strange but they contain both types.

How many hours of light do seedlings need?
