I recently planted my herb seeds & purchased grow lights..Do I wait until the seeds emerge before I give them light? |
Yes. Once the seeds sprout they will need a sourch of light. Set the grow lights only about 4 inches above the tops of the plants, moving the lights up as the seedlings grow. If the light source is too far away from the plants they will grow spindly instead of stout and sturdy. Keep the lights on 14-16 hours a day. Best wishes with your seed starting project! |
