Grow Light

Question

Hi I use a grow light to winter over my geraniums and lantana. How long should I have the light on each day? Is it better to run it at night or during the day? It is in my basement and not near any windows, so it’s strictly the grow light that keeps the plants going all winter. Thank you.

Answer 1

You can leave the lights on from 16-18 hours a day during the daytime and into the evening. Many plants need six hours of darkness.
