How long do I leave the lights on? I live in southern California and the seeds are in a South facing window.

Hi Annie,

Are your plants in a south-facing window for direct sunlight? What kind of lights do you have on them? I am growing zinnias in my basement under T8 fluorescent lighting. Zinnias are not houseplants, and require more light than typical houseplants. One of my hobbies is breeding my own zinnias, and my indoor zinnia project helps with that. There is a relatively new book out on Gardening Under Lights.

Different plants have different light requirements. Specifics on that are covered in the book. You can use Amazon's Look Inside feature to see if that book might be something that would help you. These are current photos of part of my indoor growing setup using T8 fluorescent lighting on chrome steel shelving. I set my day length using timers on the lights.
