Indeed! When I said not on in daylight, I didn't acknowledge the fact that I'm always up to remove it at dawn - & vice-versa!
In several veg books it mentions growing under light and they suggest using a dual fluorescent fitting with one ' warm ' tube and one ' cold ' tube to give the necessary lighting spectrum.
