way to far away, but what size are your plants?

They will be a variety of vegetables from tomatoes to cucs to greens if they'll work. I may not need lights as I live at 7400' in SW Colorado with abundant and intense sunlight (and abundant snow). Rather than installing them directly to the ceiling, maybe I'll set them up on a cord and pulley system.

Mark,

I have shop lights in my GH but only so I can work after the sun goes down! If you can get 4-6 hours of decent sunlight most days of the week, you should not need any supplemental lighting.
