That's what I thought. Although, with the LED shop lights, I could provide more daylight hours than a full sun out in the garden.
BTW, I got my 4 foot long LED shop lights on sale at Menards this past winter for less than $10.00 each. They work so much better than the old light bulbs I used to have, and at a fraction of the cost to run. All I did was to make sure the light spectrum on the LED shop light was within the growing range for the plants.

Or, you can buy "grow" lights for $80 each in the garden center that do the same thing.
