Reasoning that they will still need the same number of hours of light each day, I would say yes.

That's what I thought, thanks for confirming my thoughts!

I usually try to start hardening off on a Tuesday evening after work for one hour in shade, 2 hours on Wednesday in shade, 3 hours on Thursday with the last hour being in waning sun, and then 4 hours on Friday in partial sun/shade if possible. These first four days they get brought back in and put under the lights. On Saturday morning I put them out for good on my east facing deck where I can keep on eye on them and move them around so they get good morning sun and maybe a little afternoon sun over the weekend. By Monday or Tuesday they should be ready for most anything but I will bring them in the garage in the case of sever weather. Be aware that once plants start to get exposure to outdoors they tend to start growing much faster so you will need to raise your grow lights when you put them back or you will probably find them growing into the lights the next morning.
