No. There is no difference to the plant. They respond within a few days. The tops all turn a lighter green than the rest of the plant, then start stretching. Bruce bugby studied the gradual light change and found no effect. Same for the day to night change. No need to simulate sunrise or sunset.
I agree with boo. AC infinity has everything you'd need. Assuming you want led lights, I've used several brands of lights. Spiderfarmer, ac infinity, and mars have all been excellent. AC tents are incredible
