Your auto's are fine but they are best with indoor lighting as they require more light than standard photo strains that's why there a bit small they will soon start getting bigger with more leafs they get. What is your location so I can get idea of area.
very generalist response to light levels ALL over the world. I live in Los Angeles 34 degrees north of the Equator and I can assure you that 2 days ago on summer solstice day it was light at 5:00 am and still light out at 9:00pm . 14 hours is not too shabby. I don't know where you live or the OP , chadc , etc. but unless they are north of the artic circle I don't get your answer.
I hate to argue, but this seems like mis labeled advice. I have no problems with t5's , but as long as the sun is free , I get more than 12 hours of it , and I do, and the legal stature remains like it is for Medical patients like myself. I don't see it
