Darkness Required?

I run my autos on a 17/7usually. As @Justa_Retard says plants need to rest just like we do and 7 hrs of dark seems to work . So far..

Plants rest and heal during dark period. So 24 hours of light carries risk, but can be done.

Hi! I've not grown many autos yet nut from my understanding you can give her light as much as you want but 24hrs of light can stress the plant if there is no rest time at all. Autos dont need the darkness that much but there is some benefits in it too. I've also read that giving 12/12 lights might produce smaller yield or longer flowering. So you can keep giving her 24hrs of light if she seems to be happy or maybe give her few hours of sleep per day.
