I agree, monitor or tv light wont hurt.. If they thrive under 24-7 light during veg a small amount of light wont hurt. Plants don't sleep they take all of that energy gathered during intense light periods and food uptake from the roots during this time.. and process the salts and sugars into The fruit. They grow at night small light is fine .
Daytime feeds foliage, night time makes fruit.. There always awake.
