It's a pleasure to be involved, maybe it's just the genetics. I'm always in my tent during dark time and it never seems to have any effect on them and I have a orange light on my heater during dark so I think unless they getting a substantial amount of light I wouldn't worry to much, if you was out doors there would generally be light from the moon.. Well that's how I see it anyway.
Looks like she's got some nice buds on her m8, always next time for training. I see you took a cutting during flowering, I've done it a few times now and they really turn into some crazy Bush's , just seems to take for ever to get going.
Maybe you could try re vegging the girl you didn't take cuts off if you can be bothered. I got a gorilla glue that might need it aswell if she turns out to be a beast.
As for the long journeys you soon get used to it, luckily I travel with three other dudes so I'm only driving once a week generally, It's a killer doing all that travelling on your own.. must cost you a fortune in fuel.
