Light height full power vs dimmed
Hi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

Lamp replacing
I replaced my current Viparspectra V300 300W led lamp with a Viparspectra V600 lamp 600W. I immediately replaced the new light with the old one. Do you think that switching from 300 watts to 600 can be dangerous for my girls?The conditions remained the same, the temperature and

Irregular light schedule.
I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her? My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.

If I move 3wk old S.Diesel & Critical from 18hrs💡indoors to outdoors where they'll get +/-11hrs direct🌞. Is there still a risk of them going into flower even though they're still babies? I really don't want this to happen. They'll be in the woods so no chance to add extra light

12.0v LED strip effectiveness
Will this mini led strip help my other weak light out? Or is it wasted energy. I’m still putting the plant in the sun as soon as it gets onto my balcony but while it’s really cloudy and in the evening this is all I’ve got.
