Lights on at night time (UK)

I was just curious what would happen if you had your lights on at night in the uk
instead of the day

I was just wondering as it might be safer as you are indoors not out at work college or whatever?

I know they have helicopters these days and if they fly over at night they could see the heat that is what I see as the con for it?

Please leave responses below?


BTW i am not growing just curious?

As this may help alot of people in the uk who are not aloud to grow(apart from the goverment haha)
PnP

 

anyone?

 

Ah ok Thankyou
