I have a friend that I'm growing with that keeps opening the door when lights go out for the day...

I tell him that it's not a good idea to do this when the plants are sleeping...

I've read on here that the plants need total undisturbed darkness untill lights are scheduled to go back on....

So could someone tell me if this is true or not...and tell me what could happen if they are disturbed when lights are out?
