I have a plant vegging 18/6 and usually my 6 hour dark is around midnight but I just found out my power company charges more during 1to6 pm so I was wondering if it was alright to abruptly change that 6 hour darkness to that time instead without causing damage to the plant?? Thanks for the responses!
i've had to change schedules many times in the past with no problems. if you're concerned about your bill, do what i do. i veg on a 16/8 schedule. works great!
Its better for them to get more light than less light than they normally do. You can change it to 24hrs on for a day or so until your new night schedule.
It's perfectly OK to change the light schedule, as long as... - during veg, you adjust by extending light or shortening dark, never by extending dark. - during flower, you adjust by extending dark or shortening light, never by extending light.
