you'll be fine just make sure you throw it back into 18 hour days.

errr your talkin about the flowering plants huh, either way you'll still be fine just put them back on schedule.

buy a timer, if you keep it up you will have problems.

thanks man big help i just didnt know if it was going to stress them out, that our stunt their growth.
