Yo guys. On my second auto grow. Started 4 auto purple strains on 6/21. Taking the wife to the city to stay for a night in late July. Will likely be about to switch over to HPS light at the time. I'm having a family member stay the night with my dogs and am gonna need to have my lights off for about 24-36 hours. Was wondering if this will stunt or hurt my girls? Any advice is appreciated.
