Multi strain fast buds

Day 15 and things are rolling right along.Ive just been giving ph water until the pots are dry.Noticing a lot of growth last few days and they are looking good.Ive decided to go from the 24 hour straight to 20 hours on 4 off light schedule.I have never really noticed much of a difference with auto flower from 18/6,20/4,and 24 hours on the light schedule.I think it is best for the equipment to give them a short rest time.I do like the consistency of the environment with 24 hours during the winter time though :)
