What do think the minimal darkness that’s needed during veg for a photo plant? I’ve read a lot I’ve done the 18/6 for evey grow but would like to goto to 20 or 22 hours light for the last two weeks vegging. See any harm/Benifit ?

Photos need their rest and autos do as well. 18/6 is best even for autos.
