You will get argument on this, because technically growth does slow down, but I see no probleme with dark temps falling into the 60's, or even high 50's during dark. Mine regularly drop to mid 60's. Most strains being used commercially are indica doms, which come from a mountainous region where it often snows during the plant's life cycle.
