My question is this: should I leave the grow light on 24 hours a day, even during daylight hours, or should I turn it off during the day? They do get sunlight during the day, but certainly not as much as if they were on my main living floor (but that won't work logistically, so the basement it is).
The Neanderthal or Neandertal was a species of genus Homo (Homo neanderthalensis) that inhabited Europe and parts of western Asia from about 230,000 to 29,000 years ago (the Middle Palaeolithic and Lower Paleolithic, in the Pleistocene epoch).
The Neanderthal extinction was the sudden disappearance of Neanderthals during a time when modern humans began to emerge in Eurasia. Since the discovery of Neanderthal remains, both the Neanderthals' place in the human family tree and their relation to modern humans has been hotly debated. At different times, they have been classified as a separate species (Homo neanderthalensis) and as a subspecies (Homo sapiens neanderthalensis).
