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).
In particular, researchers have focused on the Neanderthals, a species very close in physique and brain size to modern humans. They once dominated Europe, but disappeared after modern humans emerged from our African homeland around 60,000 years ago.
