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).
Neanderthals only existed between about 130,000 and 24,000 years ago, and can be thought of as an early human adapted to harsh Ice Age climates. They were relatively short (average height 5' 5'' for males, a few inches short for females) but well-built. In fact, mutual exposure between Neanderthals and early modern humans may have contributed to the folk mythological notion of a dwarf.
