Fact : You get stunted growth from not giving a plant the complete darkness. even outdoor the moon shining is about max light for a dark period + light scatters in a completely different way outside than inside a growtent. Also you get a higher probability to get some first hand hermie experience, not necessarily tho. also the lightintesity differs a lot depending on daylight or moonlight or a hid light outside in the night about 15 meters away etc.
Why even try to argue with something that has been proven time and time again?
