I have used them and grew nice plants. Not sure what your beef is but someone elses thread isn't the place for it
I don`t have problem with Mars, but I have with manufacturers who don`t educate/are not educated and do false marketing to mislead buyers.
Plants will even grow under 125w CFL - so what? Its about how good/healthy/strong/bushy/tasty/smelly your plants are, how hight THC or CBD is, how big yield is etc. Its like a car - you can buy Daewoo Matiz or Ferrari - both are called "cars".....
