So the old style Mars Hydro LED says that is will cover a 2'x2' area in flower. Seems reasonable except that the unit is rectangular.... Anyways I'm really liking the light so far and so are the plants. My question is how "Deep" do they penetrate for decent bud quality? Should i lollipop my plants or remove some of the lower branches or just let them go all out? They are about 24-28" tall right now. Thanks!
