I always suggest with the blurple LED's to go between 40 and 50 watts per square foot of floor space. That's actual watts from the wall, not advertised wattage. Actual wattage is usually about 40% of what the advertised wattage is. 50w per sq ft is about as good as a purple light will do as far as adding to the yield. Anything over that is a waste.Mmmmmm... hell yeah.. that’s what I want.. then I don’t have to grow so many plants.. is my lighting sufficient??
