curious2garden what is your 'Watts / m³' or 'Watts / feet³'?
I am using 460 Watts to light 528 Cubic feet on these girls or 14.95m³.

I ask cause your plants look like they are getting outside daylight or stronger.
Code:The formula for Cubic feet is: [COLOR=#800000]length × width × height[/COLOR]
Thank you, that is very kind. I'm using 1000 Watt HPS over 80 ft^3 = 12.5 watts/ft^3.
