leds cob cree

Alrighty this will be my second DIY led flower light build the light will be built primarily for flower. But I'm using higher cct this time. So it could be used for veg too. But it will be my min flowe light in number 2 flower tent... and will be run through wireless switches from sonoff...

Had abit of a look around so I have a guide just unsure about volumes per room area ? Your views on the matter and knowledge is appreciated.
