I have adjusted the light spacing for a veg light, king of thinking (200 clones, 400 veg and 600 flower)
so my veg light 75w / 3.76ft2 = 19.9w ft2 (400 par)
364w / 11.8ft2 = 30.8w ft2 (600par), average not max
I have worked out a way to build these without the bulb holder and this could reduce the cost down to £100 each
quicker to build and I can design them for any room size.
once its in my flower room with the reflective walls, the light spread will become more even, but there still things i would improve on the next one.
