What ratio of leds did you choose please? Looks like a lot of 660 there, i had too much 630 in mine I think (chose the same ratio as new magnum chromes use), I think the ratio used by grownorthern delivers the most impressive results of the apollo 10 model lights that I have seen. Im gonna order another with a diff spectrum and do a side by side grow before long but for the meantime im back to HPS.
