Well I managed to complete my mh lighting(not the prettiest but it'll do for now)I tested it with a bulb rated at 4200kelvin and what a difference

(I know not 10000k,but its my first time with mh

)
At first it wasn't really brite and took a few minutes.I haven't received the 10000k bulbs from Venki yet,but can't wait to see the difference.
Hope my corals do better(especially the gsp).One diy project done,lots more to go
