Water cooled HID setup +rep

SO I was thinking of using this

with a 400 - 600w HID

what do you need to set it up? Water chillers? Water pump? and how much electricity would all this extra electronics require?

seems great for my small closet where the door should remain closed

if anybody has it set up id like to see pics too

i dont think water cooling your lights is necessary

Water cooled hoods have been around for years, but I dunno seems like they never cough on..

i would recommend vented because you will need a fan anyway to bring fresh air in and replenish CO2 unless you add CO2 yourself
