cooling 2x1000 watts

Hey guys whats up quick question? I have 2 1000 watt lights and i am planning on using inline fans to cool them. i was wanting to know how many of them would i have to use to efficiently extract heat from the lights. someone said it would work if i hook one good inline fan to the lights and that would be fine...is that true?

ya, one big fan will pull enough air. you will notice a big difference once you start air cooling, it will be much cooler to the touch, and the plants will be comfy
