I was looking into upgrading my 250 watt HPs Magnetic ballast light to a 600 watt HPs lumatek digital ballast with a vented hood. My grow room is 3'x4'x5' and i have a 177 cfm vortex fan venting out. I was just wondering what size fan i should have to vent out the hot air from the 600 watt light. I was thinking about upgrading to a 245 cfm vortex fan but am not sure if i should go with a larger fan or not.
looking to upgrade my lights but need help

Your 177 ought to be just fine in that space. Its only 60 CF of air space, so the 177 is moving it well. You -could- move up to the 245 but prolly will not need to. No matter how much air you move through the air cooled hoods it seems you kinda hit a level where more is not necessarily better, its just noisier. I've used a 240 cfm to pull through 2 1000 watters in an 8'x10'x7' space and the plants seemed damned happy.

your fan is good for your space with the 600 hps upgrade, as long as heat doesn't become a problem, which it shouldn't with an aircooled reflector.
Im glad to hear that i don't need a new fan for the upgrade. I been wanting to upgrade my light for a while now but just was always worried that it was going to create a lot more heat. If i notice the temps going up then ill buy the 245 cfm fan but will not worry about it until then. Thanks for the help now i can't wait to finally do the upgrade and see how much more dense the buds get with the higher wattage.
