Is 100Cfm enough for a GL40 with a 150w HPS in it?

Yeah - 100 cfm should be okay for 150w. But, for a bit of a buffer, I might go a bit bigger. When you slap a charcoal filter on it will lower the CFM. Something to consider.

So if i got a 6" 240CFM fan and charcoal filter would i need to get a 100cfm fan for intake?
