250w ventilation question

if it is actually that many cfm 2 will do for sure

Why don't u get the one of the inline fans from htg? They plug right in, and cost about the same.

If your talking about the duct booster I heard they dont give as much cfm as they say and the inlines are expensive but Im now thinking of just getting a 6in valueline inline for $93

I use that fan to cool my 400 watter so it should be more than enough to cool a 250. But Ur right, it is the duct booster ur thinkin of, and no they don't put out as much as they say. They pulled a sly one on that fan, advertising it as a 250cfm but it's REALLY 160cfm unless used with a 'booster' fan, THEN u get the 250. and ya those high power inlines from htg are spendy too. How much cfm is this valueline ur talkin about? Got a link for it?

http://www.businesslights.com/valueline-inch-centrifugal-inline-fan-p-2045.html seen a few good reviews about it

Which fan do you use to cool your 400w? the duct booster or inline?

also how close can you get to the tops Im hopin to get like 7in away with no burn hopefully

The 6in inline duct booster fans the one I'm usin, the one they say is 250cfm but is really 160cfm from htg, but I also have another 'booster' fan as well helping pull air out of the hood. Right now the tops of my plants are 6in. away from the glass on the hood.

The one in the second link is better than the first imo. I tried gettin a link to the one on htg but i can't get on their page for some reason tonight.

the 2nd fan is the same duct booster? are you using a cooltube or the euro reflector? I guess one of those duct boosters might do the trck

I got the 'solar six' reflector, which is damn close to the euro if not identical. I got two of these fans here, I ran one direclty from the hood to the ducting, then put the other at the end of the ducting as a 'booster' fan. http://htgsupply.com/viewproduct.asp?productID=46447
