I've got a big ass squirrel cage...but, I got lazy and put in a window unit...for 80 bucks, because the fans I want are going to run about a grand...
Somebody on these boards recently posted a formula that, I think gives a pretty good ballpark figure... I can't take credit (forgot where I read it...) but...
4 CFM/10 W
40CFM/100W
40CFM for every 100watts
What do you guys think?
I don't know...I will check and see if the formula is in the indoor bible...or 5 easy gardens...You guys should really look into getting these books, too!; I find they contain a wealth of info...I'll check.lw
Damn it I never knew those things took so much wattage... There goes the electric bill again

Those aren't 100watts to generate those 40 CFMs... no no no...
It reads::: 40 CFM needed, for every 100 watts of cooled lights.
So, if you have 200 watts of lights, you need 40*2=80 CFM to cool those lights...
In my setup, I'll have 1000W... so I'll need around 400CFM to cool the cool tubel... yikes!
LateWood::: Yes, I need to get books ASAP... it's just that,... my lazy ass... ;)
O K:dance: thats cool to know... Hey turtle do you think that light dimmer thing will work, thats a good ass Idea, if it does I would get the 465CFM;)
Damn but if I did the math right all I need is 160CFM for a 400w :) thats good. Damn Good Info Turtle:thumbsup:
Ill get back to you lot on the 105 cfm/400w cool tube situation tell you all how it goes. is it possible to mount 2 fans in the same line or does this cause problems?
cheers
im running a 1000hps with the bake a round cool tube set up with a dayton 465cfm and it is still very warm.....smaller room about 5x9 but i know i dont think the 465 cfm is even enough yet....thinking on adding others to it...just so u know my side
