Anyone Help me with this cool tube question pls!

[latewood]

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?

[latewood]

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

CLARIFICATION:::
Buk,

Those 40 CFM / 100 watts...

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
