Help for the newbie

[VladTheInhaler]

High all, I'm setting up a NGB style growbox and this is what I've got so far:
1 closet l-76cm, h-76 cm, w-39 cm
150 W Phillips SON-T hps bulb, ballast & starter
homemade reflector
shitload of mylar (at least I think it's mylar)
digital timers, wires, etc.

Now, my probem is setting up the ventilation system, because fan noise is an issue for me (migraines), I would appreciate any thoughts on the subject.

Here's a link that'll show you how to wire a computer fan so you can plug it into a wall socket. Check out the other thread in this forum by "Red Greenery" He has a great setup going with PC fans as exhaust.

Holy shit, mastermagic, I like the look of that. Whats the flow rate needed for 150W hps, anyway?

i dont know my friend...i cool a 600 watt cab with 8 of these...and a small fan at the bottom of the cab(intake)

 

[VladTheInhaler]

Are those 82 or 120 mm fans?

 

[Guest]

this is not a regular pc fan it is a 48volt instead of the usual 12 volt

 

[VladTheInhaler]

How much noise do they make?

 

[Guest]

hardly none.....none...they are as big as a cd case

 

[VladTheInhaler]

Ha, found it! It's papst model 4318, 48V,100,1 CFM. It's an animal! A bit noisy for my taste though, 45 dBA is quite noisy for me.
Wahat temperatures do you get with your setup?

 

[Guest]

never above 80

 

[VladTheInhaler]

Hmmmm, 600 Watts, 800,8 CFM, thats 1,3 CFM per Watt, so using these criteria I'd need about 200CFM, or 4 PC fans + 1 for the intake.

 

[VladTheInhaler]

oh, i forgot, do you use a crbon filter?

 

[Guest]

dont forget my intake at the bottom....my pc fans exaust the air only(6 of them) 2 of them blow the hot air from the hood to the 6 exaust fans next to the light


no carbon fillter...i dont care abot smell....i love the smell of dank

 

[VladTheInhaler]

Love the pictures! However, I would use some kind of filter for stealth purposes. Anyway, I've got few ideas now.

 

[Guest]
