What size intake fan?

[JakeKing]

What size intake fan would work in a small grow tent (1.2*.6*1.6) with a 600w cooltube running to a 150mm phat filter, the exhaust fan is a 150mm westaflex fan.

I'm looking at getting a 100m centrifugal fan to use as my intake as I want to keep noise to a min, but I'm unsure, any advice would be great

 

Thanks

Why not use passive intake? Would cut down on the equipment and noise

I second passive intake...

My set up is about the same as yours, I use passive intake.

I.E. hole in the side of tent, (with a short length of ducting) with a screen covering the hole, so no pet hair/dust bunnies get into the tent.

 

K.I.S.S.

600 watts in that size area is about 350 watts to much...The only thing that will get bigger with that much light is your power bill!

 

I run 2 X 150mm axials fans with only 250 watt HPS and thats only just enough airflow in summer.

Thanks guys, I never thought of using a simple passive intake. I think I'll use that method for now, does the passive intake work well in summer if the room the grow tent was in was 38 decrease plus+?

I was thinking about putting the 100 centrifugal fan underneath the house and running it thru a air vent into the grow tent in the summer months

 

Hey buzzo, yes you're right 600w is to big for that tent, but I'm kinda planning ahead, I can only use this small tent for the time being bcoz it's fits perfect in a build in wardrobe in my spare room, but I'm moving house soon and will get a 1.2*1.2*2

[loylty gets u nothing]

id peronally run a 250w centifugal for an exhaust

that way passive intake should rip threw

that way u sorted for the hotter months

remembering u need to allow for any corners and junctions and ofc pull threw carbon filter

running off a cool tube aswell u will need to use a splitter

u can get 1 that couples both 150mm to 250mm

air flow is supreme and u can never have to much fresh air

take care and all the best
