So I'm going to be setting up an 8x4x7 tent with 2000 watts of air cooled hoods. I wanna get a fan big enough to pull threw filter threw hoods and out the tent.

Will a 10" inline fan be what I should go with? Or 12" cause I use a 6" in a 4x4 tent
I also wanna run a passive intake so I need the tent in a negative pressure to get the passive intake to work.

So you guys with an 8x4 what size fan you running.
 
Just bought my 1000watt digital ballast for $150 CDN has 5 year warranty.

So no input on my fan size EH?
 
6" unless my math is off
 
6" is enough but on the border with a filter on the end. I would go with an 8" and a speed controller just to be safe.
 
I have a tent pretty much the same size as yours and use a 6". I agree with P Jammers. It's a little on the low side. It's doing the job for me now but it does takes some extra attention. ie having to look in a few times a day on very hot days to make sure all is well.

Will upgrade at some point but just bought some LEDS to experiment with so the growing budget is all spent up for now.
 
My 8" fan arrived today man does this thing chooch it's gonna work well with speed controller.
 
The 8" Fan is SO strong on Full speed it pulls the vent towards the fan and collapses the vent. I am gonna have to hard pipe the first part of the Run.
 
Wasting your time, you are supposed to pull fresh air through the lights and not from inside the tent as that is completely defeating the object of keeping the lights cool as the air in the tent will always be warm-hot.
Now use a fan for the filter and one for the lights and as pjjammers says a 6" fan is more than enough providing you are pulling fresh cool air from outside your tent/room.

Peter did you read what you wrote?
So it's okay if just one light but 2 it defeats the purpose really . So let me get this the bulbs run at 150f+ and I'm blowing 75F air over the bulbs do you see the cooling factor?

Yes pulling cool fresh air over the bulbs is better but don't tell me my way is in effective.
Can I see pics of your Pro set up that you must grow awesome meds in right?

I'm an hvac r tech don't tell me how to vent
 
000Stank did you!! why are you asking such a question on air movement when you already think you know the answer being a HVAC TECH SPECIALIST which i assume you are not.
I understand your lights will be cooled slightly by your BAD method of pulling air through a carbon filter which i assume is situated in your tent but how on earth can you expect them to cool to a dialed in growing environment for MJ plants to thrive when you are pulling hot air from inside your tent and not from outside as would be a far better option-But like you say you're the expert.
I'll show you my set-up let me go take a picture brb.

This is my flower tent.
Does this meet your requirements for my groom to be considered a Pro set-up.
Btw the buckets with buds in is stable @ 49% rh and is ready for vacuum packing and weighs in at 17.5oz from nearly 4 x plants.:hubba:

I'm wondering where you read i mentioned it was ok for 1 but not 2 lights.
Re read what i wrote Slowly.:confused2:

Many many people run there exhaust by pulling tent air through their filter through the lights and out of the tent with passive intake, I have done it for years. As long as temps stay in check just carry on Stank.
 
Yes but i'm talking about maximum efficiency for cooling not what or cannot be done.

No you said it is a waste of time.

Read what you said slowly.
 
Dman i was referring to how air cooled lights are supposed to be used to maximum efficiency.
I run a 20Omm L1 linked to a Rhino Pro 200mm x 600mm L1 Carbon Filter and i use 1320 watts in my same sized tent and pull air from outside my house and exhaust into my attic so i have a little hands on experience of doing what he is asking so i'll just let Mr HVAC Expert learn his own way and learn from his mistakes.
Btw your grows are very impressive too, Pmsl

Actually they are, but you wouldnt know, many here do. I have many grows document on here that you might have too look to find, But I feel no need to justify my abillities to you, whoever you are. All i have seen is you running from thread to thread causing trouble, your a troll, they come, and they go. Have fun.
