950 cfm carbon filter? What brand? Can filter? I'll figure it out when I get home and get back to ya.I gotta look up all the specs and calculate it out. So you have an intake fan too? Just an fyi unless the intake fan is the same size as the exhaust fan it's not doing anything. It's better to...

Tell me your fan cfm, duct size and length and fan model.

Just use some oversize flexible duct 6' or longer. That should quiet it down a bit.

Hmm sounds interesting. I'll have to look into that. So what's the benefits of plasma or ceramics?

Oh OK lol. Haven't really looked at it yet. Yeah its got the camera. Still gotta get the thermometer for it. Not sure if I'll use it to control the co2 yet. Is the opticlimate better?

I have Mitsubishi is he wall units for ac. Don't think I can make the opticlimate control that. Just have a programmable stat. Haven't even turned these things on yet. Just finished getting all the eye bolts in the ceiling, installing dehumidifiers. Now I'm gonna start hooking up the ac unit...

Yeah I got the opticlimate too. Time to do away with my timers and exhaust fan relays. I normally put 12 1000w hps in a room that size. In large hoods so it's like a ceiling of lights. I was told I could maybe get away with 8 dimlux so I went with 10, don't really know about them so I'm trying...

Cool, thanks. I'll be a little less than 24 sq ft per 1000 then.

Yeah, optimal footprint. Doing 2 rows of 5 in a slightly less than 12 x 20 room. They pretty much all criss cross quite a bit but I'd like to know what they are supposed to cover. 10' ceiling. I was told 4x6 but not found the hard number anywhere. And I'm assuming the 4' side is the flat side of...

Just got 10 1000w dimlux. Anybody know the light footprint for these things? They don't have any literature in the box.

Just the one fan will be sufficient.

You should be able to put it before the cool tube. Nothing should come loose from the filter. Or what I do is put the filter inside a duct. Then you can tap off of it to run duct to many lamps. Then of course its after the lights. Cheap little thermometers! I had one for a couple years...

Do you have a fresh air intake? In theory you should be pushing more air with 2 fans BUT if there is not enough air coming in for both of the fans they will fight over it and neither will move enough air. You can pull about 50 cfm from under a door. Any more exhaust than that and you would want...

100CFM isnt the most. A fan can pull as much as the duct will let it, if the fan is powerful enough. A big commercial air handler can literally collapse duct. Smash it like a soda can from the negative pressure. I have seen people say to use 400 CFM per 1000w for air cooling. I think they are...

Hell yeah! I am Union too Brother! I used some relays and photo sensors to turn my exhaust fans on and off. Then I realized I could have used relays to trigger EVERYTHING with 1 timer. You Sparkys got some cool toys. OK. IF everything is assumed we need to think about the BTU (heat output)...

I am an HVAC professional. You should see my ventilation system lol. Too many variables to answer. Is the duct insulated? whats the actual amount of air coming in. Because I guarantee you that fan is not moving 440cfm through a 6" duct. The 440 rating is without any duct connected to it...

My Regimen: Add fresh water daily. If they use a ton ( meaning your ppm is down 200 after you bring the water level up) add a little nute. Change every 4 days, some people say they go a week. Since changing every 4 days I have not had any root funk problems. The plants get more food and...

I root clones under four 40w fluro tubes (grow) from home depot. On 24 hrs. With Co2. Just popped roots in 5 days. My new record. Then they go under four 1000w MH, in the same room so they also have Co2. Hoods 3' or 4' off the tops at first. Dropping 6" per day until close. I pinch the tops at...

I doubt it moves that much air. If you look at the box to your fan it states that that fan moves 435CFM with NO DUCT ATTACHED, ZERO INCHES OF WATER GAUGE STATIC PRESSURE. Water gauge is how many inches the pressure of the air would push water up (or down for negative) in a tube connected to the...

Dont be cheap either! Spend the money on the additives but dont buy snake oil. I use General Hydros advanced schedule. Have found a couple things I like to switch out and something I call "The Secret Sauce."When you start running all the nutes your stuff will get way better. Ive only done soil...
