When i was fooling around with my ventilation one day, i noticed that putting the intake low on the floor on the opposite side of the room from the exhaust actually brought my temps down. You want the air to transfer across the room from the floor to the roof, throw that exhaust above the hood and as someone said, removing the humidifier will cool off the room a bit.

absolutely, treat it like a performance exhaust for your car, you cannot get your room to breathe without allowing it to exit as efficiently as it enters. Volumetrically they need to be somewhat symmetrical
I don't see any reason why a inline 4" wouldn't be enough, especially if you have two. I used a single 4" vortex for years, that cooled enough for two 600 w hps. Now I run a single 6" vortex, seems to work perfectly
BUT you do need to get an aircooled reflector in there, that's your ticket, you can get much closer to your plants that way, and we all know that the degradation of your light is pretty high, the further you get away from it.
Intake at lower end of room, and the exhaust at the top, in the winter you can play around with it if you have issues with coldness.
for example I flip mine when it gets cold, to where the incoming air is warmed by the bulb before entering the room.
Keeps the temps happy.

It's a 150w hps but plan on using 250, have a carbon filter it's just not connected yet

your tube is totally blocking the light man, get that thing as close to the end of the socket of your hps, treat it like it's creating smoke and you are trying to ventilate it.
Pretend it's like a bbq inside

so basically have my exhaust ducting sitting up higher in the room and not under the hood, should i move the intake ?

i thought if i put the exhaust ducting just under the hood at the bulb it would pull the hot air of the bulb?
Click to expand...
yes it will pull whatever hot air is in the area, but its far from optimal! Put the exhaust almost flush with the top and the intake across the room, no need to bend them down/up just sit them flat against the floor/ceiling. If its still too hot, then an additional intake/exhaust dedicated for the HID will bring temps further down. Right now im pretty sure your not cycling 100% of the internal volume because your intake is so close to the exhaust, and the exhaust is not mounted in the hot stale air part of the room (the ceiling). i get away without A/C and not only is my house hotter than yours, i use 1000w bulbs. Yes it does get into the 90's on a hot day though. No way around it without an a/c

I've moved the position of the exhaust ducting aswell as the intake but I'm no sure were to put it ?

Looks better. The exhaust, no need to point it up since you have a 90 elbow that wont allow a flush to the roof design. Just keep it straight and try to extend it to the zipper size of the tent atleast past the hid hood.

So now I have got the exhaust at the top right the intake fan pointing towards the bottom left and a 4 inch clip on fan, with the 150w light running the temps are reaching 85, 87 highest, still having issues ? Would a cool tube be worth the investment ?

Ok wow theres a lot going on! But here goes!

1.the inline fan should be pulling air straight from the hood of the light and exhausted out.
That in itself will create air suction from the lower openings in ur tent. Thats where the fresh air should be coming from.

2. Put the oscillating fan lower so that it shoots the fresh air up and keeping cool air low and the hot air up by the light so that it can be exausted out.

3. Get rid of the humidifier i dont see why u would need one but theres no need.
U can tank me later noob.bongsmilie

I've been told already to move the exhaust ducting away from the hood and to the top of the tent? Got rid of the humidifier and put the oscillating fan lower

Are you pulling in 80f air or something? How are you taking temp readings? Is the thermometer sitting under the light?

I think the intake fan is just no efficient enough thinking about swapping the fans to blow more cool air from outside, outdoor temps about 18c or even lower, will this work or just be a waste ? And the thermometer is sitting under the light

Take the thermometer out of the light and put it into a shaded area. Pulling air from outside will work if you have a dust shroom or intake to block bugs. The screen on your window will not do shit incase you decide to use that. Try to shade the thermometer first

I keep my thermometer hanging under the light so I know the temp at the canopy. Don't want to be burning any tops ;)

You can use something like dyna-gro protekt and that will helps the plants grow stronger and resist higher temps.

In a setup similar to yours, I have a carbon scrubber attached to a 6" inline exhaust fan that cools the enclosed hood. There is also a 4" intake to bring cooler air into the tent and blowing up to the light to cool it more.

I'm surprised that a 150w light is causing you heat issues considering what you're running for fans etc.

I actually didnt stop to think where you are venting your exhaust? Not in the same room as the intake right? A 12f rise is ridiculous with 150w. Just take the thing out of the light. You need ambient temps. You cannot read ambient temps under an HID. Even foliage temps. We all know plastic/glass heats up easier then plants.

Yeah I find the temp spike odd with such a small light.
Running 1000w I see a rise around 10-15 degrees.

Lol, I had to look at the pics closer to see if there was a ballast hiding in that tent.

the lights are off I have the intake running and a oscillating fan running and temp are at 24c, my intake is pulled from the left side of the window and the exhaust is pushed out the right side ? Is this a problem?

Even when temps are cooler the light still brings them up
