Having big heat issues in my tent mid 90s

Please look at my set up. I have a decent inline filter that should pump enough heat out. I have a carbon filter.
My tent is about 3'x3'x 6'

What can I do here to get my temps in the 80s as the main rooms temp is in the low 80s.
I dont mind buying something better if I need. Please let me know what you recommend
.

Inside temps get mid 90s when the lights are on.

These Tents really only work with AIR cooled Lighting...

Even in 3x3 Tents with one light I air cool it...

We can run 6 Lights in a 8x16 tent with air cooled 12 Inch Fan, and a seperate 14k BTU air conditioner.

Always remeber EACH LIGHT CAN PUT OUT UP to 5000 BTU of heat ALONE, 1-2 in a small 10x5 Tent IS ASKING FOR TROUBLE if not air cooled.

I wont put more than 1 lights without AC into a tent... and no more than 6 with AC...
 
The answer lies in the final picture.
You have restricted your air flow by at least half if not 3/4 by the loop your ducting makes, thats almost a 360 it looks like. That is a lot of resistance believe it or not.
You need to redesign this part, plus if your in the 90s, get rid of the speed controller, should be at full power.
Is the little fan on the light blowing towards the bulb?
Why is your main room in the 80s? its March, so pretty much wherever you live this is a fairly cool time of year, what happens in the hot part of the year?
What size light? How many (looks like 1)? What size fan?
 
Starting with 80 deg air is going to be a big problem. My cabinet with a 400W hps and a 424cfm 6" fan runs about 5+ deg over ambient. This seems to be about the norm for most tents and cabinets, they only get warmer from there :cry:. I agree with Trueno about the vent piping too. As little restriction as possible is the name of the game. Every bend, twist, and turn adds up fast and creates resistance.
 
Ok, i made a mistake, my main room is far below 80- its currently around 76 and that would be the norm- awesome replies. let me go over a few and I wil reply but i wanted to set the record straight as far as my main room temp
 
Wheres your intake is it 8" at least??

I only see a exhaust and AE86 is right you have really hurt flow by having it sit on the shelf with two 90 turns... Honestly you should just be running full blast on that fan with no speed controller.

Awesome reply, thanks
I will redesign my duct and post pics when done. I have only 1 light and its a 400watt.
That little fan is pointed at the bulb.
 
So I made some changes and it seems the airflow is better but I will check when the lights go in in about 4 hours. I reduced the duct length dramatically on the first part but I still need to work on the other half but it did seem to increase flow.

So would getting a 6" carbon filter make the difference here? I have a 4" that I must use a reducer to be equal to the 6" inline fan.
you can see that in the pictures.

So is my problem that I don't have any intake fans? I always thought the exhaust fan can pull in enough fresh air from the vents on the bottom in my tent. Should I have a separate inlet fan? what size if yes? I run a 400 w with about 4 plants.

That reducer isn't helping.

he's right

plus yes you need a intake fan so you can seal those stupid flaps up so your lightproof.... BOTh veg and FlowR need Lightproof tents.

The fan can you hook it directly onto to hole the run the duct from there to the ceiling or down to the tent hole so it flows.. sorry i dont know if that description made sense,
 
I have the same size tent, with a 600w non-cooled hood. You need more fans to make the air circulate...

I use 3x 10$ fans and my temp stay around 82-83. I have 1 fan by the air intake (the flap) pushing air up and 2 others fans are on the other side (mid height) pushing toward the plants and
the "intake" fan.

That way you will get a great air movement....Or get a coolhood/ cooltube

Can anyone here show me a few examples of what I should buy for air cooled lighting? I already have the ballast.
thanks
 
If you can avoid reducing down to 4" that will make a big difference too without question. Your intake needs to be able to supply enough air flow to keep up with the fan ideally without creating and restriction, but maitaining negative pressure in the space. Does that make cense?
 
I would skip the hood for now and get a 6" filter, that will make a huge difference. You are in a tent so it is much harder to get away with no intake fan and still keep things light proof and cool, but it certainly can be done.
If you do get an air cooled hood i love my hydrofarm radiant 6"
 
Thanks everyone-
Yea I will go out and get me a proper 6"filter tomorrow and I have a good intake fan I can install.
Great advice from all and I will update here in a few days.
 
It is a "sealed" hood, no tube inside, just the glass with a seal, not the greatest seal but i have never had any smell escaping. I am pretty sure i got mine for $100 plus shipping, i am sure i can find a link if you need it.
