Ok so I have a 6 bucket hydroponic set up. The set up is in a closet I have a 1000 watt light to it. I have my fan in side my room and I also have a big blower on the outside of the closet pushing air through the light to my attic. But still there was to much heat for my 1st batch.

Any ideas will be helpful

Sounds like an exhaust vent with a fan on a temp switch could work?
 
#3
Isn't that what my blower is doing when my light comes on my blower pulls air from out side the closet through the light and up to the attic
 
#4
The blower runs as long as the light is on but if that's not same thing where do I get one?

BB,
How's about some pics of your cooling setup? What are your temps in the closet? How about the adjoining room?

exhausting the heat produced from your bulbs, which im assuming is in a sealed circuit, is one thing. controlling the ambient temp of your room is another. yes, your light exhaust fan should run when lights are on but to control the ambient with a fan youll need a temp controlled fan switch. Try randmsupply.com or grozonecontrol.com.

im with TF, any pics?

I'm on my phone right now so not at house but I will explain to my best capability.

This is in my master bedroom the adjoining wall to my closet and room has a big blower mounted on it it pulls air from my bedroom which is pretty cool (hardwood floors) through. The vent through the light Bacc through the vent into the attic. I have a single 14 in fan mounted a single small dehumidifier. 6 buckets. 2 sets of 3. They have their feeder bucket outside the same wall as blower. Room is 4 x 6 max. Temp gets to 96

As soon as I get home I will get some pics it's unassembled nexus I jus harvested but the light and exhaust is still in tact

I'd pull room air (closet) in through the light and out with the fan. That way you're pulling air heated up by the radiant heat exchange from the light along with the other heat you're removing now. I do that in a small space with 1K lights and it keeps the temps mostly under 85. As long as my root zone temps stay under 70 the plants are happy like that.

This is the way you need to do it.

Ok but don't I need some type of air flow coming in and how do I suppress the smell?

I'm pretty sure that way is the way he is already setup with. Correct me if I'm wrong.


To lower the temps, you might wanna try giving your light intake from the outside air(keeping the exhaust the way I think you have it; out to the attic).
Now to keep the room cool add intake from outside and exhaust (which should be sucking hot air near the ceiling) to the attic. Also, you can insulate the exterior of your light reflector.

*Oh, if you have a chiller, that heat must be exhausted. Even it is in another room or something, it will likely affect your ambient temps. All my heat sources are partitioned off and exhausted.

As was said a few posts earlier...you need to pull warm air from your closet. You can pull it through your light but pull it from the closet (warm air). You "should" have a carbon scrubber on the exhaust to eliminate the smell...but...in the meantime..or in a pinch...
You're already venting into the (warm) attic. The warm attic air (smelly air) shouldn't come down into the living area since heat should rise. You could even vent up through the attic directly to the outdoors. This is a dangerous practice as the smell COULD be picked-up by a passerby...but..if it's venting way up high...
Anyway..controlling odour is a different thread I think.

For the heat issue...simply pulling cool air through your light tube and out won't cool your room. Suck (or blow) the warm air out of the room.

You asked about intake...you can just have a passive intake (ie-a hole lol)

out side the closet(buckets are being cleaned so they are in the way but u get the idea)

it comes in through the wall into the light here

then of course where it pulls out the air up to the attic

I couldnt tell by the pic but if thats an aircooled hood make sure the glass is on it for starters.
Secondly you want to pull the air through your light not push it.
Thirdly ive ran all options of vent setups in a tent, and if you have negative pressure intake then what worked best or me was to leave one end of the aircooled hood open in the closet, so instead of pulling air from another cooler room (which i was told to do at first) you are sucking air out of the room through the hood over the bulb then through your venting to mounted fan and into attic.

....so open end aircooled hood on the right side, ducting on the left from hood to inline fan mounted in attic (would be cooler) or on top of room,and more ducting to where ever you want it to go from there.

Since your fan is strong enough it should work fine...and no need for intake since the fan will be pulling fresh air in. If your worried about smell hook up your carbon filter to the open end side of your light hood in the closet and you should be good to go.

hope this helps...it worked for me.

I'm not sure I understand 100%. So pull the air from the room out to my bed room or up in the attic still?
 
#19
Up to you. depends if you want all that warm humid stinky air in your bedroom or the attic.

Point #2 from the last poster...not to confuse the op but...if you're running a scrubber...or...if your air for cooling lights comes from outside the growroom, into the ducting, through the light and back out of the room it's always best to PUSH the air through rather than pull.
If you pull you get negative pressure in the ducting and it WILL draw growroom air into it and expell it back out. NOT really what you want. I don't know if you can get ducting that doesn't have at least TINY holes in it.
When you PUSH air through the lights for cooling the ductwork has positive pressure and won't suck any smelly room air into itself.

PEACE

Buds,
alright first things first, you are gonna need to add some form of cooling for your closet, not just the light. No matter how much air cooling you have on a light, it still transmits heat into your garden. The people on here who have told you that pushing air through your light minimizes smells are correct. However, pulling through is more efficient, and draws better airflow across the bulb in my honest opinion. If you tape your joints, you are pretty damn safe. I've always had it that way, with no problem. I see that your fan is a 6" model. You should ditch the 4" duct for some 6". Mount the fan above the room, and convert your existing room duct inlet to 6" with a simple home ac air filter over the opening. If your hood has 4" flanges, I'd modify it to a 6" flange, or use an adaptor right at the hood at the least. Then the light is more proper for cooling, but the closet has yet to be addressed.I really think you need an AC unit. This will be the best addition to the room. Then the room air stays put, smells and all, while an AC chills it down to a workable temperature. For a $100-150 wall unit, you have plenty of AC for the job. You just need to see how you are gonna be able to mount it in. Can you cut any walls, or is that a no-no? Is this a rental? If so, you always can build a cooling box for the AC and run another fan like you have to cool down the back of the unit. I really think that is your best way to get that closet in control.
