Who ever owns a vented hood...cool tube..etc etc please help me out.. I know it will be diff but I was wondering what your light temp is running..

Im stuck on getting a cool tube or a Liquid cooled light..
I dont want to run hot or throw alot of heat off outside.. I will
be venting under my grow room to the out side.. AND cold times I dont want to show heat sighns..

What should I do.. Just a little help I need..The room is also sealed..SO I will be sucking fresh air from the atic and throu the light vented under the room to the outside..

A few Q's first...

Are you going to be filtering the air you venting out with a carbon filter? If you have to be worried about signs of heat, you probally will have to worry about the smell as well.

What size light are you running? The bigger the light, the more heat being extracted.

What size fan will you be running?

A 600Watt HPS can run very efficiently in a small space hooked up to a cooltube. Even after 12 hours running, the tube stays cool to the touch (With appropriate fan). If the ventilated air is being filtered, you can vent this heat right back into your home n the cold months. It will help on the heating bill, and you wont have a bunch of melted snow, and heat waves coming from your porche or cellar doors. Its actually a smart way to re-use your heat in the winter. If you have the right fan/filter combo, it will filter the air and it will be cleaner air coming out of your growroom, than whats lingering in your home already. With the right fan/filter, Oder will be the least of your worries. If you are sucking fresh air from the attic, you can vent your clean filtered air right up there too. In the winter it should NOT get too HOT in your attic as its usually FREEZING up there in those months. Hope this helps.pepsweetie.gif

Happy Growing,

personally i have used the CoolTube and loved it. drops temps significantly especially if vented outside the room. if you have a fully-vented Cooltube, your temps will stay at about the room temperature, maybe a couple degrees higher because of the light heat. so for me, in my small closet it was getting up to 85-90+. but with the CoolTube vented outside, and my house temperature set at 70-72, the grow room temp was usually about 75. personally i am also real paranoid about liquid cooled lights. i know they sealed off but i just dont like the idea of water around high electricity items.... maybe just the high paranoid mind

awesome see thats what I like to read and get info on. Thank you guys..

The room isnt close to the house... I will be running one 1,000 watt digital light.
Im looking for either a 6 or 8 inch tube and will be running a 400ish cfm fan..
Like I said I will be sucking the air from the atic of and will just vent it back out.. No filter i dont see a need to filter this air.?

Im going to be running c02 in this room so I need temps to be around 82-84 deg's then drop 10 deg's.. I will be running this @ night due to cooler air throu out the year...

Thank you for this useful info..

A coupla things

If you source clean air and blow through your reflector you won't need to filter that air for odor. however, more than likely you will need a second fan/system to vent your space....unless that is..you can control the temps without it.

I would be careful/think twice about exhausting grow room air into the attic....especially in winter. As it is usually cold up there...any MOISTURE will collect on the rafters/wood and if it builds up enough...could cause it to "rain" in your attic once Spring rolls around. There was a story of a grower who did such a thing and when it warmed up...most of his ceiling fell in...

not good.

good luck in your quest

Good Point about the moisture in the attic. Although I have never seen this problem. My attic is insulated, so maybe thats why havent seen any issues like that in winter? I vent the heated/filtered air right up into the attic and I have NEVER seen sweating in there? Mayber its the insulation that helps? I also would go outside after snowing all night and look at the roof. I never seen signs of heat on roof? I can DEF say this though, blowing a bunch of heated air out of the house in the winter WILL look obviose, or like a dryer vent -going for 12 hours a day? It will blow out heat waves and even look like smoke when its cold enough? Maybe if the air is vented Under the house, it wont be so noticable? Venting it out the side of your house in the winter? Too me, thats TOOOO risky? IDK I seen someone vent out of their house from unded the porch. All I can say is good thing he dont have back yard neighbors, cuz his porch is STEAMING in the winter? Just be sure to cover ALL your areas, so nothing SOOOO obvious is lurking outside your grow. If you are not worried about the smell, then you probally have nothing to worry about with heat signs? In my way of thinking though, if your neighbor can see the heat waves, then she most likely can SMELL the heat waves too? http://www.htgsupply.com/viewproduct.asp?productID=53961 (Check this out-590CFM fan WITH 8"Carbon filter combo for $290) IMO, Oder controll is an important factor in a stealthy grow. If your not worried about stealth, just the heat- then vent away my friend! IDK what size fan your looking at, but I use a 465 CFM fan hooked to a 600Watt cooltube, and it keeps my 3*3*6 space PERFECT! (Actually I have fan on speed controller and use it on Medium) The cab is only a degree or 2 higher than the room temp, and the tube is cool to the touch. Check out thier deals on Cooltubes also. I agree about the liquid cooled- SCARY! Too scary for my blood! Good Luck on your decisions- GROW SMART

Hey IM BACK.. Smell Im not wurried do to it not leaking out.. This area was well WELL done. From it being insulated and we used roofing tar paper and used it on the walls etc etc then used plywood... This area act holds the heat well i mean well.. I had some cfl's in there with the 4 inch fan trying to suck the heat out of the cab and the whole area was like 87 deg's steady lol..

Im trying to figure out where to vent this heat.. I will figure it out.. Your right the winter I dont want steam coming out of the area or if I vent it to the atic i dont want the roof to never have snow and there is like 4 feet out there lol.. But we shall see what happens...

Thank you for all the help.. I will let you all know the outcome of this..

Yo Gimmeeeee, good luck in figuring this out. I'm lucky, don't have any permanent neighbors (live on a lake where most folks come out a few weekends a month during summer). But to the point, I discharge directly under the house. Not exactly a basement, but more than a crawl space. I have 9 in flower in my 6' L x 3' D x 4' H box with DIY cool-tube. No steam and no smell. I don't have a humidity problem in the grow, and so I wonder why one would have a great deal of STEAM if one does not have too wet an environment in his/her box.

Best of luck to you.

Thanks bro.. I was looking at magnum xxxl light... I should make 1 of the cool tubes but fuck it.. I had some seedlings running but the plastic net cups fucked up and fell into my water system and the water was spraying up onto the plants and it brought them down and fucked up.. I just picked up heavy duty 3" net cups and I have more seedlings going in prob tomorrow wish me luck lol..

Cool tubes suck, the reflector is a joke.

I could NOT run my 600watt light in my 3*3 cab WITHOUT the cooltube. Im sure 600watt in a 3*3 room is overkill, but MY PLANTS LOVE IT and they never get hot. My temps are steady and never go above 80. My cooltube is cool to the touch even after running for 18 hours. My plants can get VERY CLOSE and not burn- This MIGHT make up for the reflector sucking? I would NEVER try to put this light in a small space without the tube. Once I get moved into the basement, I will try it without the tube, but for a small hot space- The CoolTube can't be beat!

Here is a thought about venting in the winter...

If you have a good filter, just vent the warm air back into your house. It will actually save on your heating bill. If the air is filtered, it should not stink. It should be cleaner air than what sitting in your house. If its filtered, dont waste heat in the winter! Heat the basement, or another cold room in the house with it. Its ALOT of wasted heat- In a recession, its almost throwing $ out the window- Or heat

I beg to differ, look at the shape of the reflector, it's 1/2 round.

The light bounces around too many times before exiting.

Here's a real air-cooled reflector.

The DayStar AC Reflector is super efficient with a cool running patented double-wall design, that lets it run up to 75% cooler than other reflectors on the market. It provides a HIGH level of reflectivity and a very even spread of light. It is compact and lightweight, weighing in at 10 lbs with a glass lens. Pictured to the left, this is the BEST air cooling reflector on the market.

Im just a Newb on my 2nd grow EVER? That diagram was Over-My-Head I must admit. I do not have professional answers, only Newb Experience with a CoolTube?

I don't have ANY problems with mine, and aint thinking of changing anytime soon? I STILL recommend it to anyone who asks, as I think ITS GREAT! I don't have professional answers to offer, but I feel I got some pretty professional results with it? Maybe Im wrong, and my Virgin Grow was not the best or professional looking on any level, but if thats the case, YOU COULDVE FOOLED ME? Heres my Virgin grow, from a Newb with NO EXPERIENCE, a cooltube, and a 3X3 cab. WHAT ELSE CAN I SAY? I have to stick up for the tube-Its did me good so far! (As you can tell, Im a Proud, Proud first time Parent- I HAVE to brag on em!)


Happy Healing,

I just recently upgraded my 1000 watt hps bare bones aluminum wing reflector to the hydrofarm daystar ac reflector. My light was previously 3+ feet above the canopy just to keep the temps at 84 F at canopy level. With the hf reflector and 2 low cfm inline duct fans I'm within 10 inches at 79 degrees. When I add a real blower fan to the mix I'll be able to nearly touch the plants with the glass. It's awesome. I love it. I should have done it sooner. The plants are getting a lot more intense light!

I didn't know that either, so when I looked at the diagram,
I asked him about it.
and he explained..

everytime the light bounces, more distance it added..
the farther away the light, the weaker it gets

Does that help?

sick!! I was looking @ the cool tubes for my 1000 watter.. I wish I can run it back into my house but it would look funny with a long tube running to my house lol..

I'm cleaning up the grow room this week I will shoot pics and I will just post them into here to show you guys what Im working with.. I have some stuff coming tomorrow so.. I will post pic's of my setup's also..

So what kind of " cool light " should i buy.. I saw the 1 just posted.. Price isnt really a wurry since I was going to spend the 250 on the other light housing without ballast..

What do you guys suggest on a light where the " Light " doesnt bounce as much and i get the full spectrum?..?

Gimmmme, I would suggest you run a larger sized reflector like the Cool Sun. Here is the one I use:

102309 012.jpg

Sunlight Supply: Cool-Sun Reflector. [RE806] - Reflectors, Hoods, Shields & Parts - Grow Lighting Systems, Fixtures, Movers, Ballasts, Sockets, Reflectors & Components - Horticulture Source

My set-up is an easy one. Intake is "passive" via a screened 8" hole that goes through the wall and draws air from the garage. The 6" Vortex fan draws the air through the reflector, and the reflector draws its air from inside the room. From there it goes through the fan and out a 6" flex hose through a 6" splice in the ceiling.

I am running a 1000W HPS, and my temps right now are running at 75 F. at plant height. The plant tops are about 8" from the glass. Rather than exhaust it into the attic, I added a roof vent to exhaust out of. The location of the exhaust is not visible from any direction. Large cedar trees overhang the roof area, and you [literally] have to be standing on the roof to see it.

BTW, if you are venting into an un-vented attic I do hope you are growing a non-aromatic strain..if you're growing one of the Skunk relatives it can get damn stinky up there! skunk.jpg
