Secret Jardin DR60 with 400W HPS no cool tube?

Secret Jardin DR60 with 400W HPS (ballast in hood) not sealed and ported, i can get good airflow through the tent but im worried there will be a heat issue. I have always used sealed and ported hoods with separate ballasts and direct airflow. Will this light run too how for this tiny tent even with good airflow?

What size fan are you using?

your goint to need a strong fan ...........and it will need to be extracting the air tho the top port of the tent so u are removing the hottest air first and make a drawl up from the bottom to lower the upper temps

i would tell u get a 6 inch 400cfm fan for it your dr60 ( i own a dr120 and dr150)

if u have the cash i would honestly tell u replace your HID light with a LED ...........dr60 is not all that big so a LED light would get u the best results Hids are ment for something like 4x4 or 5x5 (the Hid lights get a bigger area of coverage vs LED but since u are not that big a LED light will get u the best results since the power is all in one area and it will get deeper into the plant then a Hid light would)

personally have never used LED's and know what im doing with the HID's and already have the gear. I have a 6" vortex fan that i used to use to cool a whole room with 5 1000w hps and im pretty sure it was only 450cfm, are u sure a 400cfm would be needed that is crazy strong.

The tent is only like 20 cf!!! that means it would clear the tent every 3 seconds......that is what i
will need?

anyone else throw some input in here? will i really need a fan to clear the tent every 3-4 seconds in order to maintain ~80degrees?

ment to say <80

I doubt you cooled 5 1ks w/ 450cfm fan. Vortex is my favorite fan and are superior to many other brands by far. How hot are you getting in there? I would always set up my tents in rooms that were being cooled (via a/c), or in the next room and push that air into the tent for intake.

Duct 5 1000w hoods together, make sure they are very well sealed. Put 6' vortex in attic. Run on thermostat at 76 degrees (on hot days may be running a lot but that is just more air for the ladies.) During the summer i would have to run the AC in the room the GR intakes from, but most of the year the normal temperature of my house was plenty cool on intake. Had 1 huge like 50lb carbon scrubber in the top of the GR opposite side from the intake, and the vortex fan in the attic would suck the GR's hot air through the scrubber, through the 5 lights and up into the attic. I had another fan that would exhaust the attic as it would get very hot up there (ballasts were all up there).

ALWAYS USE INSULATED DUCTING!

Also i think these 6" votex may be higher than 450, but thats what im seeing on websites too.

i knew something wasnt adding up so i went and checked my fans, i am totally wrong they were both 8" vortex. SO one sucking out of GR and one out of Attic, a lot more than i thought

hahaha i was soooo wrong they r the VTX800 so 750 cfm, a lot more sense being made!

Could i just throw a 6" to 8" flange on one of these bad boys and call i9t a day? or is that just gunna be way too much fan?

750 cfm .......in a dr60 .....................i like overkill but holy fucking shit

something that fast u can never have Co2.......(u can but the amount u would use would be 150 lbs in a month )

the truth of it is if u are not going LED ............then u should go a cooltube/hood system ................this would make your fan now work better and the heat issuse u are having would be reduced alot maybe enough so u are happy

small but big it should get u better controll over the heat just becuase all the air is passing over it .......so the IR heat it making is being removed

The tent is not large enough to have a ported hood. Basically i just need to go buy a good 6' fan, cuz running this huge vortex is just a dumb idea right? Would it work if i put it on a speed controller at like 40%? I can open the vent on the side of the light (like a port hole on one side) and put the exhaust duct right by it,think that will work, i figure it would get airflow across the bulb. If none of the above works i will be forced to put the light on 250w

your tent is it is just matter of finding the one that fits your needs .............the one i orginal linked yah was a 24x15 x7

this new one here is 22 1/2 x 12 1/2 x 7 3/8
http://www.amazon.com/Hydrofarm-DA6AC-Daystar-Flange-Reflector/dp/B000C21DOI

just keep looking u are not the first person to do something like this ................here i got it a cool tube 17 inchs by 16 inchs ..........yours is area is 24x24 it will fit
http://www.amazon.com/Hydrofarm-Wing-Cool-Light-Reflector/dp/B00J5UVZ32
and it uses a 6 inch ducting .................took me 15 mins to track it down


edit
if u are not running a carbon filter ...............your best cheapest answer is get that 17 inch cooltube and 2 6 inch boosters fans (metal fan blades 240cfm) run the ducting to the cool tube and put the ducting outside of the tent and hook on the booster fan to suck out ...............the 2nd one make a filter box and blow into the tent tho one of the lower posts ...............just rem what ever side the cool tube suxs on left or right the other side is where u want to dump your fresh air in

your area the booster fans/ intake filter box and cooltube ................i will stake my nutz on it that it will fix your trouble (aslong as the intake temp is somewhere around 69 70)

Thanks for your help. your advise has led me to what i think is going to work great. Like the first lamp u linked my hood is able to be ducted on one side, i just need to buy a 4" flange, which i now know exists thanks to u! After looking at my lamp i have decided i will be using a 4" vortex fan and ducting it straight to the hood and just pulling the whole tents air through the hood, through a filter and out the window or if the ac's on just back into my room.

the air u dump .............if u do have a window ac up push it to one side of the window on the other side get a peice of wood and cut it to fill the gap

u can get a vent like this
http://www.amazon.com/Dundas-Jafine-SEVZW-Soffit-Exhaust/dp/B002BHVWCA
(it is spring loaded when the air is not blowing closes up fits 4 5 6 inch ducting)...........i spray painted mine black and no one noticed it

but u just cut a hole out of the center of the wood fix in the vent then u can place the wood in the window next to the ac .............your exhust is dump outside and the air that is being cooled is fresh air before it goes into the tent and gets cycled outside of the house

i am currently doing this myself ............if u have a bush infront of the window where the ac is and vent is make sure u place something there to deflect the air (it will get hot and kill the bush i got a big dead spot before i figured it out)

hahaha ya the exhaust will be going out a second floor window so no defoliation required, or possibly into the attic if i decide to go that route. I don't have access to the attic, accept if i punch a hole in the ceiling, worried i may cause a moisture issue up there and big problems or the smell may go through attic into next door somehow. I have central air so no window units and im beginning to think i will just exhaust into my room and just run the AC a little more than i do normally in the room with the tents.

to get your best results u need to dump the used/spent air ...............if u want to allow a percent to leak back into the main room that is up to u but the mass of it needs to be ejected allowing u to pull in fresh air from the other area's...........this is how u take advantage of the fact indor has naturally higher Co2 lvls then outside ................quick break down Co2 is great during the lighted hours the plant uses the gas to grow 1000 to 1200 ppm is great for plants 1500ppm is deadly to humans ......when the lights go out the plants switch gears and they like Oxygen better (depending on your height sealvl to mile above is your oxygen if u are tall like denver some use oxygen to mimic sea lvl percents)...........but the plant will use what it can and dump out waste gases light they make oxygen night they make Co2 (different form then what they use)

so the air in the room needs to be dumped out just recycling it will end in low yeilds (it can be done but the gear to do it is more then your yearly income think space station oxygen scrubbers or bio domes )

ok if u dump into the attic i can tell u how to cover the smell ..............ozone generator
they make several kinds ones even made for ducting (but that is 8 inch)
i got thi unit in the room i live in i smoke cigs and weed and grow less then 20 feet away from there when ppl come over they smell nothing (to boot i brew moonshine for the drink and Co2 for the growing they can not even smell that )

thing is great i love it .........they sell cheaper models with dials and all but that little unit up where u are dumping the exhust air (run the system on Purity 5 ) and any smell will be gone in secs it like a fricken hostipal smell

im only worried about temps, i know in a 2x2x5 area i can grow good weight/quality with the genetics/light i have. Never used C02.

year of growing
Co2......... amount of water.............UV light (or finishers 10000k )

will get u the thickest frostiest buds u have ever seen ..........(feed is a factor but u should have dailed that in first few months of growing)

that cool tube i linked u with your fan on the ducting out ...........order a that 6 inch booster fan and fallow this how too Make a Filter box...........cooltube will make the air flow remove from the top part of the tent the hottest part along with passing over the bulb cooling it and the temp even more ...........the filter box will make your system a powered intake increasing the amount of cool air going into the tent (depending on the filter u use u remove everything bad for the plant along with a light block and bug block intake)

those 2 things will lower your temps ..............the ozone thing in the attic will allow u to dump the spent air up there with out worries of it smelling up the place ...............or u can get a carbon filter just have to match the CFM of the exhust fan to the CFM of the filter and u are good to go (u hang that at the very top of the tent sucks the hot stinky air out down then over the bulb then out of the tent ) .............just need to change the prefilter wrap once every 3 months and every 12 months u need a new carbon filter or replace the active carbon

the rest of the info was just for good karma

i have MANY more than 1 year of growing exp. It has also been a few years since i have done any cultivation and all my experience was in one room that a friend dialed in for me. No plans for CO2. I will be buying a carbon scrubber and just putting it directly on my exhaust fan and just suck the room out through the filter into my spare bedroom. And just have passive AC'd air coming in. Decided for stealth reasons i will likely just run the AC in that room on a thermostat and not bother bringing in or exhausting outside.
