heat from 400hps?

i have 3 lights 1 1000watter and 2 400watters, but i only have one easy cool reflector. Im hanging them in a row in a 9x11 room. Obviously im going to use the reflector on the 1000watter, but the 2 400watters will just have the standard reflectors. The only form of ventilation i have is a 424CFM inline fan attached to a carbon filter. SO...
My question is how bad will the heat from the 2 400 watters be? I know they build up a lot of heat in closets, but in a wide open room will it be alright? I realy hate to buy 2 more reflectors, that would cost around $300.

bump......

You need more ventilation, what you have is a carbon scrubber setup. The scrubber isn't going to cool anything, so you will need to get a few more fans to pull and push air through the room.

are the ballasts in the same room? The reflectors are a good idea anyways you don't want to waste light.

yea, the ballasts are in the same room.
Im not against getting an intake/exhaust sytem, but i dont like the idea of drilling 6" holes in the wall

So the inline fan attached to the scrubber is not venting outside of the room?

The easy cool reflector, do you have that venting outside of the room?


If you don't want to use any other means of venting than what you have, I would suggest the following:

Hook a hose to the scrubber on one side of the air shade, which attached to the carbon filter placed high in the room.

Then another hose at the other end runs to the inline fan and vents out of the room.

That way you have the fan pulling in the hot air at the top through the scrubber so it's clean, going through the air shade cooling the 1000 watter. The hot air from the 400's rises and gets sucked up into the scrubber.

I think you should get more ventilation though. I'm a noob myself, but using what you have that's what I would do.

venting out the room is a problem because i dont want to drill holes for ducting. Is there a way to vent w/o drilling holes?
Maybe hook the ducting up to the air duct leading out of the room, but if the scrubber isnt completely killing the odor that might be a bad idea. Ive already spent like $1000 in equitment and trying to get this set-up without dropping another $300, which i quickly see hapening. O well hopefully the first harvest is a good en

you'll need to find a way to vent or keep the room enclosed and buy an a/c unit.

hmmm a/c unit sounds like a cheaper alternative. Do you know how much they cost and how many watts they usualy are? Cooltubes are expensive, but on the upside they cost nothing to run

how do easycool reflectors even work? do you need to hook a fan up to em?

The idea is to extract the heat created by the bulb before it gets a chance to heat the room (or make the glass hot, etc etc). So you hook a fan up to it...with some ducting...maybe a carbon filter.....maybe more ducting....and u remove the air from the room. If you weren't sure, those types of hoods (easy cool) have tempered glass.

oo, so the tempered glass stops the heat from reaching the plants and air is vented off to the side. So without ducting and a fan, the heat will still build up in the room?

so for every light i need a easy cool reflector, inline fan, and ducting? I have 3 lights lol Also wouldnt that mean i need to drill 3 6" holes in the wall? Or is there a way to put all 3 on one fan. Or for that matter do i need to cool the 400s or just the 1000watter

400 watters kick of a good amount of heat.
Try adding a couple more desktop fans that blow directly onto the lamps and slightly angle the reflector itself so that its easier for heat to escape from the hood,i.e. when you hang the reflector make sure that the end of the reflector that does not accommodate the bulb is about a half inch higher than the end that does

im taking air right out of the room.

the temps in the rom are about 70F so i figure it will work fine. Im also not trying to cool the air, just get it out of the room before it can heat the room. Unfortunitly as we speak i only have one fan, one filter, and one cooled hood, but i have 3 lightslol. Ive been considering buying a second 1000watter and selling the 2 400's because it would make ventilation much easier and cheaper.
--Or the thought ive had is just vent the 1000watter and the heat from the 2 400's wont be that bad because it will be diluted in the 9x11 room
Would that work, or would i see temps skyrocket

What if i drew air through the filter by the fan, and then split that air 3 ways to each lamp. The air would pass through each of the 3 reflectors and then i would duct them back together and vent out of one 6" hole. This way i would have to buy 2 reflectors and some ducting, it would come to around $400

Is there a way to do this any cheaper?

What about keeping the normal reflectors and buying a very strong fan to vent the entire room? for under $400 i could probably find a fan with around 1000CFM
would this control the temps directly under the lights enough?

Well Cool Tubes are not that expensive if you make 'em your self. In your case you are make a couple, so you will save a hell of a lot of money if you use the DIY in my signature. the most expensive thing you would have to buy is the Bake-A-Round on eBay, and that's if you don't luck up and find one at the Thrift Store/Goodwill. I feel your pain, I been putting together a cab for about a month. I just grabbed a 4" duct fan to blow the air through the cool tube. Its like 80-90 CFM's. Should be okay! I fell in love with the cool tube idea because it seems you have more control of the plant environment (Temps/humidity) inside the box!

Hope this helps!

alright guys i think ive got this figured out...
for intake im gona leave the window open a crack, there happens to be a window on the left wall and a bathroom on the right wall so i will bring air from outside through the lights and into the bathroom. There will be a carbon filter at the begining of the line so all air exhausted into the bathroom should be odor free, heres another diagram

window: carbonfilter-fan-D-lamp1-D-lamp2-D-lamp3-D :bathroom

ill get 25' of 6" ducting and cut it into 4 pieces

does it matter where i put the 1000watter? id like to put it in the middle
