That's the right way to do it.

Check out this earlier post above..
I changed it to that set up with negative pressure working but i only used 2 fans, one for the cooltube & 1 for filter , temps still were to high.
It seems there are many "Right Ways", i werent happy so added it to my main room were temps are controlled much better.Got Different opinions off another site aswell,but at least they posted pics of there grows and diagrams so i judge for myself.

I have 6 cool tubes and i push the air through all the lights i don't want all that heat going through the fan. but my room is sealed with co2 so i suck the air in and blow it through the lights and back to the outside world.

Set up sounds great man.. what strain you growing?

Alright vento.. good advice there mate,makes sense to me...also makes sure nothing gets sucked up and hits glass..
going to adjust mine 2morrow. + rep for takin the time to drop some decent advice

You are being a douche! Just because you and mike had a tiff on another post doesn't mean he is always wrong. he actually hit the nail on the head then vento said basically the same exact thing just worded differently and you +rep him. People who are not here to learn and hear other's suggestions should leave...check your pride at the door and realize that of the 1,000,000 ways there are to grow it what are the odds that you picked the best one? You were given one mouth and 2 ears so that you may listen twice as much as you speak.

Now that that is off my chest, if you put your filter in line with the cool tube you will need one hell of a fan to cool it effectively. It is best to pull the air across the light and not push and make sure your fan is located outside the grow space or it will exchange some stinky air. you will need to buy a seperate fan for the filter and either exaust it accordingly or set it to scrob

if you are pulling air you will be pulling the hot air into your can fan. electric motor hate to get hot they use power and wear faster. if your pulling air and god forbid your bulb breakes it will go right into fan and make a mess insead of just blowing out the vent. these are the reasons i push

Hi

I was actualy refering to what way round people put cooltubes ... Not the Suck / Blow thing .. But your correct ... a million ways of doing the same thing , Mike is correct for blowing ... I myself Suck



So this subject comes up a lot ... I went for something a bit differnent ... 1 passive duct into room to cool tube .... and one extraction duct ... with a T-Peice ... Bottom of the T connected to the exaust side of the cooltube ... middle of the T connected to a CF ... top of the T conected to ducting out of the room to the loft ... fan in Loft Sucking everything out


I cool my tube ... Have Neg Pressure in room ... and suck air thru filter .. so both Cooltube air and Filter air get sucked out of the room by one fan ... Clever ... I know



I check rthe air passing thru the fan and its slightly warm .... Fan can deal with that .

Hope that clears a few things up


Everyone just needs to relax ... love ... and be happy ... let's learn together

There are many ways to vent your room but 1mikej described the "correct way." Do you only take advice when someone draws you a picture?

What mike said for many reasons.

You do not want to add a filter in line with a cool tube as the filter reduces the air flow and does not allow proper cooling of the fixture.

You want the bulb pointing away from the air flow so the base of the bulb is cooled first.

A cool tube system should be sealed from the grow room, drawing clean air in and dumping clean air back out somewhere else.

If you set one up properly it will really help with the cooling.

Can you read ? well read my post back again.
Mike and Vento werent saying the same thing?
And i never said i had the best way or the Right way-

The more i think about it you one dumb guy !!, Pride is so far from the issuse .... lol 2 ears 1 mouth heard that when i was like 8.

Thanks for all the advice going to put right to work!!!!

I give plus rep for useful information...which is why Vento got + rep...
Sorry iscrog4food but this page anit for people like you ...

Good luck

cool NLX-- check this post ,it was my first or second reply.Theres a link to kicks thread, i think its worth reading.

Just to clear things up here..
The reason why i replied to 1mike the way i did was simple because hes " All wrong answers" comment. This is page asking for advice on cooltubes yes and if you check the first page the first post clearly states what mike said but with more info, check out the rest of the fisrt page all similar advice given. So "all wrong answers" doesnt make sense to me.As i said i aint the type to listen to some who claims to Know all the right answers. "push or pull does not mater depend on the fan manu.. " Who else agrees with that?

look at it like this: would send your kids to a football/soccer training /lessons with only the trainers word that he knows what hes doing or some actual proof like qualif/medal /players who done good etc .

I hope this clears it up for those that seem to think i have some thing in for 1Mike..Its not personal , and i aint into all bitchin on threads thats not what im on here for or about.

Good Growing..

hehe Nifty bit of explaining there Dr

I like that though , You took the time to come back here and try and clear things up , It's pretty easy for stuff to get lost in translation in text , Then you have the diffrent nations with diffrent ideas of whats funny and whats not

I was not actualy offended myself .. just wanted to be clear what the comment about the pic's was all about ...so that i could clear up any confusion about precived advice i may or may not have been giving heheh

But now i will give advice

The set up im useing works perfect , I have 6" ducting and 6" fan connected to the Cooltube and the filter by way of T-peice , My fan is roughly 10 METERS away from my room in a second loft ( To save space in the room and to reduce noise from the fan * btw the fan is connected to the roof beam that i folded a sheet of bubblewrap around a few times and my fan is virtualy silent *

I can cool my room down to 70 f on a cool day with the fan on full blast ... or turn it down to dial into a solid 80 f .... turn it down more temps go up ..its that simple .... I have a Negative preasure in the room so strong that if the fan is on full ... i can hardly open the door ( have to turn fan down to open it )

So if opinion is needed ...and i have to give it now .... My opinion is this ... suck ...BOTH with a t-peice

Am i right ?.... i dunno ... but im pretty fkn happy with how my thing works

Increace the Peace V

ps ... +Rep For the Dr ... for comming back to smooth the waters

pps , Just for the record ... Mikes a pretty cool guy and i doubt he ment any offence to anyone

Cool vento, yeah i like what your saying about the Tpeice. I ve taken cool tube out of tent now ,its in my main room with air just blowing through it. Got a new set up in my 2tents now 4 20ltr buckets DWC and 1 90ltr Tub DWC, Ive got 6" fans in both at the moment sucking air in,only just turned on the 600s 2 days ago so i havent added my exhuast yet. I just got my hands on ( http://www.growell.co.uk/p/1166/Futuretech-Acoustic-Fans.html ) for next to nothing thinking to get a 10" -6" reducer and a 6" t peice to exhuast both of them . Might have to add a dimmer switch when i think about it as it might just be a little to powerful..
Sound good to you? Going to post update of new set up.

Ive got my 12" fan wrapped in roofing insulation still in the bag just cut and taped to measure does wonders,and wrap the first meter of ducting in some silver spongy card thing not sure what its called but it all works to keep the noise down .

Some aircooled hoods caught my eye the other day only £70 think i might cop them next week or so .

Smooth waters is always better than bumpy waters!! Peace , love & harmony mi bredrin...As BOB would say..
Thanks for the advice V

Was going to create a new thread for this question but I'll save some clutter and post it here.

I've got a cab with dimension in 80x45x110 (cm) and I'm getting a 250W HPS in there. Because of space constraints, I wanted to do my filter/ cool tube setup in one rather than having one fan for the cool tube and another for the filter. I was planning on using the T section like vento suggested but that won't cool the light effectively.

My question is, if I have my cool tube set up (125mm inline fan/ 245m3/hour) sucking the air out and a passive intake going into the tube, will I need to still extract air from the cab? or could I just have a small desk fan in the cab circulating the air? Also, will the air from the cool tube have an odor from the plants?

one word of advise when referring to the post i made, I didn't draw that picture and it has one flaw in it. It says to PUSH the air through the cooltube and outside of your room/tent, but what you need to do is PULL the air. Pulling is always better than pushing when it comes to air. And WOWgrow you cool tube should not recieve any smell from your plants so long as none of your tubing has any holes or leaks. Should pull air in from one side and right out the other without ever coming into contact with the ambient air in your room so to speak. Also, i would add a separate fan for exhaust to help create negative pressure and to get fresh air flow in there so that all the CO2 doesn't get used up in the air in your cab.

cool kick.. I hear what your saying about the pushing vs pulling air,another thing i didnt do is add the 3 fans as shown in the pic,i only used 2 one for light and 1 for filter tried to have passive intake through vents. I think my problem was my intake air wasnt coming directly form outside .
Going to give another go when i get my hands on a decent aircooled hood. I should of done a poll on push or pull.

Wow i think kick said it all, never done a small grow so cant help much i would say though if you dont think your fans strong enough to exhaust both light an filter either get a larger one than can or use the one youve got now for filter and get smaller one for light.. What strain you growing?

Pull for sure. If you are looking for a good air cooled hood, I'm not affiliated with this site in anyway but came across it when i was looking on youtube at tent reviews... greners.com They have really cheap stuff, the tent I want real badly is the Secret Jardin DR150 and is 25$ cheaper than elsewhere for example. Also they have a good review on air cooled hoods as well which I just got done looking at as a matter of fact. Go with the sunspot or Radiant since they have the 90%+ reflectivity vs. the 85%. Grener's did a test and the 95% have 13% more light at the canopy, enough to make it worth the extra $20 in my opinion. That site is gold, excellent prices and video reviews on just about anything plus compatibility charts and everything. I've been studying it for the past couple days ever since I found it.

Oh, and I dont think you need 3 fans unless you really have some heat issues. Passive should be just fine combined with an oscillating fan, cooled hood with its own wind channel through your room, Plus the exhaust with the carbon filter and you should be fine. However, if you do end up needing a 3rd fan, check out the valueline fans at plantlightinghydroponics.com I've heard great things about them. + its $80 for a 435cfm 6in. not bad. Heard it was quieter then the 6in. 440cfm vortex.

Good luck and hope all that helps in one way or another!

P.S. Here is the direct link to the hood review. > http://www.greners.com/expertadvice/air-cooled-reflector-guide.html

Thanks for the advice kick. I went to the shop yesterday to buy some wood but just 18mm MDF boards were gonna cost me upwards of £60 so I just ordered a secret jardin DR80 with 400W HPS and 4" inline fan + CF. Dimensions of the tent is 80x80x160 (cm) so air cooled shouldn't be needed should it?

Cool..
Its a shame im in the u.k !! youve got some decent stores over there, i aint seen so many aircooled hoods in one place, never even heard of water cooled hoods!! thanks for the link anyway at least now i know whats available. Secert Jardins are ok ,ive got 2 Dr120s but they tear easier than i thought and corner pieces break easliy.Have duck tape handy and extra pieces..

Going back on there now..
