600 Watt Cool Tube/ 2'x3'x5' Tent/ Kush & Cheese - GreenhouseSeeds

[GibbsIt89]

idk it seems like alot jammed in that little space..... simple! less is more ...... the size of your duct is a bit of an over kill dont you think?? i mean how many plants were you planning on fitting in it?

You should have gone with a taller flower tent. The one I use is almost 6 feet, which is just enough room to mount a giant ass fan and carbon filter like yours, plus light. Also, you should invest in smaller ducting inside the tent, just step it down to like 4 or 6 inches. The air will move faster and be louder, but will cool your bulb better. If you can, try to mount the filter and fan flush with the top of the tent, all the way to the back. That should free up enough room to mount your light in the middle without sacrificing much lateral space. And if you're worried about your fan pulling in broken bulb bits, just put a dryer sheet / coffee filter or two in between where the ducting connects to the fan. As long as you make sure it's fit properly it won't hinder flow or get sucked in.

You're smart for wanting to keep control over the grow. An inexperienced grower can ruin the whole crop in one simple mistake. I know I made my fair share of mistakes when I started out.

It def. is alot jammed in one little tent haha i agree. I had a hard time finding a smaller filter/fan combo, plus this one allows me to use it in a 5x5 tent still anyways for (fan/filter is rated at 190cfm together) when we flower our mothers. I plan to put 6-8 small clones (about 8-10 inches tall) into flower that are in 3L pots (small pots I know). And my ducting... its 6" ducting, probably just looks bigger. I need to get 4"- 6" wideners/spacers whatever they are called because my fan/filter is 4" and my cooltube is 6" ( i might just cut up some 6" ducting and make my own. So right now i just have my fan sitting on top of my filter thats sealed with some ducting tape then i have 6" ducting sitting over the 4" exhaust fan connecting to the cooltube. Believe me I know, I want smaller ducting for better faster flow, I will work things out (a little broke at the moment). My Tent is tall enough to do what you are saying because my plants arent that big. I'm going to fiddle around with things tomorrow and see what works best.

I WANTED A BIGGER TENT obviously haha but gotta keep the MRS. happy or I can't grow period right lol. Didnt want some huge thing in our bedroom. If it was just me and my bedroom hell id sleep on a single bed and fill my room with plants aha.

You guys want me to do filter to cooltube to exhaust fan eh? Isnt that dampening the full suction from the filter? THANKS GUYS!!! Appreciate your help and advice!! Cheers

Haha I definitely understand keeping the Mrs. happy. As a single bedroom apartment dweller with a 2x4x~5.5 tent in our bedroom, I completely understand! That's actually why I've had to make do with a 150 watt hps and cfls, instead of a cool tube and 400 or 600 watt mh / hps, but I digress.
I have just as big of a filter and fan, well, the fans in the mail lol. Don't ever try and get by with one of those dinky 100cfm inline duct fans, it doesn't work.
As for stepping the ducting down, it's easy. Lowes or your local hardware store can help you out for a couple of bucks. If you haven't already, invest in those metal bands you can tighten with a screw driver (Pardon my forgetting their name, it's my morning smoke time).
As for the order you set the fan, filter and light in, you got it right in your last question. It won't hinder the flow any having it setup like that. It's actually better to pull than to push when it comes to air. I wish I had my cool tube set up in my tent so I could show you how it would look.
Here's a picture of my filter in my tent with the 4inch ducting. With my ducting so small it'll be louder with the excess air movement, but I'll have plenty of room to hook up a cool tube hood in between the filter and fan.

Haha we have the EXACT same situation minus the higher powered HID and cooltube, haha its nice to relate with someone!! Ya i planned things out further after my last few posts. I agree that yes it is better to pull air than push air.. however it is better to push cold air over my light than pull hot air into my fan. I had to go and make a thread to ask what ppl thought of the 2 options. I received great responses leaning towards filter/fan/cooltube... It doesnt really matter actually though haha cuz I will be hooking my cooltube up to a straight cold intake from my window so there should be virtually no heat. My local hydro shop i think is my best bet, its closer than most hardware stores also when i did go to the hardware store all i found was regular aluminum ducting, I want the stretchy kind made out of that shiny reflective plastic that surrounds a wire.. easier to manage and rearrange if need be. I will still set my fan/filter up high like that though exhaust seperately out the top like you have it. And yes the 4" ducting makes for a louder operation however its worth it. Its ridding of the smell and hot air faster. Especially in a cooltube you want to maintain proper ventilation sizing to assure proper extraction of the heat.

And LMAO to the duct fan you have up. Im not laughing at you but with you because way back I had thought about attempting that as well except I was trying to find or make a smaller filter obviously. It was for a little cab grow with an LED panel.

PS if anyone is reading this and are doing a DIY mini grow.. its not hard to make your own cooltube right well its annoying as fuck trying to get rid of the stank cuz no one makes a filter/fan combo that small but I found what is called a "smoke buddy". It is a tiny little handheld carbon filter that you use when you are smoking out of your bong indoors and dont want it to stink so you blow your toke into the smoke buddy. This thing is perfect to use with a 4" duct fan or computer fan around 100cfm.

I really like the idea of pulling cold air in for your cool tube. I'm curious though, you mentioned above that it would be winter cold air being pulled in once that season gets here. Wouldn't the extreme difference in temperature harm the bulb? I have the availability to do this also, so if it's safe I'll be doing this once I get a bigger ballast.

That's unfortunate that your hardware store doesn't offer it. I'm lucky because mine is actually really well stocked with all kinds of odds and ends.

Hahaha all I do when I look at the little fan now is laugh. The idea of that little thing doing anything is a joke. I might use it for a diy carbon scrubber that I can fit in a window for when we smoke out our living room or for a small cab, haven't decided yet. I do like your idea with the smoke buddy. I've had a few over the years and they're pretty reliable.

Dude...you made a thread asking for opinions...the opinion you got from the guy who actually knows what he's talking about told you to pull air through or run seperate with 2 fans...you went with the ameteurs opinion because it was what you wanted to hear...LMFAO


Newbs crack me up!!

No, not really. He took the advice into consideration and decided to run a separate intake for the cool tube hood. Which, imo, is his best bet at cooling the most efficiently.

Have your giggles laughing at "newbs" I suppose, but other than laugh at him, what did you do to help him? I'm fairly certain the point behind rollitup is to spread knowledge and help others in their respective grows; not point and laugh at less experienced people.

Don't get it twisted...I don't laugh at newbs lack of experience...I learned everything I know on this very site...we all start out as newbs...

I laugh at people that "ask" for help but really just want somebody to tell them they are right...even when they aren't See it all the time

 

[MD914]

HAHA I will admit to this. I def. just wanted clarification, im not a newb, nore am i an expert. As you can tell I know what Im already doing though. SO i appreciate both your input.

MD914... you guys said the EXACT same thing, seriously read over both your comments again. The only thing that i corrected you on was that I DO have my filter extracting in the tent still. That was the only misunderstanding. So you were both right and so was I, thanx for clarifying guys, cheers!

I never said anything about your filter...I only said it was more efficient to pull rather than push air through your cooltube. To be honest it doesn't make a difference to me. I was just pointing out an observation...

My first big light I had my setup same as you have yours now...but that was then

Your right sorry I meant the guy from my ventilation help thread.

here is what that guy said:

you need to suck/extract the air if you only have 1 fan
if you push the air, you will cool the light but you will not be bringing in enough fresh air into the space

you need to extract air from the space to create negative pressure
this negative pressure inside the tent causes the air outside the tent to rush inside
this helps to stop air leaking out of the tent which also helps control smell
blowing air through the light will not help with this ^^

if you are ok with using 2 fans
you can use 1 fan to push cold air through the cool tube and straight out of the grow space
this will cool the light well and will not put heat in direct contact with the fan
also this will not need a carbon filter, it will create positive pressure in the cool tube
and ducting

a separate fan can be used to suck air from the space through a carbon filter
this will help control smell and create negative pressure and bring in fresh
air from outside the tent through a passive inlet in the tent

So I'm doing it with 2 fans.

I see what he means now in the beginning of what he has said. He is telling me that under normal temperature circumstances that I should have the exhaust fan outside of the tent sucking through the cooltube from the filter because im not bringing in enough air if i do it filter/fan/cooltube.

BUT, I don't get that, to me the fan is actually bringing in more fresh are if i have it filter/fan/cooltube because it is a straight attachment of filter to fan where the "better" way you say is actually sucking air through lengthy ducting and the cooltube so it would be drawing fresh air at a slower rate or maybe the same rate but causing my fan to work harder.

Again this is not normal temperature circumstances regardless if i did do it that way (filter/fan/cooltube), it technically would cool my bulb better as he says. Also how could i not be bringing in enough fresh air or not have negative pressure created? Its a 30 cfm tent and im using a 190 cfm fan/filter so im pretty sure regardless im bringing in enough fresh air. Did i cover myself on all angles here?

Please explain.

UPDATE: 1st Day of Flower!!!

So today was a tad exciting, I got my 600 watt MH/HPS digital ballast in the mail today with light hangers, 2 bulbs both MH and HPS, and a batwing reflector all for $145.00!

So what I did today was water all my clones and move them into the tent for flower. Still using my 400 watt because I need a 400 watt MH bulb to be able to veg with it, my 4" 100cfm duct fan for cold air intake from my window to help cool the 600 watt, and some 4" ducting which all comes Wednesday hopefully. So I have my 600 watt up for veg right now and got that crazy 1000 watt outta there! I will post pics at lights off tomorrow of the flower tent not that it really matters I guess cuz I will be switching the ventilation setup around on wednesday as discussed in above post.

I like to water one week then feed the next and so on. People feed once a week as their nutrient schedule usually says and some people feed twice a week. I might attempt watering and feeding in the same week so I will have to use less water when doing so.. so that it drys out fast enough, dont want to over water. We will see, might just do it with half of them.

I was suppose to water on Friday but instead.. on thursday I only gave them each 250ml of basic PH balanced water so they could survive till today to begin flower on something. They are in 3L pots and I was giving them 500ml everytime. Ive now bumped it up to 1L . When I "watered" I still gave them some nutrients this time:

-Mother Earth Bloom 3-2.3-5 @ 1/3rd of the dosage
-Voodoo Juice
-Grotek Pro-Silicate 0-0-3
-Grozyme

The Pro-Silicate and the Grozyme both say to use with every watering. The Voodoo Juice I added because it says to use the first 2 weeks of flower and first 2 weeks of veg. The Mother Earth Bloom can be used an additive or by itself. For an additive dosage it is 1.25-3.75ml per liter so I used 2.5ml per litre.

 

[GibbsIt89]

I will post pics of the flower tent tomorrow maybe or i'll just wait till wednesday when I rearrange the ventilation system and throw up the 600 watt.

Midwest Weedist had a good question about fresh cold winter air for intake in my cooltube.. ive wondered the exact same thing. My first question was will it pop because of the temperature fluctuation but i figured long as my intake fan for the cooltube is set on the same timer as the light I dont see it being a big deal. Anyone have any comments?

PS that air humidifier is awesome, gets my canopy to 40-50% humidity and 25-28 celsius

I'm just going to sit back and quietly watch while you do your thing

Please explain.

extracting/sucking air (negative pressure) is more efficient than pushing air when it comes to removing air from the space
negative pressure also helps control humidity better

if you push/blow air, (positive pressure) the maximum amount of air pressure the space can hold will need to be reached before air leaks out or is removed from the space

it is less work for a fan to remove air directly from the space (suck the air out) this instantly causes a negative pressure
air will flow in the direction from outside the tent to inside the tent
the result is the air is replaced quicker this way

imagine you have a fish tank of water its 3/4 full , you can add more water and keep adding water to cause the tank to over flow
this will cause water to flood out, eventually all the water will be mixed in with the new water

or you could suck the 3/4 full tank of water straight out and replace it with new water continuously

when using a 2nd fan to directly cool the lights it is ok to use positive pressure and it has advantages
but this is only when you are using 2 fans overall
one to cool the lights
one to provide air changes (co2) and control humidity

if you blow/push with the second fan

1 you do not need a 2nd carbon filter , the air through the lights will not come into contact with the air in the grow space because the positive pressure in the cool tube and ducting
keeps the air from the grow space entering the cool tube so no filter is needed less resistance less cost

2 the air space inside the ducting is small so the positive pressure can build up almost instantly

3 you can take air (cold) from outside and this will cool the lights more than sucking warm air through them from the grow space, some folk with lots of lights use an air conditioner to blow cold air through the lights instead of a fan blowing

4 the hot air does not come directly in contact with the fan

when people only use 1 fan, extracting makes more sense because the 1 fan is doing all jobs
cooling the lights, bringing in new co2, controlling humidity
using 2 fans separates the jobs between the fans

if you only had 1 fan pushing air through the lights
it would cool the lights quite well but it would not bring in new air very well or control humidity very well compared to extracting

I have a question...

I run my setup like this...

Carbon filter----fan----two cool tubes----out through the roof.

I have 12"x12" passive filtered intake's in the flower room wall and the veg room wall.

My fan has a plastic blade in it. Can that plastic handle the heat from the lights if it was pulling through the lights instead of pushing???

I still have negative pressure in my rooms but positive pressure in my cool tubes and duct's. If the fan can handle the heat, I would move it into the attic and out of the room.

Sorry for the highjack....

Sorry for the highjack....

My fans do just fine pulling...your filter may slow it down though. Why aren't you running two fans as the diagram above shows? That's how I have both my spaces (and how my new ROOM is being set up) that warm air isn't going to melt your fan...my ducting doesn't even feel warm...and I can put my hand on my cooltube while light is on...

 

[skunkd0c]

most likely the fan will handle the heat although as they work constantly this will maybe cause them
to not last as long , most inline fans the cheaper ones the hydro shops sell are plastic blades
i have a boxed fan this uses metal blades, maybe the mental ones have a disadvantage too
if they are not fully rust resistant humid air could damage them

the main advantage of pushing air through the lights with the two fan system is not having to buy another carbon filter which cost as much as the fan itself
not having hot air directly in contact with the fan is a bonus but not essential

these fans are designed to work in hot factories, the direct heat they extract from the light is hotter than this
but not so much it will damage the fan instantly , i think it would take time to show damage due to excessive heat
you could look at the spec of your fan and see what its safe operating temps are

peace

 

[skunkd0c]

two fan system is only needed for folk with heat issues/large grows or folk growing in confined spaces like tents and who want to keep the tent closed for much of the time
using the two fan system you should be able to keep a small tent closed
and at 75 to 80F with a 600w hps

most folk who do not have small space restrictions
or grow in an open room/space get away with 1 fan extracting doing all the jobs by itself adequately

So tell me something

I'm setting up a large room. I'll be running 3 lights in the row (cooltube enclosed hoods) and venting into my attic. If I'm running a 535 CFM fan do you think I can put my filter at the front?
(Filter-light-light-light-fan)

I have other fans of varying sizes that I can add at any point...

I'll also have an ac running in the room...

 

[skunkd0c]

I'll also have an ac running in the room...

i think that trying to cool the air down after it has been heated by the lights in the space is not as effective
once the air space is warm/hot it takes a very powerful fan to extract all this air quick enough to lower temperature quick enough

imo it would be more effective to concentrate your efforts on directly cooling the lights before they get a chance to heat the air space too much
you could connect some ducting to your AC then connect it to your lighting system blow the very cold AC air across/through the lights

nothing wrong with putting the filter at the front on the same line as the cool tubes
the main disadvantage is you tend to put the filter up high so it will remove smell and humidity also
and the heat of the room, but its also this warm air that you will be sucking across the lights
which will not cool them as well,
its best to have the coldest air possible blowing or sucking through the lights
the filter will reduce it a little but not too much

i have run 4x600w lights with a smaller fan than yours, but not in a tent

your fan is powerful enough for 3x 600w lights under normal room temps
and powerful enough to bring in fresh air and do all the jobs by itself in an open room during the colder times of the year
during summer when outside air is much warmer, or in a tent i would look at bringing in some fresh air from outside
or your AC to help cool things down

i do not think AC is that great for the space the plants grow in, as they only recycle air
they do not bring in new co2 rich air
and they cost a fair bit of electricity to run
