These Fans Are The Real Deal !!

fullmetaljacket
All the intakes are from using coaxial fans,and being my first try at it.The dark room breathers are a 4 inch hole you cut,but the actually hole for air flow is only about 2 inches.Thanks for your input,i will design a new back panel and try that.Want to get things right before i start my auto hindu-kush.Will try and post a picture of my box.It not the best,but for my first try not to bad i think.It is mostly for clones to grow short.I have a white rhino mom,a thc bomb mom and aurora indica mom for my clone supply.

Actually a good amount of air that does not feel that warm.

well its only 4 degrees above ambient so it wont feel that warm.. Looks like your best bet is to lower ambient or plave the cab in a coller place man...

79 max though is actaully a good temp man ..any reason why you want tto lower it more? Weed tends to have a habit of growing like weeds and are pretty hearty... People in these forums are obsessed..myself included and this obession can kind of imply that marijuana is really sensitive. Based on you collection of mothers you probably already know this though..this for those newbs that don't.

I am by no means an expert so i would get other opinions. This thread is probably not the best place, create your own and people will help you out that know more than myself...

Thanks,that makes me fell better.and the obsession with lower temp,is that i keep reading you want it around 75.I really do not think i can obtain that temp,without lowering the ac to around 70 and then the power bill skyrockets.Thanks again for your help and time.Keep it real bro.

First try grow box and grow.
2 weeks old now,i think they are doing allright.

My test run is complete,and ready to start 10 auto hindu-kush for my first real grow.
Will post some pictures when they get going.


Everything i say is BS!!!

how much cfm would i need for a grow box 3'x3'4' using 400w hps lights/400w mh lights. i was thinking of getting the td-125 which has around 200 cfm. would that be sufficient enought to ventilate and keep my box in optimal temperatures?

Yes you would have enough cfm to potentially clear the air every about 10 seconds. Depends on many factors though, like vent runs, carbon scrubbers, light tubes, ambient, etc though to get a more accurate idea.

I think that fan though would give you alot of flexiblity for that size box.

Hey fullmetal thanks for all your input.The pics of my box are a few posts up.Check it out.

Box looks sweet Mindmelted, should start a grow jounel w/ some details on the cab..

Going to try and start one this week.Have a graet and high weekend fullmetaljacket

I'm going to be growing in a plastic storage cabinet measuring 25" W 15" D 58"H, with a 150w hps. The cabinet will be inside my closet (with sliding doors). I need to keep this reallly stealthy, with little to no sound and no odor. I'm thinking about getting the TD-100x fan and pairing it with this Dutch Breeze carbon filter - Dutch Breeze Carbon Air Filter - DFS2 | Air Cleaners/Odor Control - any verdict about whether these fans are acceptable for use with carbon scrubbers? There seems to have been some debate about this. If I combine this setup with insulated ducting will I be able to a) Keep my cabinet cool enough and b) have near silent operation with the closet doors closed?

I have no experience with those filters. For their size the cfm range seems really high. I have the same size filter (can filter 2900) and run the td-100. I am only getting about 50 cfm out of it on max though. I knew before hand this would be the case due to the PDF. I knew the filter created .20 SP and and from the pdf knew the td-100 was rated at 50 cfm at .20 SP.

Unfortunately i cannot find the SP or Pressure Drop created by the filter you linked to. Being that the cfm range is so much higher i would imagine it creates more SP.

Do i think the 100x will work, yes but you may only get 50cfm out of it.
The 125 is actually smaller tahn the 100 and pushed more cfm.
The 150 is a little larger and pushed alot more cfm.

Personally if you are determinied on that filter i would get the 150 and a 6" to 4" duct reducer. I would also hook it up to a speed controller so you can dial it down for extra stealth. But thats just me. These definitely work for carbon filters whoever said they don't is an ass. The numbers dont lie. Now what they may have "meant" is that the centrifgal or other model of fans are better because they loose less cfm when x amount of SP is applied. Well this may be true this does not mean these fans do not work as well. I just means you must compensate for their SP loss based on their size. The PDF makes this very easy.

Good luck

nice box!!! i saw one of those and thought nice box! i think imma get one and use i for a bud dryer!

Great info, thank you so much. I'm definitely not set on that filter, I just picked it because I thought it matched up with the CFM of the TD-100x, whereas the other filters I was looking at rated much higher CFM. But I wasn't taking into account the SP. I would rather stick with the TD-100 because I assume it would be softer than the higher cfm models. If you're getting good results from the TD-100 with the can 2900 then I will definitely consider getting that. Do you have any links to the can 2900? I can find the 2600 but haven't been able to find the 2900 yet.

Thanks!Got the box at sears.Using a 175w mh for veg and a 150 hps for flowering.Got a s&p td-100x for exhaust and passive intakes.Just started a auto hindu-kush run.

So any idea whether that TD-100 will work well with a can 2600 filter? I can't find the 2900 anywhere. The 2600 says the pressure drop at max cfm is: 180pa/. 75wg . Not sure how to read those numbers.

Yea sorry, i meant the 2600. I use the td-100 with the 2600 and it works great. Mind you the fan filter together are move about 50 cfm. And the pressure drop is .20 according to the can filter website not .75. Any filter with a .75 pressure drop will not work with this fan. If you look at the PDF i think the max pressure drop this fan is rated for is .40.

With you 10 cubic feet cabinet and 150 hps, this combo would do the job nicely. I use it in 48 sq ft flower/veg and am running a 270 t5 and it keeps my temps 2-3 above abmient with a 6 inch passive intake. My 270W T5 and 4 cfls probably puts out as much heat or more heat as your 150 hps.

Ok awesome. 50 cfm is fine with me as long as it's enough to keep my box cool - the box is 25" W 15" D 58"H with a vented 150w hps, do you think that will be enough? The specs on the 2600 say the max CFM is 94, but 50 is still alright? I guess it's mostly important not to go over the max because then the filter will be ineffective, but if you're under the max by a bit it is ok?

I edited my comment above.... but yes sir

Yes i saw that it was rated in the 90's on some sites so is the 9000. Not on the can fan webiste though and i trust their numbers more. It actually says 42cfm on the can filter website...i rounded.
