Designing A Killa Cabinet - Input Greatly Appreciated!! - Page 9

Ok...

So I got a bit excited and decided there was *just* enough time before the game to put some caulking on this puppy. It was messy as heck but fine for my purposes.

I used one 10z tube and have a backup tube for when I affix the ducting and add the top.

Now I'm off to sit in a hottub with some ladies and root on the Raiders, yo!

GO RAIDERS

Looking really good so far.
You guys are doing a great job.

Don't forget to put something under it to absorb the vibration & noise.

You might want to consider either lining the bottom & about 3 to 4 inches up the side of the cab with something, or seal it with a really good water proofer, like marine varnish.
You wouldn't want to accidently mess up the wood floor under the cab.

Later Bro.
86.
BTW: Great choice going with a cool tube.
Are you planning on having an intake & exhaust fan hooked up to it?????

Thanks 86!!

I needed that boost especially after such a depressing superbowl

On the vibration - I was poised and ready to get 2sqyards of "ultimate" carpet underpadding (11/16ths) - I sat at the carpet station at HD for like 15 minutes ... twice! Looks like they put the real slackers in the home interior department because most everyone else was very attentive. I finally said to heck with it knowing that I'd be back in a week.

Good idea on the sealant. I bought Latex Flat White and a tube of fungicide - would the marine varnish work on top of a latex based paint? if not, I may look for some adhesive vinyl at TAP plastics or something.

Yeah... I'm pretty stoked about the cool tube! My friends at the hydro shop were really cool. They were so stoked about my cab that they special ordered it no extra charge! The owner said - "I suppose I could afford to order some other stuff from those guys anyway"

We talked about the pros and cons of three fan types:

4" axial 105 CFM
4" Inline 100CFM Centrifugal Fan
4" Snailshell 95CFM Blower

The bottom line was this - the snailshell won as they said it was the best for "sucking" air. We listened to them all and the centrifugal was slightly quieter but barely noticeable. They said the difference in 10CFM would be irrelevant as even at 95CFM, I'm seeing a full cycle of air in the cab every 3 minutes!!!

Pricewise, the snailshell was about halfway between the axial ($30) and the centrifugal ($140).

In setup, we are going to leave one side of the cooltube open and attach the ducting to the other. The CT has 6" holes so they suggested reducers for easier manipulation of the ducting and said that resistance of a 6" to 4" reducer would be miniscule.

The snailshell will sit on top of the cabinet and act as the exhaust fan. I was planning on either doing a distribution of 2" PVC lined light-trapped holes along the bottom as intake or just a single 6" circle cut with a trap similar to 86's.

I asked if the open side of the cooltube would contribute more heat to the cab but they said with such a powerful vaccuum effect occuring on the exhaust, no heat would be allowed to escape.

The cooltube should be here in about 6 days so until then, I will be working on painting the cab and maybe building a rubbermaid fluoro veggie tub as a side project.

I am now starting my research on DWC and am considering the rectangular rubbermaid roughneck 9x17x13(i think) with two lids - one with 6 x 2" netpot holes and the other with 2 x 4" netpot holes. But that's for another day

Thanks for your positive vibes 86. Brindie has decided to keep this thread active until the cab is complete and then move it to the library so everyone *please* bring-on your input!

Cheers...

I hate to add a negative note when I'm on such a roll but I really think it necessary to bring this up since we've all talked extensively about odor options.

I was given a demo of the Uvonair ozone generator and had a bad experience.

The salesperson plugged in one of the medium sized ones for me (3000cubicft) to demonstrate noise, vibration, scent, etc...

Well, this thing must have gotten a little too close to me or something because about a half hour later, I was really light headed and felt constricted in my chest... later a little trouble breathing (not life threatening but uncomfortable)

I read up on the symptoms of O3 posioning and was experiencing a number of things on the list. This was 3 days ago and I still have a small amount of tightness in my chest.

Now, I understand that I would *never* be in a situation where such a concentration of O3 would be that close to my resperatory system again but it did freak me out a bit.

I'm not totally discounting O3 generation as an option but want to make absolutely certain that I am not exposing myself to dangerous levels. This is *not* a paranoia post... and I will entertain any positive inputs here.

As I said above, it is still an option for me but I do have a special case of limited ventilation and the room is attached to my bedroom separated only by a curtain so I need to assess the situation because I didn't feel so hot after my first encounter with this piece of equipment.

It's a bit off topic but I felt it important to let everyone know.

Cheers...

I'm not sure how the uvinair ozone generator produces ozone, but if you get an ozone generator, you want to be sure to get one that produces ozone with an ultra violet light bulb. The other type, the ones that use corona discharge to produce the ozone are bad. They produce Nitrogen Oxide, (at least I think that's what it's called) which is a lung irritant that can cause all of the symptons you discribed. There was some info about this in one of the ozone info links I posted for you.
You never want to breath ozone in directly from the generator. That's when it's at it's strongest point.
Ozone only has a half life of 18 seconds, after that it turns back into o2 & co2. So by the time it gets out of your grow room & into your bedroom, it should be at low enough levels not to bother you.

I'm not sure if paint will stick to varnish. Next time your at HD ask them what their best product is to water proof wood.
I know there's some stuff called Dry Lock, but I think it's made for masonry. It still might work though.

The snail fan is a great idea.
You'll probably see a 265cfm Dayton squirel cage fan, (snail fan) on top of my cab before the next grow starts. For sure before I start growing my good genetics. With the 265cfm fan, you shouldn't need any other fans for the cab, not even intake fans.
You can order the 265 from Grainger for $69.95. I'm going to get mine at the local hydro store for $99.95. I know it's more $, but I don't like getting things of this sort shipped to my home.
As long as you don't find the noise from a 265cfm fan to loud, I'd go with the larger fan.

Later CD.

Hey 86,

The uvonair generates through a UV bulb. Guranteed it was my proximity that was the issue. I will never make that mistake again and I hope ppl reading this post understand that I am still a proponent of the tools but they should be careful handling and installing.

I will ask about the drylock stuff with my guys. Do you really think I need a larger fan? For what purpose? the cooling aspects? I thought a 3 minute full cycle sounded pretty impressive...

Truth be told, a louder fan would be an issue both for my sleeping and my neighbors but if there is a squirrel cage larger than 95 and smaller than 265, perhaps I can look into it. You are bang on with the prices - it seems as though in fans, every upgrade runs you about 20 bucks or so - 105CFM was 20 bucks cheaper than it's parent, etc...

I also agree with supporting local boutiques. I know that I will be paying about 20% more than if I ordered from various places over the internet... In this case, these guys are so nice and have been so helpful that I'd rather give them the money.

Plus, I know that if I hade any problems, I could return stuff without a hassle.

Thanks for your comments as always!!!

There's some weirdness going on with my account. It now appears that I have only made 29 postings when I'm well over 100 - Brindie is working to fix that for me. I was excited to make myself an avatar and everything but now I have to wait

Cheers

Agent86 · 01-27-2003, 11:14 AM

I have 2, 105cfm fans in my cab now. Both for exhaust. 1 for the flowering chamber & 1 for the clone/mom chamber.
With all 4 evls on in the flowering chamber, the temps stay around 81 to 83 degrees.

If your going to use the small squirell cage fan, you will probably need 2 of them. 1 for the cool tube by itself & 1 for the flowering chamber. I don't think that just 1 of them will be enough with a 430 watt hps.

Also, the advertised cfm of fans, is the max they can do.
They test the fans in an open room, where there is no resistance.
You will have some resistance in your cab.
To be on the safe side, I usually figure they will pull about 1/2 of what they say they will.

Later.

cali-canuck · 01-27-2003, 11:45 AM

Hmm... ok 86,

So what would you suggest if I want to be able to sleep at night?

(wwwwwwhhhhhhiiirrrrrrrrrrrrrrrrrrrr)

Should I do 2 smaller fans (more expensive - harder ducting solution to get to odor control mechism) or one bigger fan (louder? but less expensive)

Can I possibly *hurt* the plants by having too much airflow? Will I be able to keep decent RH levels or will they dry out with that much airflow?

so many questions ... thanks for your help.

hey 86 - were you rooting for the bucs? All us Raiders fans were pretty depressed. Good thing nothing major broke out in Oakland... although the media would have you believe it was a freakin' riot fest out there. A true example of Bowling for Columbine in action.

Cheers...

Agent86 · 01-27-2003, 12:26 PM

You can't have to much air circulation. Although I have burnt the leaves from having to much air blowing directly on the leaves, causing them to respire so quickly, that salts built up on the leaves causing them to burn.

As to the humidity.
Since your going to be growing hydro, you should have plenty of moisture. Do you know what the rh is in the room the cab is in?
The RH in my cab runs between 55% when the lights are off & 40% when the lights are on.
If the humidity gets to low, a couple of wet towels in the bottom of the cab should take care of the problem.

The hydro store I frequent has all the different fans hooked up so you can hear how loud they are & the 265cfm fan really wasn't very loud. Just slightly louder than the 105cfm axial fans I have.
My cab is in my bedroom closet & I don't think it will be a noise problem.
When I get the 265 fan, I'm going to build an air tight box on top of my cab to house the ozone generator & the fan. The the box will be placed directly over the holes for the exhaust of the flowering chamber & the cloning chamber. This way, the air will be pulled into the box, ozonated & then vented out into the closet.
This will give me more room in my cloning chamber & should be very quite.
Most of the noise from the fan is caused by vibration, so I'm going to hang the fan from the top of the box with a bicycle innertube. That should get rid of all the vibration & virtually eliminate any excess noise.

I was rooting for the Raiders, but I put a $500.00 bet on the Bucs.
Gruden knows the Raiders offense & defense as well as the Raiders do, so I didn't really think the Raiders had a prayer of winning the game.
I've been a Raiders fan all my life. The Pop Warner football team I played on as a kid was the Raiders. So I was pretty bummed when the bucs won the division championship. If the Raiders had been able to play just about anybody but Grudens team, I think they would have won the Super Bowl.
Oh Well.

But at least I won $500.00 bucks.

Later.

86, What a dilemma!

At least you were able to put aside your pride when you knew the money was gonna come in

I might have found some waterproofing options - they all seem to be for concrete as 86 said but some can be applied to wood and then painted on top. I will look into the price and toxicity of the Benjamin Moore version. Worst case scenario, I can by some of that vinyl the shops sell for reflection and glue that to the bottom.

I also found a 180CFM squirrel cage for 80 bucks (5 bucks more than the 95CFM) and the noise wasn't that much more noticeable.

Tomorrow I will post a pic of the pin system we are exploring for the door. Any thoughts will be helpful.

Cheers...
