Building a stealth Super Cabinet (at least im trying)

[nickfury510]

i got the td150 for a room that is 3w 2d 5h...

im still so up in the air as to what im going to do with my vent schedual...i guess it all depends on my home made cool tube running right...as far as co2 im pumping air in from outdoors so i dont think ill be needing a co2 boost.(but one really never knows untill your into the thick of it)...i would like to run on a schedual but im really concerned about temps...

sweet, how much was the 150? So you will be pushing 131 at .75 SP. So you will clear the room every 14-15 sec if you want too. Talk about overkill lol... Always better to kill it..

I like the Co2 but after some research, im nt sure it was worth it. I am surprised on how much the CO2 we generate when we breathe... I work out of the house, and in theory i could raise my co2 temps in a 12 x 12 office to above 2000 pretty quickly.....so if i intake house air i feel that my CO2 levels woulld be elevated. I think im putting the cabinet in my office anyway and running it while im working because people leave me alone around then and i wont have anyone over....

i think it was around 140 with shipping from an hvac supply house...

go look under filthy fletchs post until u find the one uner cooling sytem for grow room made out of styrofoam cooler ice and fan, the guy is a genius. check out his posts.imsure you would find somthing to help u.by the way i love your set up muc props too u man .

lol im definitely not doing that for so many reasons..but ty

i think i might build one of those....where i live we only have about 2-3 weeks of unbearable temps...it would cost a couple bucks in ice to run one of those things all summer..or all the time....

Hey FMJ,

I was thinking about your A/C problem and they have a type called a mini-split A/C. The compressor and air intake is on the outside of the building/cabinet and the blower connects to the compressor through an approximate 3" hole. I dont know if there is an air return to the compressor or not.

You could install the blower into one of the cabinet areas and have the A/C compressor outside. It would not make the cabinet more stealthy but could handle any heating issues. The ones on this site start at 9,000 BTU but by no means have I reasearched them in detail, I just have come across them before.

that thing is so unpracticle...$900 for a 9000 btu....you can get a portable madel with that rating for around $500....and you dont have to be a licensed h.v.a.c tech to hook it up....

Yeah nick but with a portable you are still venting smelly air from the grow room outside of the cabinet.

With this model I think that you do not have that problem although I am not completely certain.

you dont use a/c to vent your grow..its for cooling...there is no issue with smell where a/c is concerned...the exhaust set up is where you deal with smell

Nick,

A portable air conditioning unit is one that has the compressor, condenser and blower in the same unit. These type of units have to vent the hot air outside of the room they are in to work effectively. That hot air is drawn from the air around them in the room they are in.

A mini split air conditioning unit is one that has the compressor exterior to the room and the blower inside the room. The hot air is drawn from the ambient exterior air and used to cool the compressor. Fresh air is also drawn in and blown through the condensor and into the room thus cooling it.

The two concepts are different.

Now, I am not saying it is a cheap alternative. Nor am I saying that FMJ should consider this for his grow cabinet. I am only posting this as another alternative to a window or wall fan for people who need A/C for a stealth grow.

im still missing the stealth aspect of this unit....did you take the time to read the install details....and with a portable unit you would leave the unit out of the room and vent the cold air in..you dont want something else taking up grow space..

Whatever, I am not going to argue with you nick...

im sorry..i didnt mean to come off like a dick...im really just asking why this would be a benifit.....i guess i type aggrsive or something....

Thanks guys for looking into these. I though about these at first but depending on the make they still either add air to the room being treated or remove air from the room being treated. Additionally anything over 2,000 btu would probably be overkill. I have decided to actually just use my ventalation if i need to. I have been running a week now and my max temp hit 91.2 with the CO2. At that temp, i don't need any cooling.

I ran with for a week w/o CO2 and and just kept the carbon exhaust at like 100cfm 24/7 when the lights were on and allowed the controller to exhauset at night when Humidy got high.

If i do decide to resolve humidity and temp internally, i will go with.
Two Giant ThermoElectric Peltiers & Power Supply - eBay (item 200224934567 end time May-27-08 17:22:58 PDT)

That auction comes w/ 2 50w but i may add a third. I would need an additional 4" 100cfm fan to exhaust the hot side that would be in my util area. So the whole thing woud set me back maybe 250.00. They make fridges out of these things and wine collers etc. I only have 39cu ft - 6 cu ft for res - 2 cu ft for lights/vent = 31 TOTAL cu ft.

Thanks again for all you input though guys it is appreciated.

This is a great thread...

Keep up the great work!!

any pics?...........

Here is a rough of my first design. Cabinets are bought and on the way as well as a second fan. Let me know what you think. OH.. and I just do all soil. 400W hps for flower and a couple 4 tube 2' t-8 fixtures in the veg chamber.

Wow looks good man... Everyone has their own way of doing things and they all work, that is the beauty of it.

I would do the following -maybe no better than what you have

1. The carbon filter in the the flower cabinet. Could you maybe just put it above the shelve and have holes in the shelf? I was just thinking it would better use the space and eliminate that 90 right before the filter. You could even just put the ballast up in that area without its own chamber as well. BigBullballs or something has a similar design to what im referring to.

2. I think 12 plants may be too many. I would maybe do 2 or 3 at most and you yield would be the same or more. Less plants also means less trouble legally i believe in most places.
-If you do decide to do 12 plants you dont need all that height because you will have to keep the reallly small. I would even do two shelves of 6 with two smaller hps lights than go one shelf of 12.

3. I wouldnt waste using 2 carbon filters in the veg/mother/cab. Especially with one fan. Air pressure tends to flow the path of least resistance so you will have to play with it to get both filters drawing good amount of air. Having one up top and just putting passive vents into the floor and shelf will also allow you to simplify what appear to be complicated intakes. This will not decrease you exhauset quality at all...

I had trouble looking at your photo i would make it bigger so other people who know more than i can make comments as well. I think thats a great design and will work nice if you do it how you drew it, i just listed things i would change personally.

Maybe even your own thread would see more action as people dont really look at this one anymore.

Wow, thanks for all the feedback. rollitup wouldnt let me post something bigger. but I think your absolutley right about the flower filter and the veg chamber. I think I will make necessary adjustment to the design tonight. I was hoping that by not running exhaust tube directly out of the box that I would eliminate noise. I would like as quiet as possible. I will be Sogging so all the plants will be lollipoped and kept smaller. Ive done more with my current setup but the buds get airy. This will be a smaller compartment so I might just do 9 but testing will tell I tried to keep enough height in the cabinet as I do grow fewer/bigger plants once in a while. I have been running a closet for almost 3 harvests now but just want something modular that can move around with me. I invested almost 300$ in the project today but I know that the payoff is worth it by not having to pay for my supply. Thanks again!
