your thoughts or suggestions on my laminar flow hood project

here is where i am with it. made out of aluminum. behind the alumninum looking blinds is gonna be a 120 volt uv light made for a whole house. in front is going to be a 2x2 HEPA. obviously blower in the back chambered into the uv light then through the HEPA. any ideas or scrutiny from anvanced cultivators is appreciated because i won't finish it till monday. thanks guys, it's my first time building a flow hood so my feelings won't be hurt if you see a design flaw lol.

As long as it's sealed up properly it should work. There is no reason to put a uv light in the plenum. It's doubtful it could do any good with the air flowing that much anyway, but it's not needed with a laminar flow hood. RR

UV-C lights can be very helpful in flowhoods, though not for sterilizing the air, but for surface sterilization of the work area, when it's not in use. it's often used in laminar flow cabinets, used for tissue culture.

when used in this manner, there must be protection, like in this picture, a glass window (which all laminar flow cabinets provide). normal glass filters out most uv-c light. though one should still leave the room as long as the light is on, just to be sure.
surface sterilization with uv-c is pretty effective, and there isn't very long exposure time needed.

well that suckss RR! the point of the blinds is to keep the light out completely. i don't want to see a spec of light coming through or else i might call off the whole uv part. also the blinds are going to left, right,center to kind of beat down any microns DNA before passing through the flow hood.
i kind of figured the uv light was overkill, but seeing i spent 142$ on it and included it in my design i may as well include it. i matched a filter to a blower according to stamets spec in his book, did you guys have to adjust your blower speeds at all to get them just right? i'm kind of expecting to have to because of the blinds design. i'll make sure to post the finished product,failure or not. thanks guys.

one thing i forgot: uv light can degrade a lot of materials. i guess you don't want concentrated uv-c to shine on your filter for a longer period of time.

aaaaarggggggg! i might have made the wrong decision with this whole uv thing. i'm gonna give it a lot of thought and make a decision monday wether or not to include it. thank's fruitbuddy.

We've known for years that UV has no place in mycology. You're not re-inventing the wheel, but rather using a square wheel that has already been disproved. I own a commercial mushroom farm and know and deal with dozens of others in the business and not a single one of them uses UV. Disregard bad advice from other noobs pretending to know what actual mycology labs do and use. RR

since there's no decision to think about i have a new plan. keep it simple, and go with what works. since i didn't weld the blind design, i'm scrapping it along with the uv light which i'll be taking back to get my 142 dollars back. it will resemble any normal flow hood. i'm gonna finish welding the aluminum today(which is a complete bitch!!) and get the hepa filter today. should have her air tight by the end of the day.
although i feel like a bit of a bone head after consulting with you guys about the whole uv light idea i'm very glad i did before i built this puppy to completion. thanks again and i'll post updates as i continue my build. here's the link of the grower that gave me the idea of the uv light, he really is a great cultivator, but he was obviously wrong here. and i wouldn't be surprised to find out he got cancer because he built a window for the uv light and you can clearly see light coming through his filter in one of his pics!!!!!http://www.shroomery.org/forums/showflat.php/Number/11120537#11120537

Using TIG?
Most guys use poly coated plywood since we often spray our labs with bleach solution. Bleach and metal, especially Aluminum don't do well together. RR

yes TIG. i've always cleaned my areas with iso alchohol. bleach and me don't do well together lol. hopefully alchohol will be sufficient enough because aluminum is what i got.

I looks cool and hell if your like me you must enjoy engineering things but this is way overkill... You could have had a sweet setup for low cost. I would fall back to a KISS guideline.

Can you elaborate on "poly coated" RR? Thanks as always.

so home depot fucked me. an order i thought to be getting yesterday isn't supposed to be here till mid fucking march! aaaarrrrggggg. 2 hours of talking to idiots about a simple order just to cancel it. the good news is i ordered a way better quality filter. here's a link where i am purchasing from. the specs are 18x18x5-7/8 99.99 HEPA metal frame. i would have ordered from perfecti but i have to have an 18x18 because that's what i built my project for. fucking home depot. let me know what you guys think of the filter. gonna take 20 days to get here so i'm bummed

You can also use lysol multi purpose disinfectant cleaner as a sanitizer. I don't use bleach in my lab because it can cause fruitbody abnormalities and it stinks like shit . It is ok to use in grow rooms as long as you clear and rinse the room before using. I use alcohol only to flash my needles and scalpels in front of the hood and i use a covered container for that. Another sanitizer is chlorhexidine available through vet supply online. I switch between the two.

What did you order from Home Depot?
If you ordered a 99.99% filter from Fitera B2B you are fine. They make awesome filters and mine arrived in 1/2 the time they quoted.

here's the one i ordered from depot. i canceled the order thank god, filter seems awesome.glad to here it took half the time they told you because they told me 20 days. also did they question you what you were gonna do with it? they did to me, not that i cared when the chick asked i said i'm building a laminar flow hood lol.http://www.homedepot.com/h_d1/N-5yc1v/R-203051809/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=hepa+filter&storeId=10051
i think this filter doesn't hold a candle to the filtera one so it worked out.just a bit of a headache in the process

You did exactly the right thing. That filter from depot is not intended for laminar flow, notice there are no aluminum pleats.
The reason for the questions from Filtera is due to numskulls buying them and putting them in standard furnace systems. They are kinda asking for your protection, not to be nosy.

i got my 18x18x5-7/8 metal frame hepa today. it's very nice, i'm glad i waited.

RR, do you think it would be ok to use this smaller HEPA 18x18 version as the pre-filter for the back where the fan sucks air in?

i got my money back for it but they still sent it. now i'm just wondering if i can use it or not. don't see any reason why it shouldn't work but since i won't start back on my build till monday i figured i'd ask. obviously it's overkill but i got it for free so why not?
