UV is 100% absolutely and unequivocally pointless.
https://uv-light.co.uk/uv-dosage-required-to-kill-microorganisms/

Even if you could achieve a log 6 reduction in your SAB, it wouldn't last longer than a few moments. The SAB is essentially an open air environment once its been disturbed, which would reverse all sanitization efforts almost immediately.
I watched YouTube video which outlined the sanitization SOPs for a large cordyceps farm in the US. They built a UV closet to "sterilize" empty tubs in preparation for spawning. They removed the totes from the UV tent, in open air, only to wipe them all down with ISO soaked rags on a bench...in the open air. 100% pointless.
Thats about all the time I have left to contribute to that topic.

To be honest at one point in time I thought, well it wouldn’t hurt!? With some help from this site and little bit of research I’m glad I didn’t.
Guess I could just put a led light in there and get the same effects. I’d never make fun of someone.

Listen man, I was making fun of you a page and a half ago.

But seriously, we're just here to help you succeed and I don't know if you've picked up on it yet but UV is a waste of time.
An SAB is stupid simple and 100% effective.

It’s a lot of misinformation, a touch of trolling and a dash of sarcasm; all woven into a group of tightknit mother fuckers That can’t decided whether to get along or just fuck with one another all day.
I’ll go back to my clean room and rock a G2G in my SAB. No UV and, absolutely, NO Moving Air.

This device says it's a laminar flow hood,but I am suspicious that it is actually a turbulence box,does the design of this look appropriate for laminar flow?(Hopefully this doesn't get me banned)

https://rb.gy/4pudl
If anyone else reading this wants to answer me please let me know if you think this type of flow hood is actually sound.

Basically the question I have for this board is if the filter is a 3" thick 99.9% efficient hepa filter & the fan is powerful & is pointed towards the back of the box floor(its top rear mounted fan) does this make it horizontal laminar flow or does the box have to have special ductwork to make it laminar flow?(assuming it has proper seal of course)

As far as I can tell these pics are how the fan box assembly looks inside,it seems to have a baffle that blocks direct airflow from hitting the filter directly. Can someone chime in on if this is what makes laminar flow & what other horizontal flow hoods need to implement to become true laminar flow?

Seems awful small and expensive. Pretty sure you can get a decent sized FFU for that price.
Vertical flow is quite a bit different to work with as well

Its 2'x2' filter area. Most hoods I've seen everywhere cost more for far less space than 370$ with free shipping. What do you think about whether it's true laminar flow? Any insight asap would be greatly appreciated

You're missing the point.
Fan filter units are cheap.
