I use a ghetto boxfan "flow hood" and I have great results using it for agar and grain transfers. So, while it is not ideal, there is a way to use that one successfully

It is quite an aasumption to say I have shortcomings in my "contraption" when you have no idea how it is designed and constructed, or that there's gaps in my knowledge, as you know nothing of of my knowledge or experience. And if it is really not up for debate, as you say, then there would be some legitimate peer reviewed studies on the effectiveness of Box fan flow hoods. If not then it is definitely still up for debate

I've used a SAB with a lot less stellar results 🤷

I'm not but hurt at all. I am just commenting for the people that are wondering are on the fence if they can do it for less money or not. And for clarity,I would guess it's more in between a positive pressure box/boxfan flowhood. And I didn't use cardboard. And for the people wondering, ignore the haters and elitists and just know that you actually can construct a decent flowhood with a boxfan. I have gone through around 250lbs of grain transfers using this with less than 1%contam rates. Don't let people discourage you from cheap diy stuff if it works efficiently

Tell me about it, and I have a 9-5 as well,I'm tired lol. And for what it's worth that 250 pounds was used in a very short time just since I made the flow hood. I've gone through thousands of pounds with a still air Box Also, I don't own an instant. I use a PC and, I use the worst, according to the shroomery😄, grain possible.....Popcorn Opening myself up to more hate there haha
And to be clear I'm not saying using an expensive laminar flowhood is elitist. I'm saying that people shooting other people down and calling them hacks or to be banned for using DIY methods is elitist

It may not be as efficient as an expensive setup but less than 1% contamination rate is very good for any grower.
And for you people who are not yet able to afford an expensive setup, just know that there are other ways you can do it efficiently. And you say to keep it on topic, well the 1st words of your post are literally Box fan flow hood so I think that this is right on topic

Those 2 merv filters cost just as much or more than my SAB, and I over-engineered my SAB. So far, I'm running 0% contamination using my SAB, so how is turbulent air going to be better?
Congratulations on having 0% contam rate with your still air Box. I'm very proud of you! Not everyone does though, and there are other ways to do things efficiently

This is not a supported claim.
I have no idea who you are, I cannot confirm nor deny the veracity of the claim, I cannot confirm your ability to identify contamination, I cannot confirm that the pictures are yours or if they were actualy grown out using the equipment that you've mentioned.
That's really funny, and to be honest I don't really care if you believe me or not. I am not commenting for you or others that are unwilling to accept different methods. Therefore I am not going to sit here and waste my time trying to convince close-minded people that are just going to be hateful and call for me to be banned. No, I am commenting for the people that may be lurking and possibly discouraged to not grow mushrooms because they thin they can't afford all of the fancy equipment. To those people, again, you can do it very cheaply AND efficiently. Don't be discouraged And yes the pics are mine, and yes I used the ghetto ass piece of shit flow hood for it lol

There is no way you can say it's a turbulent airbox without actually seeing the design and how it flows
And I never told anyone to do one thing instead of another. I'm just saying what worked for me and that it can't work for other people

Dangit, you know how to manipulate someone into continuing to argue even when they said they were giving up.
Please don't misrepresent what I say again so I can actually give up this time.
Ok same point but replace "box" with "contraption". There is no way you could know how the air is flowing in my contraption

ruawakeyet said: Laminar flow without HEPA level filtration still does not equal a suitable alternative, even if you did have laminar flow.
I'll give you this much, you might not have a turbulent air contraption. If a box fan is what is powering it, you likely have no air flow at all. Merv 14 filters aren't even recommended for HVAC units, because it's too restrictive and will burn up the fan motor.
Even if it managed to push a little air through it, it won't be enough to work as a flowhood, and the filtering capacity just isn't going to cut it.
According to the EPA merv ratings, these are not even close to a HEPA filter, which captures 99.97% or above, clear down to 0.3 microns. Look at these merv ratings:
merv 13: 0.30-1.0 less than or equal to 50% 1.0-3.0 less than or equal to 85% 3.0-10.0 less than or equal to 90%
merv 14: 0.30-1.0 less than or equal to 75% 1.0-3.0 less than or equal to 90% 3.0-10.0 less than or equal to 95%
It defintely moves air, too much in fact so that I have to turn it down from full power.

Thanks for your contribution.
I already said that I'm not here to explain it to people like you. Especially when you will just accuse me of lying, like you already have

ruawakeyet said: When I asked him if he has performed any open-air inoculations to compare against his device, I guess he was already performing open-air inoculations! There's no way he's getting any kind of FLOW from a box fan trying to push through 2 merv filters.
Thank you for your efforts to thwart such nonsense! You know how to actually help new growers.
Hey liquid, either you don't realize how badly you are potentially setting back new growers with this nonsense, or you're doing it intentionally. With your claim you are getting TOO MUCH airflow, and how you skipped over the fact that your filters are letting at least 25% of airborne particles pass right through, I'm leaning towards intentional.
It's moving enough air to easily blow a lighter flame out and severely affect a butane torch flame, so it is definitely flowing. Kind of ignorant to assume otherwise when you haven't even seen the contraption
And if by setting back growers you mean getting less than one out of a 100 jars going bad and 0 tubs going bad then I guess, yeah, I'm setting people back lol.

ruawakeyet said: Please shut us all up then. Show us this wonderful mervhood and a bunch of clean cultures on agar. Show us the laminar flow. The fact that it's blowing out your lighter is probably the turbulence, not the amount of air-flow. People using real laminar flowhoods don't run them fast enough to blow out a lighter, it should only bend the flame.
I'm tired of assuming when I haven't even seen it, so it's show and tell time!
Yeah, thats why I said I turn the power down lol. So it doesn't blow out the flame. Are you sure you can read well? And I am not gonna show pics of my "contraption" when you will just spew more hate and vitriol and call for me to be banned some more. I would be glad to show you plenty of clean agar culture that was made in my contraption, I can snap some pics when I get home from work

I know a lot of things have evolved over years. I have changed things over the years as well. However the boxfan flowhood is not something I've been using for a long time. I only adopted this method in the past couple months, so it's not about sticking to old methods for me. I'm open to all sorts new ideas and techniques
I was actually quite a bit resistant to it at first, but when I saw my friend running it with no issues I thought I'd give it a try
