Hello Tony, can we get a short video or an update on the flow "hood" after two years of use? Thanks. Love the Content. Always a pleasure coming back to your content. Keep up the good work! 👍🏻
Nice job! Only point I'd make is a recommendation to stain and finish the wood with lacquer or polyeurathane of some kind. Raw open wood can hold all manner of contaminants. Love the channel!
Hey again, I asked for help about a year ago with agar. Today my mushroom farm is over a year old and brining in steady sales. Thank you for your help way back when! Clear Sight Farms
I bought a book on growing mushrooms about a year ago, and put it down dismissing mycology as to complicated. I started watching your videos and now things seem a little more simplified. Thank you for your content.
Well done guys! I'm sitting here watching this, drinking my morning coffee with a scoop of Thrive 6 mushroom powder. When all of the sudden I realize that this video is from the same company. Small World.
Nice job & thanks for making the plans free to those wanting a horizontal laminar flow hood. The only thing I think I may have done different is paint it with an anti mold paint/primer. At least on the inside. Probably sprayed on smooth so the porous wood didn't hold any dust. What was the total price to build it & how has it been working for you?
Many talk about how they built there flow hood but you showed step by step, I retired in 2017 and moved from Arkansas to iligan city philippines and i just received 24 x 24 inch hepa filter today and blower 3 days ago, building a flow hood and going to grow mushrooms here in philippines.
I've come not only to think, but know so!!! My mushrooms are my greatest advisors in life too. There is a fair exchange. I see the wisdom of fungi as a universal knowledge, which they figured out! Had to respond, as few people mention such thoughts! If there is one thing I truely believe, yes, I believe in mushrooms, and love them!
Nice build. I'm watching this because I am building something totally different - a fume extractor for a CNC laser, but it uses a lot of the same ideas. Also, just wanted to point out that silicon is a chemical element which is basically a hard, metal rock. Silicone is what you use for caulking =)
I know a little improvement that would help extend your filter life and efficiency at filtering out the bad stuff. Install a uv-c lamp that is usually installed in hvac systems. This will kill all the air once it passes the pre-filter on the top of the box that is built around the blower intake. Uvc helps to kill all germs, bacteria, and viruses.
I would guess based on how he made this that only half of the pre-filter every shows any sign of dirt. For better air entertainment I would have rotated the blower 90deg, with the intake facing the front wall, and put the pre-filter on the back. This will ensure that air is being pulled through the entire pre-filter, not just the area under it.
FreshCap Mushrooms quick question. What substrate would you recommend for a noob grower, straw, wood chips or grain? Can you even grow in grain? Sorry, one more. Do mushrooms only need carbs to grow, wouldn’t adding vitamins and minerals increase yields? Thank you kind sir ;)
Depends on what you have to treat the substrate and what species. If you can sterilize in a pressure cooker, I would suggest sawdust supplemented with bran, works for almost all gourmet and medicinal species. Or the "masters" mix which is 50-50 soy hulls and sawdust for anything other than shiitake. And for the nutrition requirement, it depends on species, but primarily sugars (bran) and lignin from the wood
You don't need to use birch, but it will paint nice. Cheaper alternatives would be either AC or BC sanded pine. The letters stand for the grade of wood used on each side. "A" has no knots, "B" may have some small knots with "football" plugs covering larger ones, "C" will have knots. Also when cutting birch or oak, the side facing up will splinter when cutting with a circular saw. The bottom side won't. It may also happen when using pine, but that depends on the blade you're using.
LMAO that mushroom shaped cord holder is the best. Btw, just binged watch your 18 videos from oldest to newest. Definitely learned a lot in the last few hours, so thanks a lot, mate!
Really nice build and great plans. Thank you so much. You asked for corrections so here's mine. There's a difference between silicon and silicone. two different words, two entirely different substances. Silicon is the element used to make transistors. Silicone is a polymer (that does contain some silicon) that is used as a sealant. You used the word silicon both in your speech and in the plans. Change both to silicone. The pronunciation is different also. thanks again.
So you're pulling the air through the filter? Then blowing that clean air into the box and through the directional aluminum face? Did I get that correctly? I'm building one with aluminum and Glass panels. Was going to have the filter last and not 1st like you have it. Not sure if that makes a difference or not 🤷♂️
That's awesome! Only thing I would change is to add a 10-15 micro farad capacitor to eliminate the wind up on the blower motor. The motor will start instantly and also last a lot longer.
Everything about this was great. Any possibility to cover more on wiring the chord and switch though? Seems no one can find that info across the board on all myc forums
I'm really glad I found your channel. I just want to say thank you for sharing this info and showing us the whole process; some of us need a visual to learn something new :) I now have what I need to start growing my Lions Mane and Reishi.
Technically speaking this is a "clean bench". A laminar flow hood provides downward flow to protect the operator from the medium/culture/bacteria. Kudos to your solid engineering skills and hepa selection. Industry standard hepa filters are rated "C" in america and "H14" in europe. Curios why you chose a 24 x 48" filter. Do you think a 12x12 would be sufficient for agar work and innoculations?
Nice job! Would there be any advantage to building to front frame out a little to make a sort of tunnel to work in, or is the flat face effective enough?
Hi Tony, thanks so much for this video! I copied your design and it works really well. The only issue I'm having is the hot air. Perhaps my space is a bit small and not properly ventilated but wanted to ask if you have any recommendations to avoid or improve on build to avoid the hot air generated from motor? Mine is blowing 32 degrees celcius air!
Hey could you please share how much space you have of table, in front of the flow hood, I mean, what’s the coverture area of the air flow. I’m building a table for mine but I don’t know how much space to leave for working area, and I want to take the most advantage of the converture area of air flow from my flow hood. I built exactly this one
Something I am running into that I thought I would share. I was lucky enough to score an autoclave. Seems like most people are using pressure cookers and wont have this problem but if you are running a lamina hoods it might be something they have an issue with and I am now curious about your setup in particular. My autoclave draws 14.5 amps and now I am looking into adding another breaker for it. I was just wondering what this fan draws and if you might of have the same problem? Probably not a problem for most but just something else to think about when getting into this adventure and you are trying to figure out costs.
So I'm building this now and the wiring diagram doesn't show the ground being used. Did you use the ground in the little grey box on the blower? In the build plans you said to ensure that its grounded properly... I'm not trying to hire an electrician lol. Thank you for this video and build plans!
Im following since first videos and I repeat : BEST mushroom channel for sure! Good vibes from México! Next year I will try my own flowhood, I just need a Hero Friend like him LOL
@@FreshCapMushrooms what if i wasnt able to do the carpentry and didnt have the space for a full box/hood to make a laminar flow hood, and decided to use a BOX FAN behind the HEPA FILTER and that's it. will that work???
I don't know how laboratory test the flow hood but I imagine some fog test and see if see if the air give a consistent flow. I imagine too much pressure or too little pressure will cause turbulent.
Great video! question, i'm getting ready to build one but i want it to be thinner/deep from front to back so it takes up less space on my table, how much less space can i leave? also is there a good way to give the blower different speeds so if it's too strong i can dial it down?
Hello Tony! Where can I buy the HEPA filter. I need 24"x48" double size Hepa filter and the blower Dayton brand, please give me the specs for the blower machine and the filter for the blower. Did you use Palo Tsina plywood for the frame?, could it withstand when the blower and hepa filter works together . What about the 5 wirings, what are these for? If you could give me where to buy those? Thank you very much. I will not skip ads to support you on your channel every time i watch it. I have already subscribe and hit likes button. God Bless you.
Awesome video! I’ve read plans on how to build a flow cabinet but watching you guys really helps a lot. Thanks! How are you going to replace the filter when needed?
Hello. Love your videos. Thinking about building this hood. Realizing how hard it is to find a 24x48 filter and when you do how expensive they are. Could i not take two 24x24 filters and silicone the center seam?
is there a specific reason why the overall cabinet is 20" deep? 6" thick HEPA filter + 6" wide blower = 12". Would a 16" deep cabinet be sufficient? 20" deep cabinet on a 24" deep stainless steel prep table seems like a bust. thanks in advance for your reply!!
Looks like a quality piece of work! Have you ever tested to see how even the flow of air is? E.g. to see if it is faster at the top than at the bottom. Could probably test it with a piece of thin paper.
Sorry it may be a stupid question, but do you pull air from inside the clean room and circulate it over and over thru the Hepa filter(hood) or do you pull air from outside, then the Hepa and into the lab? If it's from the outside how do you handle the outflow of air. (Is that how you achieve positive pressure?) Thank you in advance for your answer, And I apologize if its something you've covered and I missed..
Just by looking at it, I think it's just pulling air that is already in the room and circulating it. I think this would work fine for mycology work, but not for something more dangerous like virology. I don't think positive room pressure is a concern for what he intends to do with this hood.
Is this a 5 7/8" deep filter? How long did this filter last? I'm trying to build one, but I don't want to use the 11.5" deep model. Does the depth really affect the life of the filter that much?
nice video, appreciate the efforts u have put into Tony. i am trying to build one (24"x24") but not sure which material HEPA filter to buy (aluminum,steel or anything else that i might not be aware of) lightweight, provide the expected results and also not cost that much. Any suggestion...?
I have a doubt, sir... Schematics looks great! But I would like to set the blower unit outside with a prefilter hood and connect it with an air vent to the HEPA filter unit inside. My doubt is based on the length of the air vent would I need to calculate and buy an air blower...? Will, there be a pressure drop in the air passage...if so how to calculate it...? any suggestions will be helpful thank you!
Can you provide any explanation on why the design calls for a 2x3 to be used and not a smaller piece of wood that would obstruct airflow less to the filter? I also wondered at the orientation of the 2x3, and how the upper attached one doesn't have the 3" portion attached to the top like the bottom one. Is it vibration? Does the geometry increase airflow? Very curious. I am assuming that the...(6.18) is 6 and 1/8 in back from front of bottom wood portion. I have seen other construction methods that use 4 strips of long thing wood that butt up against filter and run to the rear panel.
@@FreshCapMushrooms I've watched a bunch of your videos and have learned a ton from you. Very clear and concise information. Top notch work. In both mushrooms and TH-cam videos.
I've seen some used Laminar Flow Hoods online that seem to be cheaper than buying all the materials to build this. Does anyone have any strong reservations about a used one? I love being hands on and this video and you alls plans are very detailed and helpful! Just want to be the most frugal and time conscious for a project I'm working on
Hi Tony? Thanks for sharing. I downloaded the full built plan and there are many info. Actually I am using a glovebox to do my orchids seedlings but am getting too many contaminations on my flasks. Planning to build a laminar flow hood to do my orchids seedlings and this will help. Bye, Daniel from France.
@@FreshCapMushrooms Thanks! I ended up finding a video of an actual science teacher showing how to use and operate and industrial size flow hood. His recomendation was to turn it on 15 mins prior. He also cleans the area while its on. th-cam.com/video/ORT01wl8vlY/w-d-xo.html
Awesome build. Right now I'm using a positive pressure glove box for my work, but I'm waiting for a 2' x 4' HEPA filter like yours that I'm building a blower for from scrap parts. Will definitely reference your videos during the build for the great info.
Is the request to get the plans emailed to us still viable? I usually prefer to make my own stuff and I really liked the simplistic and straightforward design for this!
Do you ever have to clean the back of the HEPA filter? Surely if it's doing its job, it'll end up blocked eventually, right? Or is it a matter of replacement at that point?
Really informative thanks Tony! Could you give me a rough idea of how much it cost for the materials? I’m just getting started growing and I’m tempted to save some dolla by building my own laminar flow, cheers :)
Hey man. I was curious, if using a 12" filter would the fan need to sit 12" back from the filter? Or just 12" back from the front of the box? Sorry for the rather stupid question!
Great video Tony. I subscribed in order to get the plans and ran into a problem with the link that arrived. In Firefox, the link begins to open tabs, one after the other, in the browser at rapid speed (was up to 99 tabs within 7 seconds before I closed the browser). This was a repeatable bug. I pasted the link into Chrome and the pdf file loaded without any problems. Thought I should let you know. While I'm at it, might as well let you know that video 1 would not play on my smart tv (Panasonic). Error message says something about an unrecognized format. Video 2 plans on the tv just fine. Thanks for the plans. cheers.
Thanks for the heads up! I will try and get that fixed, it downloads from mailchimp servers, so not sure if I can do much about it. I might switch providers... Glad you were able to access in Chrome! As for the first video, not sure, it's the same format as the second video.... Thanks for watching!
That's a pretty slick idea! You've already got power running to that space anyway and I can't imagine it would be hard to add the fixture. I wonder though, how long does something like UVC take to be effective at sterilizing? Also, would that in any way make it unsafe to sit in front of and use? I love these mycology channels because I see a lot of great comments with really good ideas to ponder.
Nice. Does anyone know a link to a video showing how much air is coming out? Like a flame or smoke test video? All the calculation videos I've seen don't give me any kind of idea what I'm looking to have acceptable flow coming out. What's too much, what's too little and useless. I'm thinking about using pvc to make a box I can walk into, covered pvc frame with painters plastic filter mounted to the pvc frame and a shop vac pulling air from the opposite side. Will I have enough flow in front of a small hepa filter? I'm just learning all this and have only been growing for 5 months. Did my 1st lc to agar in my kitchen in open air and had 4 out of 20 dishes grow something extra. If my idea will help me reduce to 0 out of 20 I'll do it but I'm wondering how much air you want blowing past you as your working on your projects?
I'm curious too. I just got materials fan, filters...will be building this week. Using 2 Merv 16 filters 20x25 side by side 6 inch thick. I bought a 12 dollar anemonitor? To check wind speed after filter. Thinking about making box 25 x 40 wide but slightly bigger to fit 24x48 if I need a HEPA later? What are your thoughts?
This is great! I love your content. I've been setting up a small lab space for yeast culturing for sake brewing. I'm also building an incubator for making koji (rice inoculated with aspergillus oryzae). I just realized that this is also pretty much the same equipment I need to grow mushrooms, so I was thinking I'd try to grow something easy like Lion's Mane. 1. When using a flow hood, do I need to worry about safety? E.g. if I try to grow mycelium on an agar plate and it's contaminated with something bad, do I have to worry about air blowing directly toward me? 2. In my yeast lab, I'm currently using an alcohol lamp. Brewing blogs say that this creates a small "sterile" field around the lamp because of the flame's updraft. Would this work for mushroom growing?
4:25 The joy on his face when things work out as planned. Nice job!
Hello Tony, can we get a short video or an update on the flow "hood" after two years of use? Thanks. Love the Content. Always a pleasure coming back to your content. Keep up the good work! 👍🏻
An update would be nice
I would also like one, I hear online fans ante now cheaper and just as effective
same
I just built one following this design! Will test later this week.
Did anyone ever do a anemometer test? If so what was the cfm reading? If not lighter test?
Nice job! Only point I'd make is a recommendation to stain and finish the wood with lacquer or polyeurathane of some kind. Raw open wood can hold all manner of contaminants.
Love the channel!
I was thinking the same. How about ptfe coating.
Yep! Epoxied mine
@@patmanpatmanson 100%, but the same could be said of the prefilter. Doing the extra work now will prolong the life of the $200+ filter
overkill
Good idea!

Hmmm did u calculate in the pressure loss from the pre filter? I suppose having an 100cfm over blower is good for that loss.
Is this working effectively??? Which is better laminor or this?

Very curious. I am assuming that the...(6.18) is 6 and 1/8 in back from front of bottom wood portion. I have seen other construction methods that use 4 strips of long thing wood that butt up against filter and run to the rear panel.
Do you have the information for the 24x24? Fan filter etc.?
You guys did a beautiful job on that. Well done
Thanks!!!
@@FreshCapMushrooms I've watched a bunch of your videos and have learned a ton from you. Very clear and concise information. Top notch work. In both mushrooms and TH-cam videos.
thanks for sharing, i was really looking for ideas to make my own laminar flow cabin
I've seen some used Laminar Flow Hoods online that seem to be cheaper than buying all the materials to build this. Does anyone have any strong reservations about a used one? I love being hands on and this video and you alls plans are very detailed and helpful! Just want to be the most frugal and time conscious for a project I'm working on
Please do a follow up with a finished version and demo. x
NICE. This channel is becoming invaluable.
Nice shroom, btw! Love the flair!
Haha thanks, that was Jeff's idea. Love the way it turned out.
Awesome vid my friend, hows it still working for you ?
Hi Tony?
Thanks for sharing.
I downloaded the full built plan and there are many info.
Actually I am using a glovebox to do my orchids seedlings but am getting too many contaminations on my flasks.
Planning to build a laminar flow hood to do my orchids seedlings and this will help.
Bye,
Daniel from France.
I hope this isn't a dumb question, but when do you turn it on? While you're working? Is it left on all the time? 30 mins before transfers?
Usually about 5 minutes before I'll turn it on, then work in the stream whenever you need sterile air 👍
@@FreshCapMushrooms Thanks! I ended up finding a video of an actual science teacher showing how to use and operate and industrial size flow hood. His recomendation was to turn it on 15 mins prior. He also cleans the area while its on. th-cam.com/video/ORT01wl8vlY/w-d-xo.html
@@marcmarc4776 Great link. Thanks! That actually sort of answers another question posted in the comments about adding a UV lamp to this build.
What type of filter is best for the pre filter? Should it be activated carbon or anything?
Sweet video man. Now all it needs is a nice seal job and flip the switch! Thanks for sharing bro!
Quick question :-
Wont there be fungus eating the wood?
Awesome build. Right now I'm using a positive pressure glove box for my work, but I'm waiting for a 2' x 4' HEPA filter like yours that I'm building a blower for from scrap parts. Will definitely reference your videos during the build for the great info.
Awesome! Thanks for watching
This build is so nice
Love your content, everything is so clean and crisp and to the point. Very useful stuff, thank you kindly
Is the request to get the plans emailed to us still viable? I usually prefer to make my own stuff and I really liked the simplistic and straightforward design for this!
Do you ever have to clean the back of the HEPA filter? Surely if it's doing its job, it'll end up blocked eventually, right? Or is it a matter of replacement at that point?
Very useful content my brother.. quick question can you please tell whats the name of the fan that you use for this box ?
Do you remember which size Carriage Bolt you used ? Any chance you have an example ? Thank you !
1000th like, great video! Love all of ya'lls stuff! Very informative and the most professional formatting (good taste in music too). :)
Very nice, I like the explanations from you and your friend both. Even the simple heads ups.
Really informative thanks Tony! Could you give me a rough idea of how much it cost for the materials? I’m just getting started growing and I’m tempted to save some dolla by building my own laminar flow, cheers :)
I'm building one right now, about 1000.
Hey man. I was curious, if using a 12" filter would the fan need to sit 12" back from the filter? Or just 12" back from the front of the box? Sorry for the rather stupid question!
The mushroom cord holder thooooo!! Love it bro nice build man 👍
Hi. Where I can purchase AstroCel Hepa filter, can you let me know please?
Great video Tony. I subscribed in order to get the plans and ran into a problem with the link that arrived. In Firefox, the link begins to open tabs, one after the other, in the browser at rapid speed (was up to 99 tabs within 7 seconds before I closed the browser). This was a repeatable bug. I pasted the link into Chrome and the pdf file loaded without any problems. Thought I should let you know.
While I'm at it, might as well let you know that video 1 would not play on my smart tv (Panasonic). Error message says something about an unrecognized format. Video 2 plans on the tv just fine.
Thanks for the plans. cheers.
Thanks for the heads up! I will try and get that fixed, it downloads from mailchimp servers, so not sure if I can do much about it. I might switch providers... Glad you were able to access in Chrome! As for the first video, not sure, it's the same format as the second video....
Thanks for watching!
Great design, and nice video, the theory part too, thanks for sharing. I like the way you use the rubber to make airtight connections.
Thanks! Glad you like the video!
Any idea where to buy the filter for this big now a days ?
Could you put a UV light chamber before the 2nd filter?
That's a pretty slick idea! You've already got power running to that space anyway and I can't imagine it would be hard to add the fixture. I wonder though, how long does something like UVC take to be effective at sterilizing? Also, would that in any way make it unsafe to sit in front of and use? I love these mycology channels because I see a lot of great comments with really good ideas to ponder.
I want to build a 24x36 but the blower closest to what I need is the same one you’re using, is it too much overkill to use this blower?
How often should you change the filter?
awesome video. I will try to build this
How often would the HEPA filter need to be changed? seems like an involved task with this design. Looks great otherwise
They can last up to 10 years if you are diligent in changing the pre filter when it needs to be changed
Thank U So Much Tony Bro..for making this video....it's very helpful for me.....Thank u once again🤗
Love from India🇮🇳❤
Where do you get the hepa filter and the rest of the stuff?
Nice.
Does anyone know a link to a video showing how much air is coming out?
Like a flame or smoke test video?
All the calculation videos I've seen don't give me any kind of idea what I'm looking to have acceptable flow coming out. What's too much, what's too little and useless.
I'm thinking about using pvc to make a box I can walk into, covered pvc frame with painters plastic filter mounted to the pvc frame and a shop vac pulling air from the opposite side. Will I have enough flow in front of a small hepa filter?
I'm just learning all this and have only been growing for 5 months. Did my 1st lc to agar in my kitchen in open air and had 4 out of 20 dishes grow something extra. If my idea will help me reduce to 0 out of 20 I'll do it but I'm wondering how much air you want blowing past you as your working on your projects?
I'm curious too. I just got materials fan, filters...will be building this week. Using 2 Merv 16 filters 20x25 side by side 6 inch thick. I bought a 12 dollar anemonitor? To check wind speed after filter. Thinking about making box 25 x 40 wide but slightly bigger to fit 24x48 if I need a HEPA later? What are your thoughts?
This is great! I love your content. I've been setting up a small lab space for yeast culturing for sake brewing. I'm also building an incubator for making koji (rice inoculated with aspergillus oryzae). I just realized that this is also pretty much the same equipment I need to grow mushrooms, so I was thinking I'd try to grow something easy like Lion's Mane.
1. When using a flow hood, do I need to worry about safety? E.g. if I try to grow mycelium on an agar plate and it's contaminated with something bad, do I have to worry about air blowing directly toward me?
2. In my yeast lab, I'm currently using an alcohol lamp. Brewing blogs say that this creates a small "sterile" field around the lamp because of the flame's updraft. Would this work for mushroom growing?
Tony i Enjoy all of your videos, Thank you.
Thanks to YOU for watching!
How did this bad boy perform??? good flow? looking to build this thing by myself :)
What was the approximate cost of this build? Thanks!
Can you provide a link to the fan?
In order to change the HEPA filter you'll have to remove the 1x strips to get it out correct? It's not easily removed like the pre-filter.
What do u mean?
If you keep up with changing the prefilter your hepa will last up to 10 years
