Man I'd love the 2x4, thanks for the unboxing, it definitely sounds like one of the quietest ones I've heard. Do you think that could be due to that blower being internal and having more support/streamline path through to the filters, as opposed to the blower having 4 to 6 screws for support and having to fill a chamber to build enough pressure to blow out?
I wonder if mounting this on a narrow shelf and just a touch below the height of your table would offer two advantages- full use of table surface and no dead spot at lowest height on table.
Do you have to make a hole in the wall for the pre-filter to suck in the air to the room or just the pre Filter takes the inside air from the room and Filter it?
Any reason you got a 3 foot high one? I mean I've always understood the advantages of 2 high was primarily for bag work, I cant think of any benefits of it being higher?? Also got 4 cultures from you on etsy and transfered them all to 25 new dishes and so far they're looking great! Thanks. Will hopefully be at the farmers markets in a few months
Awesome! I mainly got the larger one because I plan on running it on low so the extra foot of laminar flow should help to offset the slow speed. I will be doing a more thorough investigation of the limits in the near future 👍 Glad they are growing out! Goodluck and MUSHLOVE
hi Gary, thank you for the video! Do you think you can make a video in regards to the efficient use of the flow hood and a maximum number of bags to inoculate in front of it?
Not that its not a great unit , but a couple of thoughts . 1. The same unit is now $1600 plus shipping 2. Im no airflow dynamics expert , but it seems like having a dead spot in the middle of the air column would interfere with laminar flow , also seems like it would defeat the advantage of having such a large unit . 3.the envirco unit of the same size ( and about the same price), uses a single filter with no divider , just sayin
thanks for issuing these concerns - the prices are always changing so I think if you could get a better seal than definitely go for it! (the freight shipping tends to be pricey for these) 2. The main reason I liked the two filter over the one is that the replacements for the two smaller filters is much cheaper than the big ones (almost 2k for a single filter compared to 500-600$ for the smaller ones) this will add up over the course of the lifetime - the bar in the middle doesn’t effect the work because I use this for inoculating bulk subs and the opening is above the line or I use it for tubs and other large inoculations which isn’t and issue 👍 I have a better air science lab hood for my delicate culture work although Ive used this for 6 months before while we were moving and had no issues
Super! Please tell me what class of filter is in this hood. h14 or U ? and how often do I need to change the filter? Are you satisfied with the laminar flow?
I would stand that in the corner of my table, add 2 foam strips to the bottom so it can't draft contam, so I could slide the pre filter towards me, 4ft up,...as the filter gets dirty, you won't have any dead spot in the middle. You have a clean air curtain around it now. Nice. Me likey..me wanted.. lol
It’s not ideal but you can sterilize it with alcohol and a UV light but I just ran it for a few hours after setting up and it was fine - a better way would be wearing gloves
What is the main difference with this versus a flow hood with like sides etc? I mainly grow mushrooms for friends and family but i have been debating trying on a local market but i think having better equipment helps a bit. I was looking at a laminar flow hood but they take alot of room and this will work similar?(perhaps not as good butt good enough) do you just turn it on ans start working or let it be on for a bit before use?
I had the same one, and you can turn it on and go. But if you have it in a small room you mAy wanna run it for a bit just to clear up any floating contam around the room for a bit but you don’t have too.
you should definitely turn it on for a bit before working in the room (unless you have a legit clean room, then no need). Most of us dont have that luxury, as we work out of out homes (for instance I do my work on the dining room table). Always run the FFU for a bit before you work, to allow this device to clean the air in the room, not just in front of your workspace.
I got it from a restaurant supply store - I also have 4 more at my other lab in Denver. Got some great deals off craigslist before - one came with a stainless steel prep sink for under $100 and is my favorite to date : ) probably an abundance out there because of all the restaurants closing and liquidating
I'm considering one myself but I'm reading alot of things saying that the diy style flow hood/cabinet is better. They seem to do the same thing in theory but I'm no expert.
that depends on your level of handy work - personally I would not scrimp on a tool like a flow hood it will give you frustrations if it’s not built correctly but that’s not saying it can’t be done 👍🍄❤️
@@FreshfromtheFarmFungi I think I could build one but if an ffu is going to do the same job as well as save me the hassle of building one I see no reason not to go with it.
I think you summed it up well 👍 they will work in a pinch, but a true laminar flow requires proper air circulation and design. That being said, some of the best flow hoods still may have dead zones - just know the limits of the equipment that you are using 🙂
@@FreshfromtheFarmFungi it doesnt seem like 4' deep unless you mean height? im looking for one right now for my flow hood. theyre hard to find for a decent price. just looking on craigslist ebay amazon offerup etc with not much luck so far
No way you're from Castle Rock! Some of my family is from there. Technically I was employed in Castle Rock but we traveled for work. I'll be to Castle Rock in March.
in theory yes, but you need to work with the organisms in order to cultivate mushrooms and UV is also extremely harmful to skin/eyes and can be very dangerous. Many flow hoods come with a UV light on a timer to help clean the workspace prior to use but usually the technician leaves the room during this process
@@FreshfromtheFarmFungi I was wondering if I could use a small UVC bulb to do mutation breeding of mushroom cultures on petri dishes. If I get the timing right it will just mutate, not completely kill it.
Yup, it's not a laminar flow hood. The filter is too thin, the plenum is too small. These are actually designed to mount to the ceiling in a clean room pointed sideways. It's basically a fancy air purifier meant for chip fab facilities. They have one of these things every 10 feet or so on the ceiling.
@@LarsLarsen77 its not laminar flow, nor a hood. Thankfully he doesnt claim this FFU is laminar flow, but he still does call it a hood, which it is not. However, in this hobby you dont need laminar flow nor a hood. Even a makeshift BBFFU is sufficient for this hobby. Definitely wouldnt want to run a business with one, but a legit FFU would work out just fine, even for a business
I've been doing so much research, debating myself whether or not it's worth it... in the long run, maybe, but i don't think my contam rate is high enough to justify the price of a quality ffu. BTW, their website has only got a 2'x4' & it's $1,050 not including freight... some inflation, huh? Jesus christ...
@@WhiteBeardHashtag1205 I ended up building a big 24x24x6 w/ an inline fan, but the filter came badly ripped & I couldn't send it back, so I had to seal it with silicone. It worked for a while, but was unwieldy so I ended up building another one a few months ago that's 11x16x2". Much more manageable & well worth it since I use it so much.
I know that you have a ton of experience, so I am totally confused as to why you are calling this a flow hood... This is 100% not a hood, this is literally an FFU! This is a common misnomer in the community, people calling everything "laminar flow" and "hoods". I know you didnt claim this was laminar flow, and I appreciate that. However, you called this a hood, which it is not. You are a leader in this community, whether you want to be or not. You should be teaching these hobbyists proper terminology, not propagating falsities and incorrect terms.
