How to grow mushrooms without a laminar flow hood - what I would do without a flow hood (SAB)

[@themyceliumnetwork]

I am a home hobbyist that uses a still air box & even open air when my fruiting blocks are too big to fit in the still air box. because isopropyl alcohol is getting harder to find these days or is just way over priced I have been using Lysol spray a lot of the time. when I inoculate my large fruiting blocks in the open air I go into my den, close the door and turn off my forced air heating system, spray the room with Lysol wait about 60 seconds spray again & than inoculate the fruiting blocks & heat seal the grow bags. it has worked well (my first four blocks got contaminated because I didn't spray the air with Lysol) I now have six other 5 to 7 pound fruiting blocks that are colonizing very well with zero contamination. Gary gave me the idea with his incessive cleaning recommendations & his info on the great importance of a sterile working environment while working with fungi. I have learned the hard way not to ignore Gary's instruction about working as clean as possible ! Thanks Gary, My 9 year old Daughter got to eat some of our first Lions Mane Mushrooms yesterday, they were delicious !!

[@LarsLarsen77]

You can also get hospital disinfectant by the gallon and put it in an electric spray bottle with a fine mist output. It's basically ultra-cheap lysol (same chemical in it)

[@adamlightfoot5897]

This dude is a lab genius. It's hard to watch due to the perfection. Cheers myco master.

[@jidun9478]

Thanks Gary, this is pretty much what I am doing. I place a towel down as the floor of the system and soak it pretty good with a mix of alcohol and dish soap, this makes a surfactant which captures spores dust etc when it touches the surface of the towel instead of just bouncing around. I place a piece of tinfoil on top of it in the center of the floor as a working area and also spray it with alcohol, so far I have made 3 (one lions mane expansion, one as a needle biopsy from store bought shiitake and pink oyster cloned to agar clamshell technique then liquid) from successful liquid cultures proofed and qc'd on the no pour agar method you mentioned. I also have 4 grainspawn bags 2 lions mane and 2 shiitake and 1 pink oyster lc direct to substrate in large pickle jar with gas exchange holes in lid. All have been successful with no contamination so far! 🙂 Still growing out about to begin to go to substrate today with the grainspawn. It's really fun and thanks for sharing, I really like your channel keep up the good work! 🙂

[@TheRussianGenius]

Thank you, spray bottle idea is a gem with the isopropyl alcohol. Growing these things can be tough simply cause how easy contamination occurs

[@benlarsen1446]

Thank you so much!! My first attempt at inoculation with bought sterile bags ended up with cobweb mold and no mushrooms. I’m going to try again now with a SAB and I’m so much more confident that I will succeed this time! Thanks again!

[@chicofromph33nix64]

You my friend are the first person I have seen in these videos that knows how to pronounce agar. My father was a micro biologist so I am very familiar with it.

[@GSFaeFae]

I'm just getting into growing mushrooms (my first oysters are coming in today, I think), so this is great info. Went out shopping a couple of times yesterday to try to make sure I had everything I needed, lol. Thanks!

[@ORGANICPANIC]

Amazing info!! Cant tell you how much I appreciate your insight and carefully explained procedures 🙏🏼🔥💪🏼

[@paulbax8825]

For better visibility, I use stretched film instead of a cover. At the bottom of the box, you need to put a towel soaked in soapy water. And also to irrigate the walls of the sab, so that the fallen particles could not rise. And also make a double bottom from the grid to minimize contact between surfaces. I made an inductive loop sterilizer so as not to pull my hands out of the sab. Buy the largest container you can find.

[@FreshfromtheFarmFungi]

thanks for the tips!

[@MosesMLam]

Hey Paul. 2 years later, but building my SAB. Been wondering about sizes. You say largest size. I can find a 200qt clear laundry box. Is there anything as "too large" for an SAB?

[@relicboxing]

​@@MosesMLamget a 80 quart

[@michaellangshaw1521]

I must’ve missed that the first time I watched this video. I never thought of inoculating the agar and once it’s grown out injecting my non inoculated liquid culture into the agar and suck it up to use back into the LC that just took it out of. The simplicity of that is genius. The only problem with that is how can I get my anger culture to an isolated culture without making any transfers and opening up the cover? I mean I guess you could do that and just watch how it grows out and it will tell you whether or not it’s been contaminated. God that is so awesome.

[@mikehancho1613]

I can tell you as a learning newbie that I have not had a lot of success without a flow hood even being extremely clean and careful. That being said if you use SAB stick to liquid culture and grain jars with injection port and you can do pretty good!

[@Larsonboogie1]

over my 4 years of growing I'll say this. Flow hoods are a must if you are working with big bulk bags and ESPECIALLY if you are doing G2G transfers with grow bags But after 2 years of using a SAB, I ditched it and now just do my myco work in open air with very similar if not better contam results. Obv I am still using a lot of iso and following other procedures, but the real key is turning off any fans and letting the dust settle in your room for a few hours before work. Vaccuming once a week helps too and never do work directly on the carpet as that is where the bacteria settles, have a clean desk you can spray every once in a while. I still wear gloves and a mask and all that, but basically just work at a desk minus a SAB and no flow hood. If I had a flow hood, it'd cut back the amount of iso I have to use quite a bit but thats about it. I plan on getting on eventually, but wanted to share that even without a SAB, with the proper conditions and practices you'll do fine (most recent grow only had one jar contam out of 60.. all open air agar or g2g)

[@h7opolo]

always great to see the technology being used as intended.

[@richardknowles9212]

I use a sab for grain to grain transfer. I put bakers parchment paper on a formica counter top with all surfaces sprayed with alcohol. I buy 6 oz of grain spawn (on sorghum) and turn it into 6-7 quarts of grain spawn on steam sterilized millet. I have never had a contamination issue. I make sure that everything is sprayed down and do everything without moving my hands out until everything is capped.

[@FreshfromtheFarmFungi]

this seems to be a great method for that scale 👍

[@Rippedmagician]

If you don't want to use a sab, people swear by the Gordo tech. They're building their own flow hoods for under 100 dollars and achieving laminar flow.

[@kodyfrost]

Thanks for the info Gary, I'm working out of a SAB currently so it's always good to have great info on it

[@FreshfromtheFarmFungi]

thanks for watching! I sometimes use these for cleaning up dirty plates and working with spores/spore prints - it still is helpful when you don’t want contams flying around 🙂❤️🍄

[@Man-EatingMushroom]

@@FreshfromtheFarmFungi hey man been watching for a little while now and love your stuff, definitely been very helpful! So I used an SAB and now GLOVEBOX, and I just took foam banding (I forget what it’s sold as, furniture floor protectant or something) and wrapped the lip of my tote so when the lid is latched down, it does create that seal. And then I totally soak that seal with Lysol or another bleach cleaner that stays wet the entire time I work in there!

Really informative. Thanks Especially with the no pour agar jar.

Cool, man I used to live in castle rock when I was a kid we had 10 acres on a hill out west past the train tracks!

[@douglashaner6802]

Would you be able to remove the air filter carefully and inject through that hole....spray the connector of the filter and reattach. Rather than opening the entire lid?

[@FreshfromtheFarmFungi]

yes and even better if you didn’t touch the opening at all - it might be hard to get a clear shot but it could work

[@Johnny_Benson]

you rock brother man. and you don't even need an instrument!

[@love2grow493]

Bunsen burner with a propane tank way better then a SAB. Only drawback is that it is hard to work with spawn bags but everything else is fair game.

[@anakyn2010]

I mitigate the problem of air displacement the best I can by setting my Still Air Box up above my oven and combining the SAB with "Oven TEK". Basically there's a wall of 250 degree air blasting upwards from the open oven between myself and the SAB. That way I have to pass through that flow before entering the box. It has two great PROS and at least one glaring CON. The PROS are that, as already mentioned, it helps mitigate that air displacement into the box BUT it also helps to dry my gloves and arms faster after wiping them well with ISO which is a huge plus. It means as soon my hands are in the box, I can start working... which brings me to the CON - it can get hot af standing in front of a cracked open 250 degree oven. With the Oven Tek only, you are working on a grate above the flow but with the SAB combo you are basically standing in the hot flow. LUCKILY - mycology work is all about being fast and efficient and that hot flow is a great motivator LOL!

[@anakyn2010]

Also - my arm holes are only 4 .5 inches which is plenty big enough to do any of the work I do in there. 6 inches is pretty overkill. I've heard people complain about scratching or cutting their arms on the holes... my arms barely ever touch the edges but it wouldn't matter because they are very smooth. If you can afford the hole saw, you can afford a cheap pack of sand paper to clean that edge up. Takes like an extra 5 minutes tops.

[@hjm9586]

Hi Gary, thank you again for your help. I can't afford a flow hood, can you make an opening on the other side of the SAB and attach an Air Purifier pushing air towards you?

[@RayMigwans]

Awsome informative videos you make I'm a loyal subscriber. I a few have questions. Can a UV light be added? Would it help and? Or would UV light be damaging to mycelium.

[@themyceliumnetwork]

UVC lighting is great but not for your skin or eyes, so you can use it but not when you are in front of or under the lights unless you are fully suited up & are wearing UVC block glasses (which will make it hard for you to see your finer work)

yes it can help to pre-sterilize the workspace, just be safe about it to not get hurt from skin or eye exposure - bleach works just as well as a pre-sterilant just wipe it off after it dries with isopropyl and that is my favorite method.

[@dannyschumaker]

shouldn't u have flamed the needle before ur second draw?

[@ZeginMakesMusic]

I've been using a small alcohol burner inside of my still air box. I'm never in there long enough to start a fire and I always wait until the alcohol evaporates. Is there any reason why I shouldn't do this? Do tiny microplastics dissolve from the top? I'm only a week in and can't really see any contamination on anything. I've been trying to clone mushrooms from the grocery store onto plates. So far so good.

[@FreshfromtheFarmFungi]

yes this can work but I avoid open flames because of the fire risk. It just takes one bad accident to cause damage but if you are careful it can work - this is how microbiologists worked before the modern innovations

[@caseyshearer9519]

For the glove box system you mentioned, I wonder if adding a flexible membrane on the side of the box to act as an air receiver/bladder might not reduce the issue of air infiltration. Cutting a third hole in the side of the box, attaching something like a grow bag to it (as long as it would have at least the same volume as the gloves you are using have), and then making sure the box air pressure is balanced when in use (the bag is not over inflated when your hands are in the gloves, and not under inflated when your hands are out of the gloves) might be a good way of doing it. The bag would probably have to be cleaned pretty thoroughly though, as it would probably be a likely source of contamination if it isnt. Something like that might be more work than it's worth compared to a normal SAB like in the video though lol. Thanks for the video. Your content is very informative.

[@ChondroMan]

Just use a plastic tote that has a seal around the lid. That would almost eliminate the vacuum effect when moving around inside with the gloves.

[@wtfisthiscrap]

I was thinking of putting a HEPA filter on the box somewhere so even if it lets air in, it would do it through the filter so no contam. I may try something like that soon using cheap filters.

[@InfiniteVoid1]

What are your thoughts about working under a flame (or torch, I don't know the english term)? Like if I'm in a closed room, everything is clean with iso, would you consider that technic?

[@FreshfromtheFarmFungi]

yes that’s the old school method prior to flow hoods people would use the convection that’s created from a flame to protect the sample

[@InfiniteVoid1]

@@FreshfromtheFarmFungi okidoki! We still use this technic in biology at university since there's not enough room for all students to use only flow hood. But since it's in a real lab, it's clearly cleaner than in an appartement. Even if it's in an appartement, do you think it's okay with a flame or I should use a SAB?

[@quentin-g]

Thanks Gary, what would be your procedure to sterilise a syringe to reuse it over and over?

[@quentin-g]

@@FreshfromtheFarmFungi Thank you. I didn't know about the sterilization pouch. I begun to sterilize my plastic syringe in jars. They resist to heat but I had some contamination I didn't had before, so I think my procedure wasn't ok. I think it would be interesting to make a video about that ;)

[@mcscronson]

Found bleach to be more effective for spraying the inside of the SAB and soaking the bottom surface (I use a towel). Alcohol dries up too quickly to catch any floating particulates inside. Had most success that way, and with a mask.

[@FreshfromtheFarmFungi]

this can work well yes - bleach will leave residue so that is a down side but I agree it is effective

[@MosesMLam]

@@FreshfromtheFarmFungi Got it! I ended up using a soup can as it's the same size as the 4" coffee. But I may expand it to 5" and found some great tutorials on adapting a soldering iron to hold an exacto blade to cut through plastic. Also, I saved the 4" SAB cutout as it's 1. clear and 2. PP5 and cut it to fit inside the ring of my wide mouth mason jar - which gives me a clear lid for no pour agar! :) If it withstands PC (which it should), I now have a clear glass re-usable agar 'no-pour' container!

What if yoh made a SAB but cut a third hole at the back and attached a fan and hepa filter, so it blows sterile air into the box constantly? Like a flow hood but a flow box I guess?

caring for a clean workspace and considering all air movements is better than handling any still air box. I never had issues in open air condition not even in a living room.

[@FreshfromtheFarmFungi]

in nature there is a healthy biome of competing organisms and natural ecological niches and microclimates that allow for mushrooms to thrive. When cultivating them however, the mushrooms need to be isolated and kept sterile because other organisms will out compete the mushrooms and take over the substrates much faster like bacteria or yeast. In nature these organisms are controlled by checks and balances so to say but in vitro they expand rapidly too fast for the mushrooms to compete. Hope that makes sense!

Would it help (improve it) to use 80% isopropyl alcohol with 0.5% chlorhexidine mixed in? I was recommended it by my healthcare provider for the chlorhexidine's long lasting disinfecting capabilities for my skin before injecting the infusion set for my insulin pump. Also, might it help to put a UV-C lamp inside the still air box (if you wear eye and skin protection) to kill airborn mold and bacteria before opening any sterile containers? You could turn it on and off while working, for example if you have to take your hands out of the box and put them back in. Philips has made a small tabletop lamp that would fit inside a box like this. For me, it would seem like a good compromise for the lack of a laminar flow hood. :)
