It was super epic the way you lit that burner! I don't know why that stood out to me so much but it looked like it was from like an action movie.
Lots of practice. 😀 Thanks for noticing!
Pro moves I think!
Fascinating. I've never seen that before.
Oh awesome here’s what I’m trying to do! I just have to get some bottles!
amazing video!
Great video!
Love the content! 🙏🙂
Wow ..awsome 👌 video
Great! keep em coming!
Thanks Ed, love you 😁
digging your videos man, good stuff! I try to comment on all of them for the algorithm, to help get them in front of more 👀
this video is gold :) Thank you. now I'm your psycho fan...
all that "auger", Youre killin me smalls 🤣
My British friend looks at me like I'm speaking a different language every time I say basil, yogurt, potato and tomato. You should hear Russians and Chinese pronounce Hygrocybe and Cortinarius. Bigger fish to fry than pronunciation differences.
Hi! I wanted to rewatch your tutorial on long term storage and was pleasantly surprised to find you've got multiple videos on the subject! Thanks again for all the useful info. I followed your tutorial a few months ago, and was wondering if you've got a recommendation for how long I should wait to test the samples for viability so I know I didn't screw up the whole lot.
I also noticed that you said the goal is to create an anerobic environment inside the jar so was wondering if filling the jar with more water would help to achieve this? With more water the samples would also float closer to the opening and (I suspect) it might be easier to retrieve them without contaminating the jar. Would you recommend using more water?
Incidentally, I have a few old LC jars that I haven't touched in months that have a thick layer of mycelium floating on the liquid. Could jars like these be considered similar to water vials? There is plenty of liquid in the jars and I suspect the water has little of the original sugars left.
Finally, what would you say longest a water-stored sample could remain viable? Thanks again for all your help!
You could do a voiceover in order to film while the flow hood is on.
bro...what we like on Edward is because we feel like we are on his room, he's our friend
This might b a dumb question sry in advance lol. I use blue food coloring an it changed the water in vile bule is that a problem. Ps. Thank you for all the information love your vids
Not a problem.
Do you think a spore syringe would survive after a half decade? I’ve heard spores germinate in the syringe, that would be almost the same thing minus agar nutrients?
Not sure. Spore prints last a long time. When they're wet though, I would use them ASAP. The mycelium is thick-walled and probably much more resilient in storage.
I’ve had syringes last 5+ years at room temperature. Ymmv
Not sure if you mentioned it…is it recommended to put the culture to water agar and then to the sterile water agar? Or would it be better to use put an agar slice with a little nutrition in it?
I just put it in as is. The level of nutrition in the sliver of agar is so low, once it leaches out, it shouldn't have an effect.
That seems like a simple method to do. Thanks.
I did have a question. Like when we AI heifers on the farm we just have a select sires guy show up which his tank carrying semen we’ve bought and he can store that stuff for years. Do mushroom farmers ever store mushrooms long term in a tank of liquid nitrogen I believe it is. It’s kind of late or way early. Ya cause some bull semen I remember reading have been kept for decades. If mushrooms degrade over time after many propagations you’d think growers would be like storing cultures frozen in a tank so they’d really last.
There are several ways to store mushroom genetics long term. Spores are the easiest.
Yes, people do use cryogenic storage for mushroom cultures.
Hi Edward, very live and educational video. Since you have a science background, how about glycerol stock of spores rather than water and keeping in regular freezer? This is just as a backup for purchased culture and for selective breeding (taking the biggest mushroom and saving its genetics). Like you, I have sterile bench experience, and I would hate to buy again a culture that I bought in the past and lost it due to contamination, drying out or flooded by condensation, labels coming off when spraying alcohol :), etc... My OCDs whisper to have a backup parachute... A dormant frozen glycerin stock was golden standard in bacterial cultures not sure fungi are the same. Like subscribed, thanks for sharing effective tricks that are not kicking science in the nuts. Cheers from Canada.
Spore prints and swabs are an easier and cheaper way to store mushroom spores. I have another video about the storage of live cultures.

I have been curious about super long-term storage with glycerol and DMSO. I used to store mammalian cells in glycerol/DMSO in liquid nitrogen and they basically were good forever (as long as the Liquid N2 didn't evaporate). I don't remember what the concentrations were and I'm not sure if live mycelium would handle this treatment.
Will this work for any agar plate mushroom for long term storage? Great videos
Yes.
is it possible to use sealed plastic water bottles? like ones sold in the stores
Yes. If you can sterilize them. They need to be PP5 or similar.

What's that wrap you're using? Is it better than parafilm and cheaper? Can you please let me know what it's called or where I can buy it from? Thank you in advance 😊
It just food wrap. Can buy at any store. I've got another vid cutting it. Way better and cheaper than Para.
@@edwardgrand Thanks bro really appreciate you 🙏
How many time one of those last viable?
Some say 10 years or more.
@@edwardgrand wow.. Just letting in room temperature. Wouldn't agar nutrients dissolve in that water?
@paulofx408 yes. But it is such a negligible amount. I think they'll eat the nutrients before hibernating. I don't like the way mycelium looks on water agar. I feel uncomfortable putting horrible looking mycelium in long-term storage.
