You should use both. They are both different from one another. Agar plates are a great tool to germinate the spores from the syringe and isolate individual strains from it. Agar plates are also useful for longer term storage of the mycelium.
What's your method for getting rid of all that condensation? That's my biggest problem yet with agar. Plates are flawless crystal clear, but by the time they've sat in the sab and cooled, nutrient plates all get spots. Any advise?
Great vid thanks. So condensation on the plates don’t matter? Isn’t it better to leave the plates in front of the hood without lids until they solidify ? Or would that increase chance of contamination? I have a flow hood so I was thinking of placing them right in front
Yeah you should cover the plates as soon as possible, you can store your plates upside down and the condensation will not fall on to the agar/mycelium.
Store them on a shelf at room temperature. Temperature fluctuation draws out moisture from the agar and causes it to dry up around 6 months. Keep at steady temperature for 6-12 months and transfer to new plate before it drys up.
You can put a heating pad on top of the dish to help get rid of the condensation. To make sure there is no condensation to begin with make sure to pour at 125 F. If you pour hotter than 125F there will be condensation.
Do you have a video or images of your flow hood? I saw the links below of what to buy but curious how you set it up? Also do you have a hammock filter on it as well?
Yes I have images but I can’t post them here, I’ve built a couple of them. You just build a box around the filter leaving space behind the filter and then attach the blower on top above that space. You can also build a box around the blower motor and add the pre-filter to that. If you want to email me at Sporensprout@gmail.com I can try to help if you run into problems.
Hey bro what’s the foil for inside the lining of the PC? I have the presto 16 and 23 quart so I’m curious if I’m missing something ? Also,is that parafilm or grafting tape that you used? I have a box of parafilm now but was using a roll of cling wrap (also gas exchangeable) and cut the roll into 1-2 inch pieces and worked with that. Micropore tape always leaves a residue on the dishes which can allow contams to stick easily. Mush love!
Sometimes my fruiting bags would melt if touching the sides, didn’t happen anymore after I lined it with tinfoil. Some people use wet towels, idk maybe I was pressure cooking higher than 15 psi on accident and that’s why it would melt when touching the sides. Either way, doesn’t hurt.
generation after generation of transfers, stabilizing techniques to get stronger colonizing and eventually fruits, will my isolated species ever show genetic markers from older lineage and parts of life the species fits in amongst?
In another video he added yeast to it too, i couldn't understand the logic behind it , since we don't want to culture yeast or any other organizm but mushroom on it, then why yeast, so i came to this one.
Yeah that will still work, Here is the updated video though: My Favorite Recipe for Making Agar Plates Full Tutorial ruclips.net/video/otBU3jlUZAE/видео.html
@@SporenSprout I wipe down the inside and outside of the hood with 91% alcohol before I do any bacterial inoculations on purchased pre-pours and get good results. I'm gonna try this protocol with your method...I'll let you know how it turns out.
How long can they keep without mycelium on them? Best to keep them in the fridge? I’ve bought a pack of twenty but I only need 2 currently. Guessing it’s best to do then all now and store them rather than bag them back up and chance contam?Thanks spore ✌🏻
They actually keep for quite a long time especially if there isn’t a lot of temp fluctuations drawing moisture out of the agar. Usually still good to use up to 6 months at room temp.
I've seen several people selling charcoal agar plates. Would be pretty cool to watch the mycelium grow against a black background. Do you think itd be safe to mix a little activated coconut charcoal into this recipe?
You can use nutrient agar by it’s self. The light malt extract is used for nutrients when using regular agar agar, which does not have nutrients and will not support healthy growth on its own.
Honestly you only need light malt extract and any type of agar. You would have to mess with the measurements but yes you can replace light malt extract with grain water, honey, potato water, or basically anything really.
I store them on a shelf at room temp while they grow and once they are mostly colonized I put them in a mini fridge. Usually good for 12 months or longer like that. If left at room temp they will start to dry up after 6 months.
First of all, mason jars pour like shit, and an empty liquor bottle is just whatever is around. How about you get yourself a couple borosilicate media bottles, 500ml, with drip lip. Pressure cook with cap sealed no problem 30 min at 15psi. Stop being cheap, and stop for the love of God asking ignorant non scientific questions. This dude said why use agar and not spore syringes and the advantages etc.. bro!!! Not even the same anything to compare. Agar is a tool, spore syringes are meant to be used in combo with said tool not one or the other. Just sounded dumb, I'm sorry. Most of you should just buy shrooms, lol.
The malt extract provides nutrients. If you take it out you will have water agar plates which are generally used in single spore isolation techniques to slow down growth. You can substitute malt extract with a bunch of other stuff.
@@SporenSprout, could you please tell me some of the most common stuff to substitute the malt extract? It's hard for me to get it where I live. Thanks in advance.
You can try steam bath for 2 hours. You will know if it failed after one week because there will be contamination growing on the plate. If nothing grows after a week then it’s ok to inoculate.
Loosen the lid before pressure cooking. Make the hole in the lid a little bigger. Don’t go over 15 psi. Make sure there’s enough water in the pressure cooker.
Thanks!! But why would that be? I thought I made the hole too big (wouldn't that be why the water escaped in the first place?), if I loosen even more, won't the water come out more?@@SporenSprout
Another great video I'm going to grab a bottle of Tito's as soon as the liquor store opens it's a great excuse to get myself some good vodka for a change! Is your flow box homemade?
Looking forward to seeing that video for sure! I'm a carpenter by trade so the box construction is no biggie I'm just curious about the HEPA filters and blower motor specs
sorry but I have another question, what are the proportions that I should use for 10 petri dishes? it´s around 300ml of water, 6g of agar and 6g of potato water am I correct?
You need to give up trying to grow mushrooms. 300ml for 10 plates. So 30 + ml's per plate. So you're trying to fill them to overflowing, where do you put a sample. The linear volume of a standard 90mm x 15mm plate is like 22ml. Soooooo, you can't make plates and your comment about agar and spore syringes was absolute nonsense. Stop it dude
Your number is 312ml total. 10 petrie dishes have a total volume of 225. Soooooo you just pour that 87 extra ml's on the floor or drink it or what. Where'd you get this math?
You can use a lot of different stuff to make agar plates. You can even use strained grain water. Sometimes you need just water agar with no nutrients for the purpose of isolating individual spores for breeding. It just depends what is easily available to you and what your goals are.

bro thank you ;)) few weeks ago i was a beginner with liquid culture now i went to making own agar plates 😎
Amazing video, very easily explained and feel very confident in my first attempt with agar . Great job 👏 👍 💯
Fantastic job and thank you so much for sharing
Great video! Why should I use agar plates and not spore syringes what are the advantages and disadvantages of each method?
You should use both. They are both different from one another. Agar plates are a great tool to germinate the spores from the syringe and isolate individual strains from it. Agar plates are also useful for longer term storage of the mycelium.
Agar plates ensure your not using a contaminated spore syringe before you waste all your substrate by injecting it with contaminated syringe
Love your Tito's bottle.
What was the hole in the Tito’s bottle cap for? You never did anything with that.
It just provides gas exchange. If you don’t have a hole in the cap, it will build up pressure.
@@SporenSprout oooh I see. Thanks!
Sterilized it in the pressure cooker
i see that many people use nutritional yeast with this method
does it do anything? should i just leave it out
Awesome vid deserves more views
I appreciate that! 🙏
What's your method for getting rid of all that condensation? That's my biggest problem yet with agar. Plates are flawless crystal clear, but by the time they've sat in the sab and cooled, nutrient plates all get spots. Any advise?
Yeah just pour when the agar is cooled down enough for you to touch with your hand and there won’t be any condensation.
Rack the the plates one above the other
Heat from above plate will remove condensation on below
Great vid thanks. So condensation on the plates don’t matter? Isn’t it better to leave the plates in front of the hood without lids until they solidify ? Or would that increase chance of contamination? I have a flow hood so I was thinking of placing them right in front
Yeah you should cover the plates as soon as possible, you can store your plates upside down and the condensation will not fall on to the agar/mycelium.
hey, great video. quick question: what is the suitable method for storing them? Also, for how Long can you store them before use?
Store them on a shelf at room temperature. Temperature fluctuation draws out moisture from the agar and causes it to dry up around 6 months. Keep at steady temperature for 6-12 months and transfer to new plate before it drys up.
Great video. When you wrap your dishes with condensation how do you get that to go away?

Just asking, do you loosen the lid to your bottle before you sterilize? otherwise it seems like the bottle would blow up from the pressure.
Yes it also has a small hole with tape over it.
Could you put the mixture directly into the Mason jar and pressure cook it like that?
Yes that works well.
100% That's the only way I've previously done it.
I know a guy that does that. Works sweet
Is that roll of parafilm considered parafilm "grafting" tape??
Yes I prefer it.

No I never added yeast to agar. It was a broth for cordyceps and it was nutritional yeast not activated yeast.

Hi I can only find the syrup like malt extract it has a honey consistency can I use this still ?
Quick question. How long can you store agar before transferring mycelium to it?
Until the agar starts drying up which will happen after 6-12 months.
Do you store them in the fridge or just room temp?
What kind of pressure cooker do you use? How many quarts is it?!
I have a 41 quart electric all American but I used to use a 23 quart presto which was fine.
Can I just use Nutrient Agar? what is the function of malt extract? Greetings and excellent video
You can use nutrient agar by it’s self. The light malt extract is used for nutrients when using regular agar agar, which does not have nutrients and will not support healthy growth on its own.
@@SporenSprout Great, thanks for responding, I'll probably use potato water instead of that
Where can I buy Agar already made and what does it do?
Bruh
I have agar but not nutrient rich should I try using some sugar in this recipe?
My agar is the telephone brand
Honestly you only need light malt extract and any type of agar. You would have to mess with the measurements but yes you can replace light malt extract with grain water, honey, potato water, or basically anything really.
How do u store the plates and how long will they last in storage
I store them on a shelf at room temp while they grow and once they are mostly colonized I put them in a mini fridge. Usually good for 12 months or longer like that. If left at room temp they will start to dry up after 6 months.
If you need longer storage, here’s the vid for culture slants:

Hello. In my country it does not allow me to buy: "Agar powder" from Amazon because the audana does not allow it, what other implement can I use?
I’m sure they have agar powder at a local grocery store. It’s a common ingredient in food.
I think it's just jellatine.🤔
Where did you get the big roll of para film? :)

hey man what kinda of pc is that?
Presto 23 quart.
If I’ve got powdered agar what can I use that I may have laying around the house to make plates?
I mean as the nutrient. I have the actual plates too. I’ve heard of potato powder?
Simple and nice process, but what are these things that look like bubbles on top of plates..?
maybe condensation from the heat from the agar mix?
why do you use a bottle and not a mason jar? can you use a mason jar that isn't full?
Yes a mason jar works, the long neck makes it easier to pour.
First of all, mason jars pour like shit, and an empty liquor bottle is just whatever is around. How about you get yourself a couple borosilicate media bottles, 500ml, with drip lip.

You can try steam bath for 2 hours. You will know if it failed after one week because there will be contamination growing on the plate. If nothing grows after a week then it’s ok to inoculate.
Hi what is the substitute of malt extract?
Potatoe flakes or beer yeast
After sterilizing the liquid agar it came out with only 1/3 of the contents inside the bottle! I did everything as you said.. what did i do wrong?
