Diving into agar pouring your own?
    #26497850 - 02/22/20 12:01 AM (3 years, 11 months ago)

Alright, going to be honest here. I had it in my head I was going to order my no pour pasty plate items last night.. did some more reading before I did. Decided Ill do it today, but found some posts/comments saying pouring your own is the way to go, and it has enough pros to be recommended. So many different opinions it, I feel like I should just start with pasty plates. What do you guys think?  Also check out these containers/dishes, what do you think?:confused:

Pouring your own gives you better visibility than the pasty plates.Also pouring is very fast and easy when it get the pour down, once your hand remembers what to do. Pasty plates are awesome tho, but my only gripe is the visibility on the containers. The plates have less condensation and more surface area then the smaller plates.

Mr. Alien's no-pours look pretty legit. I've made pasty plates before, and don't like them (poor visibility).

Personally, I prefer to pour. The only way to find YOUR preference is to try both:shrug:. One will click with you more than the other.

If you are interested in pouring check out the guide in my sig, should be helpful

I always pour and use real plates,scales nicely that way

I like the link to your agar tek. Will be reading that thoroughly, as I am hooked on reading. Thank you. It looks like ill be buying the containers Mr. Alien posted about. I mean, they can go in a PC so I can try some pour and no pours out. Why not you know? Is there any reason why I shouldn't do both pour and no pour in these containers? Is it better to buy disposable petris as well?

Dog just buy a case of petris, a media bottle (or use a glass whiskey bottle) and some agar and media. 1lb of malt extract is 15 dollars and 4oz of agar is 10, petris are about 70 and you should def buy a case. Best route. I promise.

The containers you listed are great for no pours, but they will be difficult to pour like regular petris because of the twist off cap.

For pours, petris are the only way to go,  honestly.

PP5 is the only requirement. Be aware some containers are PP5 yet the lids are not. I don't think this is common though.

Pouring your own plates feels preety good. A 20 stack of the plastic ones all poured perfectly cooling in front of the hood is always an awesome sight to behold.

Pouring plates is stupid easy once you do it a couple times. Riding a bike seems like a arduous task to a toddler but to anyone else its as easy as riding a bike.

Just use the disposable plates, not the glass ones. They are like 70$ for 500

If you are like me, you'll end up using 10x more than you think you need

Pouring was easy for me, I started with that and pasty plates. Just watch a video, and visualize what you're going to do a few times before you actually do it.

Pasty plates can be easy to see too:

I think Aliens HG container is better than the pasty so i bought 40 of them and 20 normal sterile petri.

Differences i see so far:
HG containers can be poured in the open with out worrying about contams because you're going to PC them later.

Petri you must PC the agar before pouring in a SAB and sealing each with some kind of wrap.

Trade offs: HG containers have screw lids so no wrapping needed, less worry about contams from pouring, reusable. Petri: more surface area,slightly clearer, quicker/easier to work with stacks as lids lift off easier (no threads),can't be reused and theres too much plastic waste.

It's only "difficult" the first time in that you've never done it before and are learning a lot of things in the process.

you can see myc much easier on real plates, and it scales better. it would take ages to do 80 pasty plates, vs a couple of hours to do 80 regular plates. i could easily pour 500 petris in an afternoon

pasty plates are great for small scale though.

agar work has a tendency to multiply into a TON of plates, so its much easier for me to work in bulk. im also a gear whore so i like using the same equipment the pros use, since it was developed for this exact purpose

It's a little awkward if you use something other than a media bottle. With a whiskey bottle there's a little twisting
wrist motion that you have to get in order not to make a mess. With a media bottle you can just pour.

Honestly, I've never understood the allure of no pours. To me, it's just trading one kind of work for
a different kind of work...and the lack of visibility sucks.

Pouring is easy if you are quick. Open the plate, never put your hand over anything sterile,. When you pour, lift at a tilt so your hand holding the lid is not over the dish and your pouring hand just pour, it only takes a second, then close the lid. It helps if you have a stack of five, start with the bottom plate, lift the lid and the stack, quickly pour, then move up to the next plate , repeat. You can pour one plate in a second or so.

Another vote for pouring your own.  I made plenty of mistakes on my first attempt, and still had 95% success.  Every time after that was easy since I knew what to expect.  Bod's guide and c10h12n2o's guide are gold

How many plates do people typically start with (I'm inoculating from a syringe)? I should probably expect 1-4 transfers if I'm just looking for clean MS, not going for monoculture, right?

I have ordered everything I need to pour my own but I already have 15 pre-poured plates. I was planning to inoculate 2 or 3 of them, and I want to be sure I have enough plates. Do I even need to start with 2 or 3, or is one plate an adequate starting point?

I have always worked with MS syringes but this time, once I reap the harvest, it's Clonesville for me.

I always buy a case at a time, cheaper that way

Depends how many cultures you run at a time. Agar work has a tendency to multiply. For example I started a project recently with about 12 plates, and on t2 it's already become more like 80.. but you might not be as OCD as me

Definitely not :wink:

For this run I'm trying out Bod's unmodified tub Tek and I just want to make sure I have clean mycelium to inoculate 6 quarts. I've been using spores straight from the syringe up until now and, despite being ultra-careful in trying to create sterile conditions, I lost half of my previous 8 (modified) tubs to contamination.

So, dipping my toe into agar before attempting a swan dive.

If it was me, I would use the streaking method in my guide, use a drop or two of solution per plate, for each variety you are working with. Then transfer myc a few times to make sure its clean, then do either agar to grain master jar (then grain to grain to make more jars), or make a liquid inoculant and use that to make grain masters (NOT a liquid culture)

C10, I have a question about your streaking technique. I have seen pictures of a lot of plates that have a blob in the middle with the sectors fanning out from there. I can see how streaking covers more of the surface but doesn't it make it more difficult to tell what's going on with mycelium development?

Re: Diving into agar pouring your own? [Re: Igloomis]
    #26502471 - 02/25/20 12:23 AM (3 years, 10 months ago)

The purpose of the streaking technique I'm talking about is basically to do a serial dilution on the agar surface. This means that in zone 1, there will be lots of spores (and possibly contams), while each subsequent zone will have less spores and less potential contams, and they will be spread farther apart

Basically you would transfer myc to a new plate as soon as you can. This is a good idea in general when working with spores, since they are typically filthy.

Keep in mind that MS cultures have countless strains intermingled within the colony. On a serial streak, there will be more in zone one colonies, far less in zone 5.

Typically I transfer healthy colonies as soon as I can, often 2 or 3 to a plate. So I might take 5 transfers from a streak plate.

It's not about surface area, it's about trying to get clean colonies , and optionally colonies with less intermingled strains.

You dont really want to let the myc develop too much before transferring it from a spore plate. You'd be watching the development on a subsequent plate, after the transfers.  The goal is to get clean , well organized mycelium,  so typically you should do at least 2 or 3 transfers after the spore plate before actually using the myc to inoculate, since this reduces the possibility of contams from filthy spores, and let's you select aggressive/rhizo/healthy sectors (whatever you are looking for).

Lemme see if I have something on hand and I will post examples

This is what it is supposed to accomplish:


The goal isnt to cover the plate with myc, but rather to isolate clean colonies with less genetic diversity and contams than you would get from simply dropping spores on the plate would result in

You then transfer these colonies and grow them out on other plates, and continue transferring good looking sectors until you have clean, well organized myc

I dont have any great examples unfortunately since my streak plates are all way past the point where i transferred colonies, but maybe you can tell from these pics :


This was the streak plate. I only had germination in zones 1-3 , and I transferred 6 of those those  colonies almost as soon as I noticed them. If you look close you can tell when I did the transfers, about 10 days ago


This is one of the plates I transferred the initial colonies to (transfer #1), and you can see where i took transfers from these about 6 days ago


Here are 2 plates from transfer #2 . Notice how much better organized and rhizomorphic (and faster) these are than the previous plates. They are also much cleaner since there are no spores, so less vectors for contam

These last plates are probably safe to inoculate with, but I will probably do a few more transfers

Does this make sense? Are you getting an idea of the purpose of this technique? It gives us many genetically different colonies to choose from and test/grow out

It’s kind of like, rather than trying to find the nice families in a big city, you’re spreading it out and finding them in small villages. Definitely learned something today. Good question, good answer. I’m glad I bought a loop as well today, I actually got it because of your tek and you talking about it. I’ll be starting my agar when my items arrive the 26-27. Thanks for the good convo guys. Catch you tomorrow.

That's a great analogy for it. Cities also harbor more disease (contams)

In a big drop of solution, there can be thousands of strains comingling to form the visible mycelium. By spreading and diluting that drop into different zones, the concentration of spores and contams is lower in each new zone.

Often what people think is tomentose myc is actually many different kinds of myc growing through each other.

Serial streaking/dilution helps by creating myc with fewer intermingled strains per colony, and also fewer contams. So it can be really useful whether you #1 just want clean myc (should be the goal for newbies), #2 want to grow out several cultures from the same sporeprint/syringe on agar to find aggressive/rhizo growth, or #3 want to work towards isolates (or at least well organized cultures)

If you could germinate only 2 compatible spores, you would have an isolated strain. But since there are countless spores per drop of solution, unless you do a serial dilution you will have colonies made up of countless intermingled strains

Even with serial dilution streaking you will still most likely have multispore colonies even in the later zones, because spores clump together. But each colony will be genetically distinct from other colonies, and comprised of far fewer strains per colony than they would be if the spores were not spread out. This is great for transferring out lots of different genetically distinct colonies to fresh plates, then picking the best looking ones to move forward with

Also the to illustrate the reason for transferring colonies from the streak plate asap:

Notice in the pic of my (overgrown) streak plate, you can see where in transferred colonies, but now that it has grown out you cannot distinguish those colonies from the countless other colonies that have grown over and through the ones I chose to transfer. This is why you transfer them early before they become intermingled and indistinguishable

So do you want to grab a small clean colony from the first plate when it's about as developed as the first picture, or do you let it develop a little more, somewhere between the first and later picture?

Just 3 more things:

1- Thanks, CatsLoveHouseMusic for starting this thread.

2- C10, what temperature do you recommend for growing cultures?

3- C10, I am going to do my first inoculation this weekend. Will you please stay tuned to this channel so I can post pics and get your feedback?

Thanks again! Oh, and did I mention how much I love your flow hood?

The first pic in the thread is actually of bacteria, but the same principle applies.

The streak plate I posted is WAY past the point you'd take transfers. Typically I transfer colonies when they are smaller than a pinhead, basically as soon as possible

You could wait longer and probably not have issues, but the colonies will quickly overlap and intermingle, losing their genetic distinctiveness

Again this is bacteria not myc, but this is about the point I would transfer colonies, with the colonies I would transfer circled in red (very tiny)

2. You are fine just storing them in room temperature.  Sometimes I keep them closer to 80 is I'm I'm a hurry, and technically you could go as high as 85 but contams benefit from that more than the myc does

3. Sure no problem, pm me if I miss it and I'll come post in the thread again

Thanks, I love it too :smile:

Just did my first attempt at inoculating a dish.

I'm using pre-poured MEA plates from a mycology specialist supplier to simplify my first try. I kept the dishes in the refrigerator until the spores arrived. The refrigeration (I assume) had caused condensation to form on the lidsof the plates. One of them had minimal condensation, so I inoculated that one and left the others in my SAB to warm up.

How concerned should I be about condensation?

Also, I had a bit of trouble gauging the rotations of the plate between loop flamings. I think next time I'll put a mark at 12 o'clock for reference.

ETA: As I was inoculating I noticed my syringe said Golden Teacher. Damn, I was sure I ordered B Plus. I checked the order and sure enough, they sent me the wrong spores. I have grown GTs before; this was supposed to be my graduation to something new.

Yeah I use a sharpie and right on my plates around the putter edge on the face and back of plates. I make all kinds of notes and sector labels. Then when I wrap the plate in my little roll of plastic cling wrap the sharpie ink is protected from when I wipe it down with ISO later.

So you don’t streak plates? May I ask why? Curious

How long until I should expect to see growth, given a 72-ish F incubation temperature?

The pic he posted is a transfer plate not a spore plate. But lots of people don't streak, it's not mandatory by any means. It has lots of benefits tho

Growth from spores? Could be 4 days, could be 3 weeks or more. Hard to know. Usually within 10 days

Quick followup.

My plate lids were covered with condensation, so it was very difficult to see what was going on. I probably should have waited a bit longer. I picked out two pinhead-sized isolated colonies and transferred them. I now have two beautiful dishes of well-isolated contaminants! :tongue:

I made another attempt this morning, this time working from a spore print. Before inoculating I turned both top and bottom of petri dishes upside down on an alcohol-saturated paper towel in my SAB and tapped condensation droplets off the lids. Then inoculated and sealed with parafilm.

Let's see what happens this time.

Condensation is a battle.  Pouring as close as you to the setting temp helps to cut down on this.  Also can help to keep them in stacks which clears up the condensation for most of the stack.  Sometimes storing them upside down (after they have set!) helps.

condensation :machinegun:


Pinhead size?  A bit too early to tell, did you have any magnification?  Dime-size to quarter-size will let you identify the myc you want

Here's where I am with my first agar attempt with B Plus. This is after 2 transfers from original inoculation from a spore print (so, 3rd generation). It's not monoculture but it looks clean and even, so I'll be taking it to grain in a couple of days.It seems like it has taken a long time, but I guess a week isn't bad for this much development.

Definitely not even. I'd do one more transfer at least, if it was me. From as far away from that patch as possible

Itll probably be fine if you dont, but still worth cleaning it up a bit

I'd grab 7 o'clock,  and maybe 12 o'clock and 5 o'clock too, but I like redundancy

I meant even as far as no wild fuzzy patches like in the source I took it from. I did one more transfer but I went ahead and inoculated grain with the rest. I did an agar wedge inoculation (never tried that before). I hope it works. If not, there's another transfer right behind it. Oats are cheap :smile:

Just a bit of follow-up.

I continued to transfer on multiple lines of dishes, but all of my efforts resulted in green mold, despite extreme care in all aspects of my procedure. At the time I was using only pre-poured plates purchased on the internet. I went back to the drawing board and stepped through my entire process bit-by-bit, eliminating variables: sanitation, technique, sterilization, jars, lids, oats, etc. I finally got around to pouring my own agar and, voila! no more contamination in my oat spawn. I can only conclude that the pre-poured plates (which had a very cloudy appearance compared to those I later poured myself) were the culprits. I have six quarts of spawn going now with good colonization and no sign of the green meanies.

Moral of the story: just pour your own damn plates. If you think you're saving time and cutting corners by paying someone else to do it you might be fooling yourself (and spending a lot more money than necessary). And it's fun once you get the hang of it.

I just went straight to pouring my self, easy and cheap... why not?
The HG containers make it even easier, pour em on the counter let cool, load up in the pc, take em out and crack the lids till condensation clears. ez low effort

A alternative is polypropylene petris if you dislike plastic waste. They are able to be pcd and reused. The trade off is you only get like 80 % of the disposable petris visibility but alot better than pasty plates about the same as holy grail plates. They are fine to see through in person if you shine a flashlight on them but suck for pictures
