Re: AGAR ENVY! (Anything and All things agar!) [Re: Kloakk] * 2

Was wondering if maybe the agar itself was an issue, I used grain water from processing sorghum. Ran it through a coffee filter post grain boil, then reduced it a lil, and filtered it again, then froze. 500ml of that to 10g agar powder. It's definitely pretty firm, but there is/was lots of condensation in the plates. I understand that using 100% grain water is kinda loosey goosey in terms of nutrient content being an unknown. I have malt extract powder for the next pour.

Grain water is fine, I've done 50/50 grain water/ plain water and 25/75 grain water/plain, both worked okay. Try the DME(dry malt extract) next run and see what you prefer :rockon:

And again try storing you plates standing up at an angle and see if you get bacterial runs.

I really like grain water agar, just don't like not knowing what the actual nute concentration is. But then my go-to agar is Milkboy's PDA and I'm not sure there either but it works great and is crystal clear (and I'm a potato).

Sick :rockon: thanks for the reassurance and for the tip on storing the plates vertically, that's a pretty cool way to get bacteria to do something differentiable. We shall wait and see. Really hoping at least one of these shakti plates does something, they look soo cool. Definitely having fun with agar so far.

Agree, grain water is pretty sweet, only tried wheat. I'm still on the fence though because I've only done 2 GW pours(60 plates), my pans moved really fast, cubes looked a little thin but still did the thing fine.

I just made a batch of 1% DME plates with 0,2% nutritional yeast and will use 50/50 GW/plain with 0,2% nutritional yeast next time I do grains and compare different species on the different plates and see how it turns out.

With GW plates I need to plan ahead if I want clear plates, so will see what I'll settle with.

Aaaanyway :blah: :blah: :blah: Point being nutrient value doesn't matter if the plates looks good and the mycelium is happy.

Happy to help man, when I plan on using the grain water for plates I take the extra time to rinse my grains thoroughly before boiling to at least get the bioload down a little.

And yes the vertical plate will give the mycelium a chance to outrun the bacteria, of course bacteria can piggy back along, but in your case I just thought it would be a good way to check if the watery look really is bacteria or if there was condensation giving the mycelium that wet look.

If things improve by keeping them vertically I would do a new transfer into a cabin, the cabin is, in my opinion, the best method for getting rid of bacteria.

Super appreciate the help :cool: I definitely gave the grain a really good rinsing preboil, mostly to get chaff and other bullshit out of it. I'm wondering if some of the "wet look" is due to the swab chunks being somewhat submerged in the agar, I def shoved them in there a lil bit :naughty:

Sure it could be a lot of the mycelium germinated inside the agar and why it looks wet, time will tell, keep us posted :awesomenod:

This is the most naturally challenging kind of plate to diagnose IMO, because it's in that "kiiiiinda" state where it could go a lot of ways and the best move is to let it play out a little longer and see.

I chased down some of those wispy outer rings awhile back and was originally so sure that there was a wispy mold chasing me across tons of plates and solid technique, but with another week, they fluffed up into normal (if a bit tomentose) mycelium.

5 to 6 PM on that first plate does look like there's a thin slightly cloudy cluster overtop of the mycelium. Photos can be hard (glare can do weird things, myc strands can be blurred by the camera into looking like one cloudy mass, etc), but anything that's in the "thin mass of mucus-like jelly" is gonna be bact. +1 on kloakk's vertical tip.

Keep an eye on it, if you have other plates ready and feel good about your SAB stillness, you could just snag a sample from the opposite side of the plate and perhaps not have to do cabin work.

--

for swabs a slice (if you literally cut it) is a bit unusual and I'd mostly worry about contam from the cutting instrument (if more than the flame sterilized tip touched the swab etc). But anything goes for getting it on there, it's common to literally jam the whole swab in there and leave it sticking out like a flagpole (though that consumes the whole swab).

The approach I'd recommend is tweezers, narrower the better. They're easy to flame sterilize and you can snip a few strands with visible spores from the swab and place them on the agar, which keeps agar off the swab and also preserves a lot of material for future attempts.

glad to hear you're gonna wait on it for a bit, good move imo

Curious about y'alls "unintended" tools for your agar work?

I use a blackhead extractor tool as my inoculation loop when working with spores. Works great with the grab and drag

Okay so we got this super clean T1 clone from a very white Australian landrace fruit first flush from spore. Next is some Gandalf I received.  After that is two KOH samui swabs from the same generous user I can’t remember off the top of my head who. Then a PE6 plin and then some toque f13.

Hey everyone,

First time doing agar. 10 plates, PDA, used an MSS, single drop on each and spread around with a cell spreader all inside a SAB, etc. It's been 5 days. Of the 10, 1 has no growth (yet), 2 have pretty large green spots of mold and the remaining 7 are pictured below.

Yeah, I used way too much cling wrap and need to label each plate LOL

Also, in my attempt to get clear pictures, I backlit the plates against a window so they look darker than they really are but they're all white like picture #1 except for #5 which does have a dark mold spot.

I've been reading through this thread and others but would appreciate some experienced eyes on whether I have anything usable, when to transfer, etc. Thank you!

For those of use using cabins, do you pour your plates a tiny bit deeper and use them specifially for cabins?

Re: AGAR ENVY! (Anything and All things agar!) [Re: droner66]

I have when I poured mine because I use condiment cups instead of Petri dishes so I can do a bit deeper but I don’t over do it.

Plates are ready to go. Should I do transfers now? Which plates? I was thinking #2 and #6...

I've read some TCs mention for initial transfers, not to let it grow out too much. Thoughts?

il streak a plate then il transfer the germination points i want to new plates to let them grow out about the size of a nickle or a qtr. then il take a cpl transfers from there to new plates and let them grow out to about the size of a qtr.

Yeah those are both good I’d take the bottom part from 3 to 6 o clock if it was me but 2 is promising as well just take a really small piece and then wait. You should have some nice growth take it to a T4 maybe T5 and I’d spawn but you could spawn at T3 if you can’t wait if your sure it’s clean but I tend to take a bit further when I do it from spore

Super appreciate the in-depth response 🙏 thank you. And yeah, I literally took the scalpel and got 5 little "fillets" off of the swab lol. I'm assuming the swab was made via swabbing a fresh fruit, as there were gill fragments on it, and it definitely had a texture that suggested it had been wet and then dried out, so the outside of the swab was almost like a skin/film if you will, which made the filleting easier tbh. But I really like the tweezer suggestion, if I ever work with swabs again I'll definitely go that route. Nothing is seeming to be overtly bacterial somehow, though the plates look a little crazy, im guessing from the giant mixed bag of genetics going on. But I decided to make some transfers tonight, as some of the plates were starting to develop areas of nice looking rhizo growth, well see what happens!


Was particularly proud of how clean this transfer went/looks


Tried my hand at a cabin for the fuck of it, shits kinda hard lol

Was taking some samples from a MS streak plate tonight and found this lil guy. An example of something I like to see.

I do sequential horizontal drags (not a zigzag). Clearly most of the spores came off on the first few drags, becoming that big mass of various germ points.

But much later, there's one teeeeeeeny little uniform, wispy germination. I took the tiniest bit I could from the edge of the colony, trying to avoid the streak line itself (where other spores could still be).

I label these as possible monokaryons, and if they show promising growth (slow, even, non-rhyzo), will check for clamps.

Plannig on posting a full mono hunting tek in early/mid sept.
