Agar Issues

How long on average does it take for an isolate to take on a new type of agar? I place an agar piece on a new agar plate on 9-29 and it has not even begun to grow? The plates look clean, but some have condensation. I just cant seem to avoid these problems, how the fuck do I avoid this? My agar transfer is just growing on itself and not the plate. WHY?

EDIT- I think I added too much agar to my mix around 15 grams for 650 ml of water, 10 grams dog food, 2 grams karo, 2 grams BRF. Are these ratios okay, my mycelium is unusually hard and rubbery, I tossed one of my plates and felt it.
Any idea

That's a pretty complicated agar recipe. Why not just stick with a basic malt extract agar and use 4g of agar and ME per 100ml?
And to answer your initial question, you should have seen growth by now, yes. Only takes a few days if all your ducks are lined up.

That's far too nutritious. Leave out the karo and brf next time. RR

Wait LOL are serious!?
So should I have just used say the dog food? And could I possibly just dilute my flask by adding 250ml and PCing again? Im really screwed here, Iv'e been transferring this for 4 months and finally Iv'e gotten fruits to produce around 2 grams dry per agar dish and they seem stellar. Anyway I could just grab the mycelium off of the other plate that's growing and sand-which it between another new dish and fresh agar? Thanks again RR

All i can guess is fruiting from agar. this is why OP uses so much nutrients?

than you would still have to have quite a lot of agar to have enough moisture for fruits of 20 grams. do you have pics OP?

Fruiting from agar? That doesn't sound like a very efficient method

This makes no sense. What are you saying?
Let me clarify for you FRANK Awhile back I found an old spore print from a very old grow found in a Simpsons Christmas special DVD. I then used those spores to knock up a whole sleeve of petris in open air with a Qtip, don't give me shit for using Qtips, I use those in place of inoculating loops and they are completely sterile, I grab them from the hospital I work at. So anyway 5 of those in that sleeve ended up being contam free and from there I did a couple of transfers and ended up with 3 dishes that I liked. All three of those dishes were left in my storage container and fruited. I don't want to fruit them in agar dishes(that was not my objective) but they yielded 2 grams dry give or take per dish. I grabbed one of the fruits and did a tissue transfer from the inside stripe. I gave those dried specimens to a friend and he was very pleased with how 1gram of those fruits reacted with him.
To simplify I have been doing agar transfers for about two years and all the dishes I have in storage are okay, but none and I mean none come close to how this one particular plate has reacted with me and my friend. I mean straight  and never even indulge in such activities anymore. Basically I want to save this specimen but I cant because I used this fucking agar recipe and got fucked over. I never even knew that agar could be too NUTRITIOUS, so now Im left with 3 plates that is just growing on the transferred piece of agar.
SO PLEASE HELP and give advice.

I wasn't purposely trying to fruit on agar, but from my experience its best to let your agar fruit by itself and see if it can even fruit before doing A2G and coming up with a tub full of shit

Sadly I dont, but I think I might have one with a cluster pic, I'll look. To be honest I have no idea how to upload pics on here and feel sketchy doing so... but could I just upload them from my phone?? I got great pics of plenty of strains from cubes to shiitake to just random specimens found in the woods of Wisconsin and Illinois if your interested...

My understanding is, and I could be wrong, if you fruit on agar then that culture is in fruiting mode and does not respond well when switching back to colonization mode.
If this is true, then you could avoid the issue by just fruiting a transfer from a master. Once you see that it fruits and is potent, then you can just go back to the master.
However, just because it does not fruit on agar does not mean it won't fruit on a properly prepared substrate.
The reason I say I could be wrong about my initial premise is because it seems to me that a clone from a fruit would also be in fruiting mode and a fruit is basically mycelium anyway. 
I can see your agar fruits being small and potent. I typically pick my fruits smaller than most people probably do. My friends and I have done some experimenting and have agreed that I should pick them before the veil breaks or get too big.

seems the mushroom doesn´t like substrate. I had something like that before with an excessive sugar content. did you use exactly the same recipe for your other transfers before?
15gagar/650ml is much, but some people use even more. agar actually doesn´t do any harm.

On the matter of when to harvest fruits I say it depends on what you find preferable, I agree, picking early is a better ratio for potency of cubensis. It isn't necessarily that the mushrooms are more potent, its more so along the lines of water dilution within that mushroom. If that makes sense. In most edible mushrooms its also better to pick before they mature, as some species seem to get rather rubbery and tough out on the outside.
Honestly I haven't heard of fruits on agar not producing a network of mycelium. Usually fruits are vigorous when placed around nutritious mediums but you could be right and the times I have done I've gotten lucky. Let me know if you can find anything on that matter.
And trust me, you can add too much agar. I think that's my culprit right now and RR pointed that out too. It feels like rubber, and the agar piece I used to inoculate the dish is growing rapidly. I might just make some more dishes, and transfer a couple of slices of the initial transfer, and maybe shoot up a couple of grain bags with some new Agaricus brunnescens MS I just whipped up. Im just going to do 2 1lb bags and case them with peat moss.
I'll get back to you and see if I can save this prized horse or if its going to end up in my bed like the Godfather HAHAHA
PEACE

No thats the problem, usually I buy premade mixes of PDY but I ran out and never ordered any. So I've been playing around in the kitchen trying to make new recipes. I think I'm going to stick to the OG recipe I have, let me know what you think.
250 grams of potatoes cut up and boiled in 500ml of water, boil for 10 minutes and strain. Removing the actual potatos and having a broth left. Then add 2 grams of karo and thats it- besides PCing. Is that too much karo in your opinion? I might use the dog food again but I dont like having too much sediment in my dishes.

For 500ml I would use 10g agar, the rest of your recipe sounds alright although I use dextrose rather than karo.

Definitely will be adding 10grams Where do you usually get dextrose and what are the advantages, I thought karo is basically the same as dextrose which is just corn sugar. I was going to head to a local brew shop on Monday after class and grab some light malt extract.

No, there is no problem with karo, I just haven't tried it before because I haven't seen it for sale anywhere.
I got my dextrose from a supermarket, sorry I can't help you, I'm in New Zealand.

Here´s another potato agar recipe from a mushroom cultivation book, which always worked out for me:
300 grams potatoes 12 grams dextrose a tea spoon of beer yeast (I use 7 to 10 grams fresh moist baker´s yeast) 1,1 litre water (refill what has evaporated; I sometimes use some more water, but the original recipe is okay) 25 grams agar (I ussally use less then half)
dextrose is a monosaccharid, which is a bit easier to digest than the disaccharids saccharose or maltose, because the mushroom needs lots of enzymes to crack glycosidic bonds. Karo consists of dextrose and a few percent fructose (also a monosaccharid). Honey is also mainly monosaccharids.
And what os OG again?
