Yellow contamination?? Pics
    #23427057 - 07/09/16 04:13 PM (7 years, 6 months ago)

Ok, I know these topics are pretty beat up but I cannot find anything that looks just like this even on google images...

This is my second run of BRF cakes.  I have cleaned everything out since the first run, new perlite and everything.  First run went well.  Had around 20 cakes and ended up producing 2.5oz or so.  After 5 cycles many started getting very obvious mold splotches so I scrapped it all.

Anyways. This cake hasn't even fruited yet and is already showing discoloration. In jar until pin, soaked for 12 hours or so.  It is Cambodian strain.  The other cakes in batch are showing similar yellow discoloration.  I haven't changed anything in my process.

Metabolites

They need to be rolled in verm

I did try that on some of my last batch.  Birthed cakes, soaked.  Heated oven to 250 or so and spread out Verm, thin layer and baked for 15min or so to sterilize.  Wet cakes and rolled.  They seemed to take much longer to start fruiting, produced less and got real contam faster.  Is there something I'm missing?

depends on a lot of factors, if you soak longer than 24 hrs, contam risk increases

your contamination source could be living in and producing spores in your FC as well, especially if it is the same FC, new cakes can succumb from remnants of old contams

to prevent this, warm soapy water wash the fc if any contam occurs

I completely disposed of all old cakes, perlite etc.  cleaned out FC very well, bleach all over inside and out.  I usually only soak 10-12 hours.  Pretty easy to get a feel for when it's fully saturated.  I'm trying roll again now with cakes I removed from soak a few hours ago

That looks dry as fuck, probably why it turned yellow.

Changing the perlite and bleaching the FC is totally a waste of time and money. If you are seeing contams early in the game, it's not the verm's fault, the cake was contaminated during inoculation most of the time. Verm has little to no nutrients and contams cannot germinate on it.

Check your inoculant and pick apart your sterile tek, the fault is somewhere between those two.

:whathesaid: you can also try and use as little spore solution as possible, as it could be a vector.

Washing the FC is useless. :facepalm: Fruiting is not a sterile procedure and it has no reason to be. If you are not capable of clean spawn/cakes, no amount of washing and bleaching will save you from contams.

Ok.  There's some misunderstanding.  My last batch easily made 5 fruit cycles before I started seeing real contam.  I JUST cleaned out chamber very well and replaced perlite. Yes I know I didn't have to but I don't care about a few dollars. 

They are not "dry as fuck" that cake was just soaked and fully saturated a few days ago.

No that's bullshit. Keep you spore load down. I don't care what people say.

:lolsy: Wouldn't it be nice if you can get rid of spore load by just washing your tubs? That's gotta be the most ridiculous thing I've heard this week.

Newsflash, spores are microscopic and can hitch a ride on dust particles, stick to walls and stay in the air for hours at a time. Goodluck getting rid of something you can't see. :facepalm3:

Spore load also has very little to no effect on healthy spawn. Keyword being healthy. You can take a dump on a healthy tub and it won't contam, that's one of the wonders of good sterile tek.

If I wasn't a lazy fucker tonight I would quote Mad season saying that he hasn't changed his polyfill for years and it is all black due to cube and mold spores.

:thisisterrible:

Try going a few days without a drop of water. Dunking is not nearly as efficient as you think it is. You still have to mist at least 3 times a day with cakes, even more since you didn't coat them with verm.

This thread is halfway down the shitter already.

I did take half of them and got a good coating of sterile Verm on them.  We'll see how they do compared to the others.  My yields all seem pretty low.  I'd say I avg 2-2.5gr dry per cake per cycle.

This batch I have been only misting the walls of FC once they are about dried out.  My last batch, which I was much more heavily misting people said too much.  I was getting fuzzy feet etc.  I'm still seeing fuzzy feet actually.

So why is there no glistening water on the surface? Dude you can deny it all you want. The surface looks bone-dry. Some people have to mist directly(not the walls) 3 times a day, even if it's covered in verm..

Wow. You only have to be sterile in your still air box, and since its application is to keep air still, the sterile component is dependent on your procedures.

Yeah if we're going to go into spore loads.. I live in a 70s farmhouse with 4 dogs and horses. I had this lost in my basement for pretty much the entire winter with the furnace turning on every 20 minutes, and I still grow just fine. I got spore covered chambers with the same spore covered poly from 2012.. Clean spawn is what is needed in this situation. Keeping spore load down will help if you can't have clean spawn, but if you can actually get clean spawn, you can spawn that shit next to a cobweb infected trichy af monotub.

Here he comes to save the day. :wave:

OP, what you basically did was go from one extreme to another. If you were misting too much, now you are basically not misting at all. Misting the sides is useless, the cake cannot drink humidity, it needs water. If you are seeing fuzzy feet from a bone dry cake, your FAE is too low, check if you are following the SGFC tek perfectly, meaning hole placement, size and quantity as well as elevating the FC a few inches off the ground.

If you still get fuzzy feet from following the TEK perfectly, add some more holes. The only time I used a SGFC, I had aerial mycelium as well. This is one of the reasons why I prefer monotubs and bulk personally, you can dial the FAE to your needs while with a SGFC, you have to fuck around with a driller or a solder iron.

I'm still trying to figure out the yellow line on that first cake. It almost looks like something was leaning on it or something.
