cobweb takes over coir? VIDEOS
    #11730980 - 12/28/09 11:06 AM (15 years, 23 days ago)

I thought that was impossible.... Lost 3 tubs now to cobweb... Time to bump up cleaning procedures.

Not that you were asking for suggestions, but why else post?  Cleanliness will not keep the cobweb away but fresh air will.  In a perfect world, 100% humidity would be great with constant fresh air but hard to attain without an expensive setup.  Increase fanning or loosen poly-fill if in a tub.

Cobweb on coir is not impossible..  But in a mono tub setting it is unlikely if the mono tub is built right.

i am getting cobweb during the incubation period in my tubs. Cobweb must be from still air since I had all the holes taped up for a while until I started to notice problems. Then I added polyfill to 2 holes in each tub for gas exchange. I also stopped using trash bags to cover the tubs.

Cobweb will not germinate on coir along with other types of mold. But if cobweb is introduced then it has no problem growing. Check your pasteurization and sterilization procedures. I'm afraid being more sanitary isn't going to help. You can bulk a brick of coir, and a gallon or water in a bucket a leave it sit for a month and mold will not grow. I have done it myself. The coir completely dried out before it ever saw mold.

I did not pasteurize the coir. I have learned since then that its better to pasteurize coir.

I agree with day tripper from the sounds of it you are getting cobweb mold from some other source because I duct tape my hole shut while my mono tubs are colonizing and never have gotten cobweb.

Still unpasteurized coir would not allow for cobweb spores to germinate. (Assuming it was 100% coir.) Somewhere along the line cobweb was introduced and took hold before the mycelium did. Although rare, I HAVE seen cobweb disguised inside of jars. Next time pasteurize, like you said, and be sure your spawn is good. What was your spawn ratio?

Ratio of 1:1, 10qt rye and 10qt coir. I layered the spawn and compost in the tub. Next time I think I will mix instead of layer. If the rye jars wear contaminated they would smell right? like something sour?

Cobweb doesn't really have a smell so no the jars I don't think would smell.

Also I would suggest pasteurizing from now on.. Even simple works..  All I do is put 1 brick of coir 2 quarts of verm in a 5 gallon bucket then dump 5 quarts of boiling water over it.. I let it sit till the temp comes down to 98-100 degrees then pour it into a mono tub and add spawn.

In my experience sour has been more of a sign of bacteria. Granted I haven't made a point to smell contaminated jars, only jars that appear to be healthy, but some contaminated jars didn't smell any different or maybe more musky. It's not always sour.

I like to layer. Mixing isn't necessarily better. I get roughly the same colonization times. I have read on here that people see contams more if the mix but that is pure speculation from reading (not my experience). Bottom line, is cleaning the room before you spawn or duct taping the holes isn't going to cause it to contaminate. I tape my holes and put it inside of a trash bag during colonization. I don't get cobweb. Next time take a pic before trowing it away from cobweb. I know the first time I did tubs vs cakes I thought some mycelium was cobweb even though it wasn't.

If I can not smell cobweb in rye jars then how do I detect the cobweb? Maybe using smaller tubs will reduce the risk involved since less rye jars will be at stake? Assuming that one jar with cobweb in it will destroy the other 9 qt of healthy rye spawn along with the 10 qts of compost.

That would work. You just have to look for signs of different species of mycelium growing. It's pretty obvious to tell. Or one thing you could is before you spawn your jars is shake them up again. If they recover then it's a clean sample. I recommend starting small too. I have a harder time getting the moisture content correct in bigger tubs compared to the smaller ones and trays for some reason. High moisture content will cause mycelium to grow slower and give a window of opportunity for contams as well.

Watch for all these things next time: sterile spawn, correct moisture content, and pasteurization.

If you get those right you can't really fail. :shrug:

You can smell cobweb in rye jars.  It will smell like 'dirt'.  The sour or sweet smell is bacteria, but if it smells like garden soil, it's probably contaminated with cobweb or trich, but either way you want to toss it out.  Non-contaminated mushroom mycelium will smell like fresh sliced mushrooms.

That said, always pasteurize coir.  I've often said you can leave it for weeks without it getting green mold, but that doesn't mean it shouldn't be pasteurized before use.

Those videos are a high enough resolution for me to say what that is. It looks like mycelium to me, but it very well could be something else. It's too hard to say for sure without higher resolution shots. Cobweb will look hair and gray compared to white. But the brown of the substrate can change the color of the mycelium as it's somewhat translucent when it's weak.

The first link smells has a strong sour smell to it. So im saying its a bacterial infection. The second link is weird as fuck. Im sure its contaminated to although it does not have the smell yet.

hmm...yeah. I would throw that shit out immediately then. If you do it now outside you might be able to save the tub. But generally if I loose tub to mold really bad I just throw the whole thing away so I don't get my house filled with mold spores. If it's bacterial infection then you can probably get away with disposing of the contents. Just don't wait for the trich.
