Running Water Dunk .vs. Trichoderma
    #7631835 - 11/13/07 05:52 PM (16 years, 3 months ago)

It's been several days since the first flush off a coir/coffee grounds bulk substrate tray and during this time it's been in it's normal fruiting environment with the RH dialed back to the 60-70% range, lighting and the constant FAE remained unchanged.

While placing it under the kitchen faucet for it's hour long "running-water" dunk I noticed a chunk of with a tinge of green. Seeing as it was already under the running water, and that it was slowly lifting itself off the casing, I plucked the clump of mycelium away and tossed it.

As this is my first unintentional infection of trichoderma I'm wondering what my chances are of the running water washing enough away over the course of the next hour or so to hold it at bay until the next dunk - about a week from now...

If so, it'll definitely be a huge proof-positive in it's ability to "flush" away mild/newly-forming contaminations...

I would try a bleach dunk. I dont remember the exact % but I am sure someone can answer that. "RR" I have seen this used on the "other" shroom site. Check it out.

I'm rather opposed to using any chemicals in or near my substrate as I try to have an all organic product for my edibles. Quite a little niche market out there if you have any all-organic produce grocers near you...

The only thing I use when cleaning is 7% H2O2 simply because it rapidly deteriorates into water and free oxygen.

If you use tap water, you are not growing "organic" mushrooms. Even bottled spring water has trace amounts of all sorts of things even worse than tap water in some cases. Evian was found to have trace amounts of strichnine in it. But tap water definatly has chlorine in it's contents. There are tolerance levels that are checked at the plant before it is piped out.

I would never use anything that I would not eat the final product myself.

That is as far as I go. I guess I won't be breaking in to Trader Joe's mushroom market any time soon. But I wont be tossing out bulk after a flush or two either.

Actually, bleach is approved for use in organic mushroom farms.

I doubt seriously that the running water washed away the trich. It's possible it spread it even more, but only time will tell. Bleach also doesn't kill most fungi, including trichoderma. Good luck with that grow. I hope it works out. The trich sure won't impact your product or harvest, so if your second flush comes quickly, you'll be fine.

I noticed just the tiniest (4cm) patch of sporulating trichoderma when it was in the running water.  Not being that worried about it, and being the first time I've had an "official" contamination of trichoderma in a casing without having put it there, I just pulled the chunk out under water and tossed it.  It's spores taste very bitter, btw...

A good 24 hours later, it's obvious the infection is not going away but we'll see how long I'll be able to hold it at bay...definitely doesn't look like it'll pose a problem during this flush but this might be it for the tray.  :shrug:

If you end up needing a day or three to finish a crop, try covering the entire area of trich with a damp salt paste.
