Green mold in tub
#26828501 - 07/17/20 09:14 AM (3 years, 6 months ago) |

A small spot of what appears to be green mold appeared in this tub a couple of days ago. It was isolated and cut away, but is reappearing in the same area.
Does it look like mold, and can this tub be salvaged?
Substrate is pasteurized coir / verm with a little gypsum added.

Yes it's mold, no it can't be salvaged. Either discard it or bury it outside and hope for something, but don't keep it near your grow space.

Yeah dude once you see green (trich mold) its all over. You can cut it as much as you want: its contaminated. Most of the time it comes with the spawn, although ofc it may enter in different ways. Your jars or bags were not as clean as you thought. Id move that think out of my house if I were you.

I'm reading about spraying with h202. Any value in that here?

I've had a couple batches in the past with the exact same issue. Most likely Trichoderma which can be very aggressive. On the first occurrence the good mycellium was able to colonize the majority of the tub and still produce viable mushrooms while i would spray the Trichoderma with alcohol and take chunks out of the perimeter as needed. The second time it happened the Trichoderma took over the whole tub and also had areas that looked like marshmallow fluff which i mistakenly thought at first was good mycellium. Long story short it is pretty much impossible to get rid of and requires a deep clean of supplies to eliminate future issues.

The tub is more or less done for. You can now either try to bury it and hope you will be lucky. Or keep trying to save it and doom other grows you may do in the same place.

It has been removed from the grow area. Another similar tub does not appear to be contaminated, so hopefully the trich spores didn't spread too far yet?
How about trying to save the pins in the uncontaminated part of that tub?

Every time you open the bin let alone touch the green you spread thousands of spores, throw the bin away, shower and change your clothes, or you will never get rid of it without a complete cleaning.

As I understand it (and I'm still a relative newb, so please correct me if I'm wrong), trich is extremely common in soil, plants, and woods in general. There are 10 acres of woods behind the house, and active gardening done by residents. So it seems likely that it's always there, and has always been there, but I didn't spawn properly into those tubs? Perhaps needed a higher ratio of spawn to substrate?

Yeah trich spores are everywhere all the time. It’s true though that you don’t want a high spore load in your grow area so I wouldn’t keep that tub around but there’s no need to go crazy, just try not to let tubs go green for too long before removing.
Getting trich before your first flush is almost always from dirty spawn. Trich mold is white so it can get by you in jars sometimes if you’re not careful.
Clean your cultures on agar and work carefully in your SAB to avoid the baddies.

Any way to spot trich while it is still white?

On agar we keep our attention on the patterns and speed of growth. In jars we do the same while also shaking and seeing how normal the recovery is. And still sometimes something slips with, but generally agar work is worth it a hundred times over.
