Is it green mold?

Hey Shroomok

I followed your guide and finally got a beautiful tub with many small mushrooms popping out Could you check those cakes? I worry about green thing on mycelium (bottom part of photo), is it trich? If so can I rescue small shrooms?

Hello!

Yes, unfortunately, it’s contaminated. Most likely it’s an early stage of Penicillium mold, which typically turns fully green in 2–3 days, whereas Trichoderma usually turns green within 24 hours.

Please don’t cut the contaminated area, touch the cake, or fan it! Instead, let’s try a workaround: apply salt (or baking soda) directly to the contaminated area (I've marked them on your photo with red circles).

You can either:

1. Pour salt/soda directly onto the contaminated spot OR

2. Soak a paper towel in salt or soda solution, place it over the contaminated area and pour some dry salt/soda on it and around the edges (see example from the guide).

This method helps seal off the contamination to prevent spores from spreading, slows it down, and may allow you to save this flush.

Feel free to show me how you applied it—I’ll be happy to take a look and give feedback!

Thx! I thought its done

I made a salt application, is it ok?
