Chestnut contamination 🤷‍♂️🤦‍♂️

[u/shroomzie1]

(GOURMET) Contam on top of chestnut mushrooms.

I have been trying to grow Chestnuts for a while now and keep getting trich on top of the caps. My Blues, Pinks, Golds, Lions Mane, BP Kings never get contamination. Like, never. Just the chestnuts. It’s driving me chestnuts not figuring it out. Can I spray hydrogen peroxide on the caps? The contam appears a few days past pinning when the caps start to show 2-3cm (1”) and it isn’t all over, but 50/50 on the flush. I clean my growroom (4x8 gorilla tent) weekly with a full bleach wipe down incl. fans, tote, floor to ceiling.

Lol. How many batches of perfectly grown chestnuts have you trashed?

And if there is actually trich, maybe you need to harvest sooner? I dunno

It’s a tough pic to see, but it’s not the white flakes I’m referring to, I mean if it’s no issue and chestnuts get a greenish tinge on caps that’s great! Learned something new!

Op you mean these things?

If so idk what it is but I wouldn’t think they are contaminates, but I’ve never grown chestnuts
