King Oysters not looking so kingly

#29723371 - 11/10/26 12:16 AM (13 hours, 7 minutes ago)

This is my first time actually getting king oysters to grow (shout out to all the bad suppliers out there) and they're not looking so great. :frown:

I'm assuming its because of not enough humidity but they are in a grow tent and were sprayed every day on the pH balanced casing.
I had a few sitting on top of an open bucket and the bottom seems to be doing well where a lot of the humidity was higher. Since they are in milk crates I was hoping for more side/top pinning. It would explode with pins and then most would stall out and then turn into these fatties with tiny crowns. :P They look cool, but I would like them to grow normally and ...more obviously!

Stamets book says fruiting should be (will have to consult the book its not by me right now) 80% humidity and in the mid 60s Fahrenheit temp-wise

Any ideas? Humidity? Temp? Im thinking humidity, it does look like a few in pic 2 are drying out pretty quickly.

All the other oysters seem to grow just fine, white, pink, these guys just dont want to grow. I should add theyre grown on rye/popcorn before inoculating into straw (12pH) and cased with coco coir and then soaked in 12 pH water before casing.

It's been a few years since I've grown eryngii but if I remember right this is the normal look of pins. This is a good time to keep humidity up and have plenty of fresh air. The temps really matter most for pinning, too high and they won't pin.

Try without a casing next time and to increase pinning keep them in a plastic bag or tote with ge but not fae until pins form and reach about 1/4" in length

Is that a milk crate filled with straw? Well done
