It sounds like a contam. If it is, get it out and don't breath the shit.

congradulations.. unless you describe how the small ones were grown no one can guess why they are small.

Cakes are a different story. My first ever cakes went damn near 4 flushes (6 weeks) and never showed any signs of contams. I pitched them to be replaced with fresh cakes.

Ever since then every cake has died a green death after the second flush. Very frustrating. I've done everything my little brain can think of to be a sterile as possible, just seems that the green monster found my address and now he won't leave!

OH well, 2 flushes from 9 cakes still gets me little more than an oz dried, which more than satisfies my needs

Peace

There is no need to have casings in near 100% hummidity. Actually it does more harm than good. Over hummidified casing tend to have tall skinny mushrooms that twist and bend as they grow. Not to mention the contams that thrive in a overly hummid enviroment. Casings pull most all the moisture they need internally and not from the air. Most people would think exposing they're casing to un-sterile air is asking for contamination. Its actually the exact opposite.

As for retaining moisture with the top off your terrarium, just mist a few pumps when the casing surface looks dry(usually 2-3x a day). Even when your casings look dry, underneath its actually the perfect moisture.

The Lizard,

Please correct me if I'm wrong but it's rarely 90% humditiy all day long...maybe if it rains but thats if its all day.

On average, I think it's between 60% and 80% humidtiy around here. I know alot of teks don't get very specific on what the humidity should be. Hmmmmmmmm I think it's time to re-evaluate a few things that I do when it comes to casing:-) Thanks Lizard King!

phrozendata, do you case? If so whats the humidity level you keep your mushrooms at?

Thanks again
