Diatomaceous earth is not toxic, but would make the mushrooms gritty, which you don't want. This has nothing to do with what makes a product organic. I believe the use of compounds like methyl bromide (a soil sterilant that is applied before crops are sown and is then allowed to dissipate) prevents a crop from being certified organic even though it never touches the plant. Otherwise organic strawberry farmers pretty much couldn't afford not to use it, but the internet tells me they don't.
The list of allowed non-agricultural food ingredients is not directly relevant (except as a separate sign that diatomaceous earth is quite safe); what matters is the list of pesticides that the organic certification people allow. I don't have a complete list, but they definitely allow sulfur, nicotine, pyrethrins, and copper, and I'd be very surprised if diatomaceous earth weren't also OK.

I said around the greenhouse, as in a ground perimeter. Indeed it would not effect the 'organicness' of the product.
That said, OMRI lists it as an approved crop pesticide, food additive and parasiticide.

That kinda depends on the auditor. Some say residual droplets will migrate in the air if sprayed when product is in the vicinity. In organic agriculture, they do not allow non-organic pesticides and herbicides even though they do not touch the product. best to consult your registering agent before proceeding.

Use food grade diatomaceous earth which is amorphous silica. If slugs and snails are problematic you can always use saucers of beer which catches lots of gnats, too. Even copper wire or pennies placed outside of a threshold or around a grow will deter mollusks.

De is only effective when it is dry which makes it pretty useless in a grow room environment. Beer is a bad idea as well because it attracts every critter known to man. Use iron phosphate to control slugs. Omri approved for organic control.

True, I was suggesting DE for outdoors around enclosures like GHs, tents or logs and such. I use beer around my garden, but phosphate sounds like a better idea than throwing a party for critters..lol

I love me a critter party!
By the way, I have used DE in my garden in washington for years. It works great whether it's moist or not. The trick is to use a lot.
Even when it's wet the slugs and snails avoid it, and when it dries back out it works even better. I'm not sure how wet your greenhouse is, inside or out, but if it's so wet that DE is rendered ineffective, you should work on moisture control haha.
Give it a try, I don't know if you can find it cheap right now, but just before spring I can get it at the local hardware store for pretty cheap.

hey how's the pinks and yellows size wise compared with say pearl and blue? I'm noticing noticably smaller clusters on the pinks, maybe 1/4lb max, where as 1/2-1lb normally for blues. I did not get humidty running until after they were pinning, it's unclear if that inhibited them. I'm also playing with poking more holes in the straw logs.

^^ I don't have the experience AV does, but all my pinks grew smaller, and in smaller clusters than blues and pearls I've grown.

Not only are the fruit bodies smaller but also thinner. ESP in yellows. This makes them very delicate with poor shelf life. Why you rarely (never) see them sold at grocery stores. It also makes them lighter. Charge more money for them.
