Wood ash can also be used in place of hydrated lime as it will also increase the pH to 12-13.

According to Aloha Medicinals pH swing pasteurization leads to better yields vs steam pasteurization with wood ash being the most efficient. Here's a PDF they put together with some more info: http://www.alohaculturebank.com/mushroom-growing.pdf

Or there site also talks about lime pasteurization: http://www.alohaculturebank.com/low-tech-growing.html#.Vyl1kyNlDqA

Wood ash has contributions to nutritional yield. I suspect ammonium hydroxide may help too in small amounts by supplying more nitrogen in substrates that are not "hot" to begin with

Lime and bleach works fine for all mushrooms. Also profit wise ostyers are easier to sell in my market i get 9 dallors a lb vs 7 for others. Not to burst your hard labor or anything but you need to be sure you want to do this for a living owning a small company where your the owner and only worker is an ungodly amount of paper work and fees i was paying 15k a year to feds just for the right to run a mushroom farm. The key is to produce less then 2000 lbs a. Year in this state. Good luck

Never realised lime could be organic, always thought it would be considered as a chemical thus removing any chance of organic labeling.

that would be a little unsettling thinking of organic milk, orange juice, beer, etc... factories not being able to sanitize their tanks etc...

To be eligible for an “Organic” label claim, a product must contain less than 5% of materials found on the National List.
    To be eligible for a “Made with Organic (specific foods or food groups)” label claim, a product must contain less than 30% non-agricultural materials included on 205.605(the national list) and any non-organic agricultural ingredient. 205.606 does not apply to products in this label category.

There are a few sanitizing agents listed specifically on 205.605(the national list) as allowed for cleaning of equipment and/or direct food contact. Chlorine, peroxyacetic acid, hydrogen peroxide and ozone are a few with particular annotations.

Certified Organic growers are not allowed by the USDA Organic Rules to use either burnt-lime or hydrated-lime

There are two basic types of lime available:

-Calcium Carbonate, called calcitic limestone (CaCO3)

-Calcium Magnesium Carbonate, called dolomitic limestone [CaMg(CO3)2].

If calcium carbonate is heated, the carbon dioxide portion escapes and the result is called burnt-lime or quick-lime (CaO). If the burnt-lime is combined with water, hydrated-lime [Ca(OH)2] or slaked-lime is produced.

So the trick is to use less than 5% of the substrates weight? Or since the mushrooms themselves will not have the lime it doesn't matter?

Yeah, they break everything down anyway. Or at least they suspect they do.

I was reading Stamet's article where he compares oil contaminated soil treatment. Aside from being the best possible method for cleaning the soil from oil, he says the mushrooms should not be "tainted" by the oil AFAIK even though they say that one should not eat such mushrooms(sounds like something a lawyer would make you write anyway). The interesting thing is that the spores created from such mushrooms will be able to fruit better next time round.

Why? Don't you believe it? I don't consider him as a mentor, the way overpriced items he sells makes that rather impossible but I do believe that it is a very good way to clean up contaminated soil. I didn't really read all the article but I saw him on a recording of ted talks or whatever it was and he was saying how tests were done and was even talking in numbers and shit that I didn't understand but everyone there was like  :amusedapplause:


I think even RR made some work with cleaning up drainage contaminations with mushroom mycelium but I might have him confused with more of stamet's work.

Staments has a history of exaggerated claims, unsupported theories. Etc... Good with a grain of salt. He isn't dumb, he's just like the Billy Mays of mushrooms

He is anything but dumb, a $10 scalpel is sold for $20 on his site. The difference? One is named scalpel #7 on ebay while the other is named "Stamets favourite scalpel" on his site. Yay! Honey, look! I just got buttfucked into buying a scalpel Paul Stamets likes. There is nothing dumb about raping someone's wallet and making them happy in the process.
