Another interesting idea using lime and sawdust:

If you measure exactly the amount of lime water needed for ~60% hydration rate you will have no excess lime water to dispose of.

Sodium percarbonate (oxy clean) also works great on straw for oysters and cubes,    without environmental risk of dramatically changing the ph of soil.

Glad I could share it, but bodhisatta has a good point about needing to neutralize it. I think that there's a bunch of work needed in order to be able to recommend the hydrated lime (calcium hydroxide) path to any cultivator.

1. How best to neutralize it (CO2 + CaOH => Calcium carbonate, or calcium acetate with vinegar, for example)
2. Best to point out that solubility is *lower* at high temperatures. Go with cold water.
3. Show that it can work for species other than Pleurotus... (Working on it...)
