So here's the thing, this tek is not a "maximum" yielding tek like cybs. I found the average yield to be around 1%-1.5%. But keep in mind, this is likely due to the dry tek style, and no heat during pulls.
You can use the microwave technique on a wet tek. It works.
Another thing, Ca (OH)2 has a lower pka than NaOH, so the lime might not as effectively free base all the dmt as efficiently as lye.
Just some things to keep in mind
It's not a bad tek, and it's not the "best" tek. It meets my needs, so I use it.
Sometimes it's good for a change. Other times it isn't.
