Mike & PhalPal -- The left-over coir got moldy due to not drying quick enough.
That's why I'm afraid to soak the whole brick. I'll have to cut my brick into squares next time around. Any left-over should be small enough that it will dry quicker.
Mike -- Try it. Just make sure you put a little more perlite (or dynarock) for more aeration. Water when coir mix is almost dry. Like you, I use clear pots and find it easy to tell when to water.
