Subject: tufa containers


A friend and myself have been making tufa containers the past two days
they are a lot of fun....our receipe is   equal parts of peat moss,
vermiculite,perlite, portland concrete, and water to make it stick
together, you don't want it to wet just so it will hold together...we
choose the container we want to use as a form, cover it with plastic wrap
and proceed to  cover our form with the mixture....it should be about 2"
thick all over...when you are done you cover it with a wet towel and
plastic and let it sit over night...the next day remove the form you used
and we use a wire brush to expose the aggrigates...then cover again with
wet towel and let sit for another 24 hours  then uncover and sit your pot
in a cool place out of the sun so it can cure for a couple of weeks...you
might want to wash it out with a solution of vinegar and water to
neutralize the concrete before you plant in it...good luck!
