On a show called Get Up and Grow.

It was almost a complete waste of time and the host was left very unimpressed.

No mention of curing.

And the person doing the demo actually said that adding sand made Tufa WEAKER!

Her recipe was OK.

2 Portland

3 Peat

3 Perlite.

But her finished product was beyond rustic and she didn't appear to have much interest in the hobby at all.

I like rough tufa but prefer it to be reasonably symmetrical.

This tutorial was not likely to attract very many new fans to our hobby. Very disapointing.
