Buce Box (How to easily propagate Bucephalandra and other emersed plants)

James Wong uses Bonsai soil for his terrariums, I wonder if this would be a good medium for this sort of thing.

Would ambient temp at about 18-19 degrees be sufficient to promote growth?

I think Bonsai soil is mostly Akadama, which is moler clay. So it would be suitable and would provide the high cation exchange capacity would be beneficial. Some cat litter is also moler clay so could be an option.
I've used cat litter in my tanks and I was planning to try a similar buce/crypt growing setup using cat litter in small pots.

Would ambient temp at about 18-19 degrees be sufficient to promote growth?

I think temp would be fine. The main concern is keeping humidity high while at the same time ensuring enough air circulation so that things don't become stagnant and mould becomes a problem.
