I have swords growing in gravel only - both the fine, natural gravel and
the course stuff sold in 5 lb. bags at the pet shop. Although I'm sure
they're not doing as well as they could under optimum conditions, they
look good and grow pretty vigorously. There was some leaf-yellowing but
that's stopped since I began adding an iron-intensive fertilizer.
The water here varies between 14 dGH and 20 dGH (depending on the "supply
of the day" and the pH averages 8.5. Java ferns grow like weeds.
