The HC hasn't taken yet so either my light is rubbish or I'm doing something wrong.
I used to struggle with HC, but now find growing it to be relatively easy, provided it is given a good start.
First off, I found it will thrive in a high light tank with CO2, a good substrate (Aqua Soil in my case) and regular ferts.
When I first receive the pots, I sit them in my tank for about three weeks, still potted. This gives the plants time to change from emersed growth to underwater growth. IME, it doesn`t like being planted out before it has the chance to do this.
To plant it, divide it in to as many small plantlets as you can, and avoid planting it in clumps. Bury each plantlet deep in to the substrate, with just a little still showing.
It takes a little while to get going, but it looks great when it starts to carpet.
One other thing I have found is that if you uproot a healthy, thriving plant and replant it elsewhere, it will take a while to get going again.
Patience is the key, Garuf.
