The two journals I'm currently keeping show quite clearly how important good lights are. This plant here is a week older, but has grown considerably less. Whilst the height is about the same, fewer leaves have developed here and they are also smaller.
I have now moved the plant a little closer to the window, as the electric plant light is only just enough to prevent it from becoming spindly.
