I've just made some DIY-substrate with fert. in it!
It's made from 1 kg. clay (the red kind - with more Fe in it, than the blue kind of clay), 1 l. spagnum soil (dunno what the English term is) without fert., 8 gr. rexolin dissolved in 500 ml. water... After it's dry (I made it like small cubes 10x10x1) You can place it under your gravel... Works like a charm
I'm surprised how effective it is!
Can't say if it's because it's more anaerob or what... But it made a difference for my plants!
