Fertz for emersed setup
I'm setting up a new emersed setup with some eco complete. I read on Ghazanfar Ghori's website that Claus Kettner uses what appears to be miracle grow to fertilize the water column in his emersed setup. What miracle grow (NPK) is typically used?
I'm looking to buy a complete macro micro mix, not to use powdered fertz or make the mixture myself.
