Good morning all, Currently on my new setup i have used sand as the substrate but without any soil/ fertiliser under it.
Currently injecting CO2 pressurized and dosing with Ferts, but plant growth is not really happening. Could this be because of the dense sand preventing nutrients getting into the roots ???
If so does this mean buy some soil and rescape to get round this ????
