Is additional mineral fertilization required if I already use CO2?
Do I additionally have to use mineral fertilizer even if I already have a CO2 system?
CO2 does not replace the minerals and trace elements, but the plants require both. Mineral fertilization (e.g. with sera florena and sera florenette A) is thus not only necessary, it possibly even needs to be intensified because of better growth due to CO2 fertilization!
