Ok total newbie here with limited plant knowledge so be patient with me and my silly questions. I have just purchased a Fluval Roma 125 and would like to have it planted. I currently have a 60 litre cube with 5 amazon sword plants ( 4 in pots and one runner) few crypts and a big anubais which is doing quite well floating near the surface. They are just in normal gravel and get fed plant food once a week i have no special lighting and they seem to be thriving. Hoping to transfer plants into new tank. Am i best to just keep doing a weekly feed or is there any other method eg substrate that can go under gravel which can hep them grow better. Looked at CO2 units and far to complex and expensive for me. Thanks for reading
