What plants can I keep in a biocube 29 with a 36 watt 6500k bulb? I have a banana plant (that is disintegrating, but keeps coming back), moss ball, duckweed, and a cardinal plant (also falling apart). What plants can grow in this and how long do I need to leave the light on for? Thanks, I was thinking some Red Ludwigia and some anubias for a new aquascaped tank. I don't have a co2 system either. I tried plants with dwarf baby tears, red ludwigia, rotala indica, and various other plants and they pretty much all died, no idea why
