First of all, I apologise for any potential mistake in my English since it is not my native language.
I have recently established a sphere riparium which is approximately 40 Litre (10 Gallons). I am using Fluval 106 canister filter and DIY pendant light comprised of COB Led with 35 watt power. Above water section, some indoor plants such as Peace Lily, Syngonium and a kind of Maranta species were placed via planters.
No substrate is used, roots are free. Underwater section, there are mostly Anubias species. I would be pleased if you comment. Thank you for your interest and time.
