Soilless media (commonly used for growing marijuana) was actually a game changer in my apt for indoor plants during the pandemic. If you have any issues with fungus, gnats or any kind of negative root insects soilless media is the way to go. Fertilizers that incorporate beneficial endophytes are also fascinating. However, steer clear of nutrient blends like Noot though - they're watered down and urea derived which is a great way to stress and kill your house plants.
