I'm pretty excited to give this a go (hopefully soon). I've found some pretty good layout ideas online and have a pretty good idea of what I want to do. So if I I know I already asked this but how often would I have to change the substrate with a false bottom? Would it be feasible to plant the plants directly in the substrate or should I stick with pots? I also have seen some pretty cool set ups with pots attached higher up for pothos and other vined plants. Is this a complicated process to create something like that?
