Philodendron gloriosum is a creeper, the rhizome creeps along the ground and puts down roots along the way. With that in mind, I keep mine a long trough, the results I think speak for themselves: https://i.imgur.com/WP1GrrP.jpg https://i.imgur.com/KcXBXLx.jpg
I started with this smaller bin then when it outgrew it I added 4 inches. Now it's at the end of that one too, I'll let it dangle for a while and then look at chopping it I guess, this thing is already chugging a liter of nutrients a week.
Took me fucking hours to find this thing haha. And now it's nearly outgrown it in only 3 months. https://www.amazon.com/gp/product/B083BBJVDS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
