I water it every 2-4 days, I only just watered it as I took the picture .I water it from the top, untill the water starts coming out the bottom. It is in my room, it gets almost no sunlight, and the temp is around 13c. it stays like that no change. No humidity, and yet its thriving. Growing faster than the one in my kitchen which gets some filtered sunlightsoil looks rather wet, keep it moist not soggy, it reminds me of a rafflesiana. It's probably a lowlander and it needs higher humidity along with little to no drop in night time temperature.
And, is there serveral plants growing in there?
