As the topic says, I am looking for special cultivation tricks for N. ovata. I do grow a small seedling (out of TC I do believe) since january and the plant has already increased in size but still refuses to pitcher. I do grow it under the same conditions as my other highland Nepenthes with humidity above 80% and temperature drops in the night to 15deg or less. I had to place it in a less brighter spot after showing burnt spots on the leafes under higher light levels. I did not fertilize this plant by now but will soon be forced to start it, because the leafes clearly lack nutrients.
Any tips from anyone growing this species are appreciated!
