I started a new topic (it would be a bit displaced in the N. madagscariensis topic)...
In what conditions do you grow your Nepenthes rajah and how fast does it grow ?
night : 16°C (60F) and ~90% humidity
day : 25°C (77F) and ~ 75% humidity (sometimes humidity drops)
I grow it in a terrarium behind an east facing window (morning sun) and also use artificial light (70W high-pressure sodium light).
Substrat is mostly a orchid-mix with some sand
I have mine now for 10 months and it grew from about 5cm in diameter to about 7cm in diameter (but size didn't increase during the last months)
It has about 3 green leafes and 2 pitchers (2cm) at the same time. It produced several additional plants .I separated 2 of them some months ago but it has 3 new small plantlets now.
would be interesting to hear about other growing conditions and growth rates...
