Not necessary, Marvin. Nepenthes are humidity lovers. The higher the humidity usually, the more better they grow. For growing highlanders, humidity is one of the MOST important factors. I noticed that my rajah, burbidgeae, maxima and veitchii highlanders didn't really seem to have problems when I forgot to put iced bottles in my HL terrarium set up last time, but one day, when I was testing out my humidity by opening all my terrarium holes.....WHOOSH. Within two days, all my HL neps started to go into suspended growth, with burbidgeae dead first.

I notice though, that lowii is rather picky about temperature. Rajah and maxima can still pitcher under lowland conditions but burbidgeae and veitchii didn't pitcher at all, though they still put out some leaves. Lowii was the first HL nep to die in my terrarium :sad:.

All in all, a HL setup is much more easier if you have high humidity or you can provide it, if you have cooler nights and if you stay in a landed house. Believe me, condos can be very dry and hot during the afternoon.

Lowii first, followed by burbidgeae, followed by rajah, followed by veitchii. My maxima till now, still alive. But stuck in a suspended animation :sad:

Technically speaking, only those setup that utilize somekind of cooling (to maintain below 27C during daytime and achieve minimum 12C or more temperature drop during night time) can be consider as true H/L setup for those H/L nep species and hybrids.

So by only using natural cooling (passive cooling), the most that we can achieve in tropical weather is probably barely close to intermediate level.... Couple this with constant high humidity, it's possible to keep those less finicky H/L neps and most intermediate some what OK but to get it to fluorish (healthy growth, getting nice pitcher to leaves ratio and flowering) is probably very difficult under such condition.

That's my humble view... :shy:

Fauzi once did a HL setup to keep some true ultra HL neps, such as hamata. He simply used styrofoam box with ice bottles.
