Yes, pitchers is the correct name I think.

I use a mixture of ordinary soil, coconut soil and bark. Ordinary soil and coconut soil because when I bought these this was the kind of soil they were in. Orchid soil (bark) because I read in the internet that you should do that. I have these in double pots, the inner one is plastic one and the outer one is glazed clay pot and there's always some water on the bottom of the outer pot where the plastic pot is on top of rocks so that the soil isn't all wet, just moist. The last layer of soil is bark because it's nicer looking than just ordinary soil. I also have separate water pots around the plants for extra humidity.

I saw an YouTube video that said that it's nearly impossible to get the Nepenthes to thrive because mostly the dry air indoors, so one should keep these in terrarium but I don't have enough space for one so I used every brain cell in my brain 😁 to think about ways to keep the air around the Nepenthes humid enough and I think I've succeeded in that. I've even put short macrame cords from the clay pot water to the bark on top (capillary action) for possible extra humidity. (I've cleaned enough times the floor from water after one of my cats dragged it's catch, a woolly sock to her water bowl and the sock gets all wet and the water magically shifts from the water bowl all over the floor to know that capillary action should work for my benefit too, not just to make me clean the floors more often.)

I've never tried to grow orchids though, I hear they are even more demanding. Even reading the instructions on how to take care of orchids makes me exhausted.

Don't worry about the late reply, I usually am a late replier so no worries. :)
