    I've had good luck with a mixture of: LFS, fine orchid bark, charcoal, pumice, Hydroton and live LFS. I've noticed more vigorous root growth when I've included the live LFS in the mix.

    I'm using a mix of 1 part each: fine orchid bark, charcoal, perlite, finely shedded dried LFS and Sunleaves brand "Rocks". This is a new growing medium made of fired shale that has expanded and holds water, the bag I have is the small pieces about 1/4 - 1/2" in size. The plants roots and bases themselves are bundled in a handful of live sphagnum moss and then potted so they can start off in the live moss and stretch their roots down as they see fit.

    Anyway the mix is just a modified form of what the local greenhouse sells as "orchid seedling mix #1" (fine bark, perlite and charcoal). I have had this intuition that Neps seem to grow faster / put on their most growth about 2-3 days after a soil flush, so for my new Nepenthes collection I've decided to use a mix that will allow me to flush their pots twice or more a week without fear of them staying sopping wet. I also pot the HL plants in Net pots exclusively so they dry out faster (though ambient humidity in their chamber is 90% and foggy half of the time). We will see how my theory plays out as as my plants grow on, so far they seem to responding well.

    The ideal mix is a light airy inorganix mix that is relatively nutrient free and has medium water retention properties, and among all these things is cheap as well and can be easily found.

    Interesting. I was just contemplating switching over to using netted pots for increased root aeration instead of the solid cheap plastic ones I am currently using...

    JB I use a mix of LFS, some of which shredded by hand and orchid bark.Simple and all seem happy.

    Honestly, I use 1:1 peat : perlite. But I also repot all of my plants every single year. Its like their annual maintenance. I like to keep good hygiene, and it's easier to do while they are unpotted. Rinse off the roots, clip all the dead stuff, give the roots a spray of systemic pesticide for good measure and in they go to fresh media. It takes me a couple days (which I spread over a few weekends,) but it allows me to take good inventory, make sure nobody is neglected, take cuttings, remove basals, etc. I do it in the spring when I repot and divide all my outside plants, which get the same mix. Sometimes I'll put some LFS or orchid bark in the bottom of a Nepenthes pot to promote drainage, but not always.

    Well I put a mix together. Seems to drain fast and hold moisture. Thinking of using it on some orchids too.

    I used what I could easily find.

    1 part each

    Better grow orchid mix
    Medium tree fern fiber
    Lava rocks
    Cedar mulch
    LFS

    Then on the very bottom used a layer of cheap drainage rock. I like the weight it gives to the pots. Especially for the top heavy plants. I will post pics after I get back from the orchid nursery.

    Watch out for earthworms if you plan to put the pots on the ground outside. The first set of nepenthes I got more than 25 years ago were potted in a mix of osmuda and tree fern fibers, and before I moved to PA they had been growing for an entire summer in pots on the "ground" in Florida. They did great until the baby earthworms that had gotten into the pots grew up and chewed the mix into a dense sticky mush. The mix should have lasted much longer than it did, and I wasn't expecting what happened. After I got to Pennsylvania I lost a few plants before I discovered it and repotted. The plants were actually on a low pavement on my porch, where I thought they would be safe. The nearest I can figure is that the earthworms got in during a minor flood from a particularly vicious downpour we had that summer.
