    Granite is extreamly inert and composed of quartz (silicon dioxide) and feldspar. I doubt anything would be released to the plants. At most a little potassium or calcium might come off the feldspar portion. I am sure it plays a larger role of improving drainage and keeping the soil from compacting. Personally I prefer something that will do the same and is also porous. Pumice, perlite, lava rock etc. They will add similar benefits but also hold air which the roots like and water in reserve (little sponges) which helps balance soil moisture.

    edit:
    oops meant to answer the original question also.

    I use a peat base mix for N. bicalcarata. Primarily peat some silica sand and a little coconut husk chips although fine fir bark would work also. Pure LFS stays too wet in my situation with nearly daily overhead watering.



    Is that a Nepenthes in your pocket or you just happy to see me?

    That is a big point, Tony. I know one Aussie grower that uses 75% pine park, 20% perlite and 5% peat. That is too course for me, and the big difference is he has auto-watering several times a day coming on. I think mucho drainage with watering like that must allow a heck of a root system to develop, but I am far too lazy to water like that, and that much RO water would be too expensive anyway.

    Regards,

    I guess I should have described my growing conditions a little better. My bical will be hanging outside underneath an aluminum awning so I will be able to control water. It is on the south side of my home so it will only get direct sun until 11:00 AM but will be in bright light all day. I live near the ocean and it will be exposed to our constant on shore breeze.
    Sooo, under these conditions, would pure LFS be the way to go? And should there be anything in the bottom for drainage? If so will cypress mulch work?

    I still wanna' know what the heck "orchid bark" is.

    Lauderdale,
    Orchid Bark is what orchids are usually grown in. It it bark of a suitable type of tree in different sized pieces. This is ideal for orchids, because they typically require a very well drained medium. I hope that helps!!

    Should there be any kind of bark at the bottom if I go with pure LFS?

    Lauderdale,
    As long as you control the water input, it shouldn't be neccessary... GOOD LUCK!!
