    Just want to get opinions on this. I know it stores moisture but don't know if there are any negative impacts.

    Hi Dyflam, I have read that vermiculite will eventually break down and release minerals into the soil mix, but I have seen other reports saying it won't, so I don't know for sure. What are you wanting to use it for? Most peat based soils do not have problems with moisture retention and pumice or pearlite tend to work better for loosening soils as they do not compress.

    I use vermiculite in my soil mix about 10% of the mix for years with no problems at all

    I would definetly recommend using vermiculite for the cps that like richer soils(mexican pings/nepenthes).

    I dredged this up because i have an almost unlimited supply of vermiculite (it's used to pack all the chemicals the lab gets in case the bottle breaks). Is the consensus that it's a good additive to lowland mixes in general, and a bad idea for highland? What about drosophyllum or pygmy sundews?
    There's no 'a' in perlite.

    when it breaks down it becomes into this mucky gooey stubtance which is very unpleaseant to see or have also it contains minerals in it such as pottasium and magnesium which make it unsuitable for cps other then nepenthes and mex pings . i use it on my neps and pings and they have no problem .

    I didn't know that mica would break down. How long does that take?
