    I used pure peat for nearly everything for a couple of years. But since I like to keep everything very wet, I had problems with anaerobic decomposition (sour soil) which helped me to lose a few plants.

    Presently I'm also using a vertical layering technique, and have been for several years now, this technique has helped eliminate the problem of sour soil (anaerobic activity). I vary the exact procedure depending on the genus of CP being planted, and modify how I create the layers in each pot, just to avoid being too monotonous. It seems to suffice just to have a vertical layer of entirely porous mineral matter. With this technique, I often create two layers of porous mineral such as perlite, pumice, vermiculite, or various combinations of these and a few other porous mineral ingredients.

    That's really interesting. So, you just have a random sort of "tower" of porous material standing in the pot surrounded by peat? As a substitution for pure peat, I'd think pure shredded LFS would work just fine, right?

    Actually it evolved into a pillar of sphagnum peat surrounded by porous mineral media (pumice). Since then I have taken to doing it as illustrated in this drawing, quick and easy to do. Here is an image to help illustrate the concept. There are many variations of this technique that are possible. I've tried many of them and they all seem to work equally well.



    If you use pumice or perlite for the porous mineral media, it not only increases the aeration of the media, but also reduces the amount of media needed per pot, and lightens the pot as well.

    I'm stupid.

    What's the grit size mean? Does a smaller grit (like 30) mean the grains are larger? Or does a larger grit (like 100) mean it's larger?

    Cool idea Joseph, Thanks for detailing it as I was having a hard time picturing it as you'd described.. looks like I got some re-potting to do

    Joseph, where do you buy your pumice? I had been looking for some for my cacti, but couldn't find any sources.
