    It should be just fine. The purpose of either pumice or perlite is to simply provide drainage / aeration for your plants, not to add any particular vital nutrient. I have used either or both in compost mixes with no real difference . . .

    I think it's better than perlite when blended with LFS. In my opinion, perlite is too fine and just clogs the pores. I mix sponge rock, with pieces ranging 1/4" to 1/2", and LFS and think it works better and is an airier blend.

    Yup, pumice is good stuff. I prefer it to perlite in all of my mixes. Keeps pots grounded, but not overly hefty; it doesn't have that nasty tendency to float to the top of a mix after the first rain; it's less compressible.

    yay, pumice. I've used it successfully with everything from Cephs and Neps to Utrics and Pings.

    hehe.........

    I like how the bag says "organic" pumice.......

    Ya know, as apposed to all the heavily man-made fertilized pumice grown on factory farms........
