    What can be used as a substitute for Perlite and Sphagnum as a growing medium?

    I take it by that, Miraflores, you mean in pots and containers? I rarely use either unless I have a specific plant that needs it as a growing mediu. I normally use 5 parts General Purpose (Peat added) Compost, 3 parts coarse sand, and two parts grit...........works for me:dunno::heehee:

      Perlite is used as a water retentive and aerater. Have you thought about using coir? There are many alternatives. What do you wish to grow?

            IMHO Perlite is great for some cuttings - they take very quickly in it. I used to use it in pots but found that it ended up near the surface and then washed off. Now I use grit - very cheap. I do use expanded white volcanic rock (like perlite but much bigger and heavier) as part of my orchid compost though.

                Also depends on what you are growing ?
                Sphagnum is often used in things like orchids where moisture retention is required.
