Hello Everybody, I am starting a series of threads of general culture topics on that interest me and that I think most people would love to learn more about. I was wondering what all of you use to grow your orchids in and why. What do you use for what genera? What has worked and what hasn't? What grades and particle size? What suppliers have the best and most affordable products? There is so much to choose from; fir bark, Orchiata, charcoal, tree fern fiber or chunks, sphagnum or peat moss, coconut husk chunks or fiber, wine corks, LECA, rock wool, synthetics like Hygrolon, Aquamat or Epiweb, perlite, limestone, granite, lava rock,any mixture there of or something else entirely. I am currently using approximately 70/30 sphag/bark for my bulbos, 50/50 sphag/bark for my Brassia, 50/50 bark/river rock for my lithophytic Dendros and pure sphag for my other Dendros and my pleurothallids, chicken finisher(limestone pea gravel) with a little lava rock for my rupicolous Laelia, and bark mix with or without some sphag and/or perlite for everything else. I have tried semi-hydro with LECA with an Encyclia but it didn't thrive so I put it in bark/sphag/perlite.
