just curious as to everyone elses soil mixes as their are probably a lot of different recipes. I personally like to buy the pre-made orchid mixes and then modify them a bit. I usually add a bit of lava rock for good drainage, I add perlite, a bit of peat moss, some wood chips, and large grade orchid bark. Of coarse the recipes vary depending on the species of orchid I am potting up. I have found the lava rock to be especially beneficial in keeping the soil mix well drained.
