Hi I noticed in the all the Leca. I have never used this media before. It looks like from your photos your not using semi hydroponic because of the slits in all the pots. I am i wrong? How often are you watering your orchids? I have seen this media a lot lately and have wanted to try it. But just not quite sure.... How much water dose it really retain? I have a lot of phals iv been wanting to try it on. Because I have had a few root rots lately. Could you tell me a little about your setup? Thanks sky
