This is in a combination mix. The 8 inch basket has the side walls stuffed with moss to hold the Orchiata/hydroton balls/sponge rock inside. I drop the whole thing into a bucket of irrigation water once or twice a week, let soak for 15 min, an hour or overnight (if I forget about it!) then hang it high in the GH rafters. It can dry out between waterings but not always. I have two clones of schrilliana potted the same way. One plant of harrisoniana, 2 plants of walkeriana and loddigesii potted in the same mix but are in coconut fiber lined metal baskets. All are watered the same way, soaked in a bucket.
