I just started an expirement with an ascocenda. I took a 6 inch by 7 inch by 5 inch deep plastic basket with holes in the sides, and threaded the asco's roots out some of the holes, then filled around the plant with LECA. There is no water reservoir. but I hope the pellots will hold a bit of water when I dunk the basket in a bucket of water. I'll see how this works and let you know how it turns out. I think as long as the vanda roots will grow, they will push themselves up out of any pot, probably even up out of my baskets!
