I got myself 3 miniorchids at IKEA a little bit than a month ago and could see, they weren't in the best growing substrate.  In fact it was rather dense, which doesn't suit epiphyts at all as they like to have airflow around their aerial roots. The roots of one were already rotten and it had to go to the "orchid hospital" after removing everything that was dead. I hope it'll recover and get new aerial roots soon. The two others got new, handmade pots I designed and crafted for them. The pots are made from coconut shells and rope. I quite like the outcome and hope the orchids will use the opportunity to grow their roots through the holes.
