Hi Pedro, welcome back!! It is nice to hear from you again. Do you know what type of paphs you have? I don't expect that they would do well in soil since the roots cannot get oxygen and will eventually rot as the soil settles around them and compacts. I would put them into a bark mix, but before moving them, could you post a photo to let us see how they look? Maye you have some terrestrial orchid? A cypripedium maybe?
