    Nice variation in leaf patterns and colour.. I find dayanum to be impossible to grow well in the lowlands, unless you cool it. They seem to need cooling at night to even grow, not just flower. Otherwise the new leaves will bleach, and become yellow.

    Looks good but you can see that the new leaf is lighter in colour than the older leaves. Perhaps due to sunlight, heat stress or nutrition, but I have observed that in healthy paphs (specimen plants at shows), the new leaf is never lighter colour than older ones. Usually if that happens, there is a problem somewhere. I saw this commonly happen with some of the 'barbatum' (actually some noID hybrid) sold locally which is potted in a mix of fern root + sphag. When I repotted them into my usual mix which does not contain fern root, leaf bleaching occurred quite fast and took the plant many months to adjust to the new media.
