Assessing Dendrobium Latouria-Type Health

[c123anderson]

Hello all! I have a question that I haven't been able to search out an answer for. I would appreciate if there is a site or if anyone has any thoughts.

I received a latouria-type dendrobium about a month ago, specifically a Den. Little Norman. I am enjoying its beauty but am somewhat concerned and not sure if I should be. It seems to be happy and growing, but its pseudobulbs do not have the smooth, full appearance that I have come to expect with my Den. spectabile. They actually are thin at the base (like a kingianum) and wider closer to the leaves.

Conditions: lives indoors w/temps ranging from 68F to 74F. Humidity 40%-70%. Watering about every 4-5 days. In a bark-mix medium. No artificial light (right now). Cloudy daylight through a filtered window at about 8-10 hours.

My question: what should I be looking for as far as measuring plant health with this type of plant?

I usually watch pseudobulbs and leaves for general plant health and try to watch for new root growth, but these pseudobulbs have me a little worried that it's not getting enough water, but the pseudobulbs I wouldn't quite characterize as "shriveled" -- meaning the inconsistent shriveling that I have seen in dendrobium pseudobulbs that are not getting enough water.

Thank you for your thoughts. And, let me add, I've had some great answers to previous questions. I need to post a "happy" post about my orchid successes, which I partly attribute to some great advice I've received on this board, either directly or in answers to others' questions. Thank you!
