Interaction between light, humidity, and temperature
So when we adjust One parameter, it obviously has a knock on effect with the others. I'm asking this related question in regards, Specifically, to my B little stars; but general answers will be helpful for me and others as well, I'm sure.
For e.g., I was keeping my roots at 77*F during the day, via seedling heat mat; off at night brings temp down to my room temp of 73*F. My humidity was ranging between 55-61 (higher if raining outside). My lighting was recently upgraded and I have been gradually lowering lamp to increase fc slowly to max of around 25-3,000 just above orchid; have a bit more to lower, as have been lowering every 3 days or so...making sure no signs of burn or stress on leaves. Also note that light is a cfl bulb and puts out little heat, which I normally (based on hermit crab and betta/fish care) wouldn't expect to alter the humidity that much.
As my humidity drops though, esp as it will in Winter with heat on, an added humidity tray adds about 5+% to baseline. But it Also drops my root temp, even with the heat mat, down to 75*F.
Since my B little stars is very young, and the roots are only now getting close to going into the media (all Original roots were dead)...which is Most important at this point?
Humidity (if so, best range)?
Temp (or is as low as 72-75 still acceptable)? And speaking of temps...what do orchids respond to, actually? Root temp or Leaf temp, or Both? Anyone have any links to any reasearch papers on this sort of thing?
Any info is greatly appreciated, and if anything I'm doing looks too far off let me know (with the Reasons why, please).
Thanks 🌞
