I found a picture on Instagram of a woman in my country having an Arachnis flos-aeris and she said that this orchid practically grows like a weed in the town she lives. Perhaps the cutting I have is an Arachnis flos-aeris, but I'm only speculating. I guess I'll just have to wait until either of both plants (my cutting or the parent plant) blooms. Either way, from what I read both types (Renanthera or Arachnis) needs a lot of sunlight which is not a problem in my country and high levels of humidity. Now that it's actively growing I'll concentrate in providing fertilizer and water.
