Some great advice on choosing a healthy plant
I think it's important to take some other stuff into consideration...
What type of light does the plant prefer? Can you provide that light?
What temperatures does the plant need to grow and bloom? Can you do it?
What size will the plant be when fully grown? Also take into consideration, the length of the spike when it's going to bloom. If you have a tank, yes it might fit a small to medium sized plant but will it fit a 2 ft spike full of blooms?
Will you grow it mounted or potted? What kind of time do you have available to care for them? Mounted plants take more care because they need to be watered/misted more often than a potted plant.
Well, those are the questions I came up with...who else can contribute?
