While I am asking question I have some about my epidendrums. I have a Nocturnum, diffusum, and ciliare on the top shelf of my box. I am wondering if the Nocturnum would like less light. To give a comparison I know the Diffusum is happy cuz it is in spike and growing well. THe nocturnum looks like it could be a little dark, but I know epi's get some purplr on them. Does anyone have any suggestions?
