Some reputable sources I've read recommend misting Helis once or three times a day. I try to spray mine down whenever I think about it but the truth of the matter is that I don't often think about it. I've got some spare parts from another project, though, and was thinking about building a mini sprinkler system for one of my highland shelves.
So what I'm wondering, for the purpose of my design, is this: what is it about misting that's helpful to Helis? Is it the constant input of moisture at the surface of the media? Wetting the leaves to prevent dessication? Foliar uptake of water? My suspicion is that it's specifically the act of topping off the pitchers with fresh water - reducing the amount of work they need to do to keep the pitchers from drying out.
Does anyone have any insights for me? Thanks.
