OK, I built a trellis for some of our orchids. The trellis is 14' long by
4'6" wide. Unfortunately, it doesn't
hold all my plants, but that's another story. I was going to get a portable
lawn sprinkler, but am considering
installing sprinklers or mister heads on the trellis.

Would love some ideas and advise on this.
My collection consists mostly Vandas with some Oncidiums, Dendrobiums and
just few phals.
