Metal Halide lights for orchids?
Yeah, a few friends who grow way too many plants (is that possible?)
have Metal Halide/hps lights in areas where we congregate, and the
lights give a harsh cast to things- it seems to bother the non-plant
folks more than most.... Did you notice an improvement with the extra
HPS light? I'm thinking about one of those expensive MH lights with
extra red spectrum. Opinions?
thanks
