Going to try S/H outside

[Ray]

Just a caveat here: there are enough plant-to-plant variations, especially with hybrids, even if they are mericlones, that differences observed in such a small test population might have nothing to do with the medium! (Not to mention that there are a LOT more interactive variables at work in orchid growing.)

However, this may be a good way for you to experiment and find the medium formulation that is easiest for you to work with.
