I have noticed a few orchid nurseries here in the UK sell silicate solutions and clay powder containing available silicates ... the promotion suggests it strengthens the plant tissues. I know that some grasses incorporate silicates, but do paphs? The reason I'm asking this follows that fact that Slipperfan reported success with diatomite mix and P. hookerae. Firstly, diatomite contains and will release small amounts of silicate. Secondly, P. hookerae and P. volonteanum are (as far as I can gather) often found near serpentine rocks which also can release silicates. Very, very, speculative, I know ... can any of you shine a light on this?
