| I grow mostly Paphs and find commercial mixes unsuitable. I have to doctor them up. I have successfully used commercial mixes straight out of the bag for Cymbidiums and Cattleyas though. I think the thing I dislike most about commercial mixes is that the bags are usually opaque and you can never be 100% certain what you're getting. I once bought a commercial mix, took it home and opened it only to discover lumps of clay in it. Not the expanded clay pellets, but lumps of clay out of the ground. |
