You can sometimes find house plants in hydroleca in garden centres. If
you can find such a plant which is well past its best, you could ask the
GC if they will let you have it to try the hydroleca as a pond plant
medium. They might even have an area of plants awaiting disposal which
are in hydroleca, and you could get a potful for free.




That would be a good idea, Jeff, if Bob hadn't just helped me scupper
the whole idea! Thanks for the thought, though. I have done successful
scrounging in gcs/nurseries before, so I know it can be worthwhile. No
harm in asking.
