Ron,
I'm just now getting a 16 plant bottle system started. I bought some plants from the nursery and am in the process of washing the roots. My problem is: The planting media in the nursery pots contains many large particles of leaves, and other fairly large particles of wood chips, etc.
It's difficult to get the roots 100% clean, before transplanting in the
grow rocks, because the root system in the plant is like a net, it holds all the larger particles and you can't get them out.
Do you have any suggestion on what to do?
