process of washing the roots
 

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?

As long as the particles won't dislodge from the roots then it is ok to leave them. It only becomes a problem when particle work there way through your system and clog your pump.
