What are PPM's?

[Ruff Ruffman]

Can someone please tell me or point me to a link or thread that will describe PPM in deinition and in practice growing? I am a soil grower growing and 80/20 indica, pretty fast flowerer. Thanks for any responses.

ppm is part per million....its about the concentration of the nutes......
