I`ve used it with JD seed meters and it worked good. With a air planter I`ve used Cell Tech liquid or Vault hp, only used liquid with the air planter. A friend with a White planter uses liquids, with good luck. Gotta stir it up good and not put on more than recommended. The Graph-ex, I think takes care of the need to use graphite on the meters, if I`m right then don`t use the graphite in addition.
