Sorry! You should NOT feed skimmer waste to any plants!! The salt content will kill them. No, I have not tried this, but I have a BS degree in Horticulture and Plant Pathology and am quite sure that this would be the result. Very, very few plants can tolerate any salt. I think that this subject did come up on a previous thread and someone had tried to give this to a plant and it died. If not for the salt I think it would be good.
