If it was being used outdoors in a larger scale agricultural venture i wouldn't feel uncomfortable with the idea but of course it would be an additive to a nutrient of some kind, but indoors doesn't sit right. In saying that Redz has a tip top soil full of life so chances of any bad pathogens running about would be slim. Don't think this would be a great idea with just plain old potting mix. I had thought his plant might get all moody and sulky and give him grief now though.
