There's a lot of products claiming to contain ormus or orme, so I would spend some time researching a) what the fuzz is all about and b) the seriousness of the distributors, i.e., their links to research-sites, test-trials, etc. As in any other commercial field, the difference between the best and worst are vast. Now, ormus can be easily dismissed as snake oil (and there is a fair share of un-necessary and bogus products out there), but there has been a lot of research on this subject, both in main-stream laboratories and by therapists, eco-growers, individuals and so forth. Admittedly, the science behind isn't exactly, eh, main-stream, so it's easier to accept if you're a vitalist and not an atomist. Then again, there's enough of growers claiming that chemical N-P-K is all a plant needs, which I think is ludicrous.
I replaced Advanced Nutrient's Grandma Enggy's Seaweed Extract with Sea-Crop, that contains high-quality kelp and supposedly ormus. Comes highly recommended from many sources. Just use sound skepticism, I guess...
