Not to worry - all of the usual plants used for this smell equally bad.Applied my first nettle tea today. I ordered the seeds earlier in the season, and I finally had enough to make a half gallon. I can see why the bugs stay away, that stuff smells like horse crap, only worse. It looks like you sprayed green spray paint on your plants though, and there is almost immediate noticeable growth. Good stuff!
Horsetail ferns is also bad with a couple of 'extra' aroma profiles moving around - wow!
