I had a smell problem outdoors. You could smell them on the trail that was about 40 feet away, and about 15 feet higher. It smelled really good, and then one day it didn't smell at all unless i was right at the grow spot. The only thing that had changed was I didn't use fertilizer on the last watering. I'm using top soil and a bit of super soil at the bottom, so maybe it was all the extra nutrients? Anyway, they aren't showing any signs of deficiency after 4 weeks of feeding only transplant and seed starter fertilizer, and don't smell either.
