I realize this thread is really old, but i was just searching up info on using coffee grounds as fertilizer. I work at a coffeehouse and I know used grounds are great as fertilizer, because I sometimes give my parents a big 5 lb bag of used espresso grounds and apparently their garden loves it. Our coffee is organic, so theres no worries there (it's also direct trade, for any of those hippies out there interested in that kind of shit

). Anyways, I'm in flowering outside in the ground right now. i'm just wondering what the verdict is... coffee grinds good or bad for chron plants? So far I'm getting very mixed messages. Also, for which stage of growth should i use it? If it's full of nitrogen i'm assuming veg. But if it's good for use in flowering i wouldnt mind giving it a try. Maybe I could mix it with the flowering nutes i just picked up. I'm also wondering if using coffee as a fertilizer would affect the taste. Perhaps I'll give it a try on one of my plants
