The effects on nepenthes as well as other plants are pretty astounding. It's definitely worth checking out Big Bella's thread here: http://www.terraforums.com/forums/sh...Roast-Pressure
I too, use the 16-16-16 MaxSea once a month, and the coffee once a month two weeks after the MaxSea. So my plants get "dosed" bi-weekly. Most of the plant's I've fed coffee too, will produce the next leaf about 3 times larger than the last.
