sure id be happy to contribute what ive learned from my experience with it
generally, in a majority of the plants ive treated with it (just plain old black coffee cooled to room temperature then poured through the roots) the plants have produced much larger, thicker and healthier leaves, as well as all around more robust growth, i believe you would have similar results with max-sea or a few of the other orchid ferts out there, the only orchid fert ive used is Schultz Orchid Food, and it gave some nice results.
For example, my rajah was looking pretty beat up from the previous owner, wasnt growing much...gave it a coffee treatment, now its growing faster than my N. truncata, and is rate up to pace with my N. spectabilis as afar as leaf production, and its no slow poke!
i think the common problem with "slow growing" neps is that they just are not getting the nutrients they require.
So basically, plain black coffee, poured through the roots every couple of months or even every couple of weeks, should in fact, yield in some very nice growth. for a show of just how well it works, check out Doug's post (DVG) on this thread here
