We use it for it's "low density (providing additional voidage and aeration in the soil), significant adsorption and cation exchange capacity, and the ability to promote living microbiology in the soil"
And we don't use any chemical fertilizers, just top mulch and biochar.
Here's a bunch that we recently harvested, it's from the first dwarf Bluggoe we grew and up until then I had thought all Bluggoe produce small bunches. I was surprised when it weighed in at more than three times the average bunch size of our local USDA Tropical Research Station and they are the comparison we use.
