Philos air layer great, just find a bare peice of trunk and place some peat moss around the trunk, wrap in plastic or fabric and keep it moist, it take some time, philos don't grow that fast...works like a charm for me...
My pp was a broken branch I picked up of the GH floor, it took bout 2 months to root, I used 30% sand 70% peat...it's color is terrible now...
