The weather and the soil here in Kona is practical saying the best for Paulownias, so it certainly will turn out to be a successful (profitable) short term operation.
"Intercropping Studies conducted by the International Development Research Center, show that individual 10-year-old Paulownia trees, produced 190 to 233 board feet of volume. After sawing 40% of this into marketable lumber, the grower would be left with 76 to 93 board feet per tree of marketable lumber."
