Brett..I can use anything from a one inch cube on up! ...so don't fret size! (But customs might reject anything with bark on it or little holes...bug problems)Yes...chunks are better, though. (I have even turned good stuff from the outer layers of some Palm trees!)

Fortunato...around here, naughty boys are in charge..*grin*...bad HUSBANDS get beaten! (family in joke for 15-20 years)

(I sure am littering this thread with extraneous stuff...maybe we better PM the side issues!)
