Interesting JDL. I've only been in bonsai for six years, but I now use 70 - 100% turface for my trees, depending on the species (the rest is composted rice hulls). I do not sift anything...the turface drains well without sifting, even after three of four years in the pot. I have no controlled experiments, but my trees in 100% turface are doing great. I think your horticulture prof is brilliant....brilliant defined as agreeing with me...lol.

Cheers
Brian
