Vertical farming meets bamboo bike building (and other applications that need REALLY straight bamboo).
The most difficult part of building the frame was to find quality bamboo rods. It took me much more time than the building itself. I visited several dealers in near surroundings and I tried to find appropriate rods of the necessary diameters from huge amount of bamboo. Finally I found a few rods I wanted, but frankly said, next time I build such a frame, I'll rather grow my own bamboo or fly to Asia for it. -- BME - Brano Meres
