We grow a species named Guadua Angustifolia on our farm in the tropics. We have used in for a guest home, three sheds for our animals and a
fence line that is 90m in length.
I believe in matured in 5 or 6 years and the height was close to 20m high and width about 10cm. We have 7 clumps of it and harvest one or two a year. A great building material.
Also we have another species that we can harvest to eat. I forget the name off hand. We use it to
feed our pigs as they seem to like it a lot.
We have around 8m to 10m of rain a year and I believe most species like lots of rain for fast growth.
