The following info about this strain was posted by John Allen at the entheogen.com forum!
The Allen strain was developed by Hydorogen of the Shroomery in honor of my research and spore print gathering.
Another one he developed was the Elephant Gate Strain. I did not name either one of those although they are from Koh Samui. The Allen strain I cannot recall what area it is from. I did not name it. But I understand it too is a fast colonizer like the BHT and the Cambodian Cubes.
