Excerpts from The Encyclopedia of Psychoactive Plants
The cacti can be grown from its tiny seeds or propagated from cuttings. The latter approach requires simply placing a piece of the cactus in the ground. One or two new stalks will grow from the place where the cactus was cut.

Family
Cactaceae (Cactus Family); Cereus Subdivision
The almost spineless columnar cactus can grow as tall as 6 meters (Britton and Rose 1963, 2:134 ff.*). It has several ribs—usually six, but often seven or eight, sometimes as many as twelve, and in very rare cases (or not at all?) only four (the Indians consider a four-ribbed cactus to be especially powerful, as it symbolizes the four cardinal points). The beautiful white flowers appear only at night. The very delicious red fruits, which are almost the size of a child’s head, only very rarely develop.
With regular watering (daily!), one can almost watch the cactus shoot up from the ground. At the same time, it is modest in its needs and can survive for months without water. Pieces cut from the cactus can survive for months or even years and can develop lateral shoots even without food and water. Anyone who plants this cactus at home will be impressed with its unbelievable vitality.
