Chan Chan

“Chan Chan” is a clone associated with the Karel Knize collection number KK339, which is classified as a *Trichocereus pachanoi*. The provided community discussion does not contain specific morphological details regarding rib count, spine length, spine color, or epidermis color. Historically, KK339 is associated with Ecuadorian *T. pachanoi* phenotypes, but physical characteristics can vary due to the nature of Knize's seed distribution.

The clone originates from Chan Chan, Ecuador, and was originally collected and distributed by the Czech plant collector Karel Knize under the designation KK339.

There is significant community discussion regarding the origin and consistency of this clone. Rather than representing a single vegetative clone, Knize's collection numbers often referred to broad geographic collection areas or seed lots. Consequently, plants grown from KK339 seed may exhibit significant phenotypic variation, and some seeds distributed under this number have reportedly produced plants inconsistent with the *T. pachanoi* description.

No specific cultivation requirements for “Chan Chan” were detailed in the discussion. Standard cultivation practices for Ecuadorian *Trichocereus pachanoi* are recommended: * Substrate: Use a highly porous, well-draining soil mix (typically 50% organic matter and 50% inorganic grit such as pumice, perlite, or gravel). * Watering: Water deeply during the active growing season (spring through autumn), allowing the soil to dry out completely between waterings. Suspend watering during winter dormancy. * Exposure: Provide bright, filtered light or full morning sun. Protect from intense afternoon sun in hot climates to prevent sunburn. * Temperature: Protect from hard freezes; keep dry if temperatures drop near freezing.
