Super Pedro is a very interesting Trichocereus scopulicola cultivar or hybrid involving it! It is closely related to the cultivar Trichocereus cordobensis.
SUPER PEDRO is a very popular clone within the Trichocereus community. I (and many others) originally thought this plant to be some kind of hybrid between Trichocereus pachanoi and Trichocereus scopulicola, but the exact parentage is unknown. It is a hybrid that was grown from a whole lot of unlabeled seeds by Jim Hall from Cactuscountry.com. The whole body and the flower traits point towards it being a form or hybrid involving Trichocereus scopulicola. There are definitely many differences between it and the standard Scop FR991, but you can clearly see the relationship to this species. Friedrich Ritter also collected and sold populations from Tarija that he described as Trichocereus crassicostatus. NMCR also collected a whole lot of seeds that produced versions of Trichocereus scopulicola that clearly differed from Ritter´s main collection. There are very few collections of Trichocereus scopulicola, so it´s either one of those or a hybrid with another parent.
Trichocereus are forgiving plants to grow in the UK. As are most cacti grown in the UK, they are best grown in a greenhouse or conservatory (grow tents are also used for younger plants), South facing is a distinct advantage.
Watering from Spring (April) to the beginning of Autumn (End of September). Depending on what kind of summer we get will depend on how frequently you need to water, but, less is better with cacti. During the winter months, little to no watering is required or the roots could rot (they do not like to be wet for long periods).
In warmer climates, you could go for a more nutrient-rich mixture (50% organic / 50% inorganic). But, in the UK, it is best to err more on the side of inorganic (60% – 70% inorganic) to ensure the pot is drained quickly.
