This discussion centers on the feasibility of using static electricity to manage rainwater for cacti cultivation in tropical climates. Participants suggest that building a charged scaffold may not effectively repel moisture due to the inherent challenges posed by humidity. A retractable roof is recommended as a more reliable solution to handle heavy rainfall. The discussion concludes that succulents may be a more suitable alternative for such environments.
