About 5 years ago, Sheridan Cleland of MyPDFscripts wrote the below article on his blog. Soon after, the site disappeared. I wanted to keep the memory alive, because these practices by the studios have not changed. They have only become worse.
Cacti are one of my favorite types of plants to grow inside all year and outside in summer. Unfortunately, the ambient air tends to stay moist during most seasons, a condition which makes cacti unhappy. Cactus potting soil can enhance drainage, increase evaporation and provide the dry conditions that cacti favor.
Cactus is a naturally-occurring plant that grows only on sand that is not connected to water. Cacti do not need light to grow and are non-flammable. Cacti inflict half a heart of damage when touched, so use caution when harvesting. The damaging property of a cactus can be used to create simple traps.
