fans are essential, especially with hps lighting. plants don't have lungs. they have no way to expel air from the cells of the leaves, other than simply allowing it to float out. if the air is still, they effectively suffocate. also, with sodium lights, heat is usually an issue. MOST canna plants prefer temps of around 28 degrees C.Dr. Greenthumb wrote:Well like I said it's only necessary if heat and smell are a problem.
Another good way to prevent smell is by never touching the plant once it starts developing crystals. I dont know from personal experience but I know a few people who have tried it and had zero smell.
