I bought 3 different cactus plants that were all "outlined" in red. One is a jade, one is a hen and chicks type, and the other I don't know (ech???). All have lost the red outline. They sit about 10-12 inches under a plant light. I just lowered the light a couple days ago. Anybody know if this is a seasonal thing, or is the light just not strong enough? What brings out the red outline?
Thank you in advance,
Leda
