Succulents come in a range of shades, some naturally blotchy and others with different colors. A succulent that changes its color too much is a sign it's not healthy. The insects themselves are tiny dots, which hide in the folds at the base of the leaf. Inside the grow tent I've found my leaf propagating to be much more successful. Succulents of all kinds can survive in a garden tent. However, this is the best environment for growing succulents out of leaves. Leaf propagation is best done in a cool environment with enough light.
