Q: Is there a way to keep my cat from eating my succulent plant? It is usually not necessary to potter or replant an Echeveria plant if the plant has been harvested in large quantities. They will be most successful in soil that drains quickly than any succulent potting or cactus mixes. Is Aloe Vera a Succulent or a Cactus? Aloe Vera can grow to three feet outside but will do very well under artificial or partial lighting. While the blue spectrum of your grow lights can aid in photosynthesis and contribute to plant growth, it is not as important as the red spectrum.
