Growing Cactus Under Fluorescent Light
A good discussion of the topic. Here’s an extended quote, if nobody minds.
These succulents, some spiny, some smooth, in shades of silver, green, red and lavender, are arrayed on a lengthy, three-tiered light stand, each level equipped with four 48-inch, 40-watt full-spectrum bulbs purported to resemble natural light….
Most species I have tried (there are more than 1,000 cactus species) decline gradually over a period of 18 months to two years. A few, however, including species of Mammillaria, Melocactus, Echinocereus and Gymnocalycium, have thrived.
Among the non-cactus succulents that flourish under fluorescents are species and hybrids of Haworthia, Aloe, Edithcolea, Adromischus, Agave, Aeonium, Crassula, Sedum, Echeveria, Euphorbia, Gasteria, Graptopetalum, Kalanchoe and Sansevieria. Others, such as Stapelia and Senecio species, do well if given occasional R&R on an east-facing windowsill.
More species listed at the article, if you click through. We also suggest to people in offices to make sure their full spectrum bulbs are within 12″ of the plant, because the UV from them dissipates quickly.
