Growing Cat Palm (Chamaedorea cataractarum) Under Artificial Light

100W equivalent 24W CFL cool white bulb

Combined CFL and 32W Philips linear cool white fluorescent

Reader Question

My new Cat Palm gets almost no natural light in my apartment. I'm using a 24W CFL (cool white) and a 32W Philips linear fluorescent (cool white) on an 8/16 hour timer. Is this sufficient until spring? What artificial lighting do you recommend?

Assessment: Adequate for Short-Term

Your setup is probably fine for several months. Cat Palms prefer bright indirect natural light, but fluorescent lights provide strong blue spectrum (for foliage) and some red (for flowering).

Optimization Tips

• Swap one cool white bulb for warm white to balance blue/red spectrum.
• Raise the CFL to spread light evenly — flood bulbs are better than spotlights.
• Keep the fluorescent tube close — light intensity drops sharply with distance.
• Change timer to 12 hours on / 12 hours off for better growth rhythm.

Long-Term Outlook

Artificial light cannot fully replace sunlight. Move the palm to a bright window (east/west) when possible. Avoid direct sun, which scorches leaves.
