Artificial Lighting for Venus Flytraps: CFL vs. Shop Lights

A grower bought a flytrap from cobraplant.com, has a 26W CFL (1600 lumens) desk lamp. Asks if it's enough or if 40W needed.

Reality Check

Outdoor full sun is optimal. Indoor is difficult – expect losses while learning. CFLs: poor coverage, run hot, lumen drop-off fast. Better: multi-bulb shop light tubes (40W). Minimum 12,000 lumens (4 tubes) 4–6 inches away. Author now uses 6 banks (38,400 lumens) 8–10 inches away. S. purpurea color indicates adequate light. 3 CFLs + south window might work for a few plants. Dormancy management is another challenge.

Bottom Line

Indoor temperate CP growing is possible but resource-intensive. Author took 32 years to master; now has dozens of flytraps from one original plant.
