Frequently Asked Questions
Why does my golden barrel cactus have Light needs?
Cause: Cacti are high-light plants evolved for desert environments with 6-8+ hours direct sun daily. Indoor conditions typically provide only 100-500 foot-candles, triggering etiolation—elongated, weakened growth as the plant stretches toward light sources. Conversely, sudden exposure to intense direct sun after low-light adaptation causes photoinhibition and sunburn, damaging chlorophyll and creating bleached, necrotic tissue. Both issues stem from light intensity mismatch with the plant's photomorphogenic requirements.
Solution: Target light intensity: 2000-5000+ lux for most cacti (6+ hours direct sun outdoors)
Prevention: Acclimate new plants gradually to full sun; maintain consistent high-light environment year-round; use grow lights in winter when natural light drops below 6 hours; avoid abrupt transitions from low light to direct sun.
