Lighting for Orchids: The Key to Blooms Without Burn

Light drives flowering. Too little = no blooms. Too much = yellow, scorched leaves.

Read the Leaves

Medium green = perfect. Yellowish = too much. Dark green, limp = too little.

Window Strategy

North: low light (Phalaenopsis). South: high light (Cattleya, Vanda)—sheer curtain in summer. West: intense afternoon = risk. East: gentle morning = ideal for many.

Artificial Light

Supplement or replace. LED grow lights: full spectrum, timer-controlled (12–14 hrs). Give dark rest period.

Temperature Nuance

Most like warm days (75°F), cooler nights (50–60°F). Cymbidiums need cooler. Conservatories overheat—shade essential.

Light isn't optional—it's the bloom trigger. Match species to source, and watch flowers follow.
