મુખ્ય તથ્યો

• 18/6 or 20/4: standard vegetative growth cycle for most crops
• 12/12: triggers flowering in short-day plants (cannabis, some chrysanthemums)
• 16/8: common for most herbs, lettuce, and leafy greens — extends harvest window
• 24/0 (continuous light): used for some seedlings and microgreens; causes stress in some species
• Use a timer for consistency — irregular light cycles stress plants and can disrupt flowering
• Day-neutral crops (lettuce, most herbs) produce continuously regardless of light cycle length
