A plant's perception of day length usually determines the flowering and vegetative growth response. The slow inactivation of phytopigment photoreceptors begins before the plant is completely "asleep," lasting more than 12 hours of dark flowering.

TotalGrow Far Red Lullaby lights specifically target the absorption peaks of Phytochrome Pfr to speed up this process, reducing the 12-hour dark requirement and allowing more daily light accumulation and growth.

Exact dark requirements vary by crop and environment, but can typically add 1 hour of growing time per day to 13 hours per day/11 hours of the night.

This 730nm far-red radiation typically also causes stretching.

• Using 730nm far-red light to accelerate the transition to darkness-induced 'rest'
• Enabling longer periods of high-intensity lighting to increase growth rates and yields
• Reduced need for blackout curtains and natural short days
• Simple installation with minimal power consumption and electrical infrastructure requirements
• Run for 1 hour after 13 hours of high-intensity lighting, then 10 hours in the dark.
