1. What is Far Red Light?
Far red light refers to a specific range of light wavelengths, typically between 700 and 800 nanometers, which is just beyond the visible red spectrum. In cultivation, far red light plays a significant role in regulating various physiological processes.

2. Far Red Light and Flowering
Photoperiodism, the response of plants to light cycles, is influenced by far red light. Manipulating the red to far red ratio can trigger flowering, optimizing the timing and quality of flower production.

3. Targeting the Emerson Effect
The Emerson effect refers to a fascinating phenomenon observed in photosynthesis. When chloroplasts (the cellular structures responsible for photosynthesis) are exposed to specific wavelengths of light, their rate of photosynthesis significantly increases.

This effect was first discovered by scientist Alexander Emerson in 1957, and it has since been extensively studied by plant biologists.

While the Emerson Effect is typically associated with increases in photosynthesis, it can also lead to other changes in plant physiology, such as increased cell division and growth.

One effective way to leverage the Emerson Effect is by using a supplemental far-red light bar for 10-15 minutes after turning off full-spectrum lights.

4. Artificial Use of Far Red Light in Indoor Cultivation
More and more growers utilize far red light in controlled environments to regulate growth and flowering. Flexstar far red light bars include specific wavelengths of far red light to mimic natural sunlight conditions and maximize cannabinoid production!
