The phytochrome, a light detector found in plants, regulates a variety of processes related to plant growth, such as seed germination, chlorophyll production, seedling elongation, leaf growth and movement, and blooming timing. It detects light at two different wavelengths: red light (660 nm), which activates it, and near-infrared (730 nm), which deactivates it. A plant employs phytochrome activity to calculate the duration of the day and then the season since red light prevails in strong sunlight and far red light predominates in shade.
Are Grow Lights Safe For Humans?
Since the windows in my new apartment are all heavily shadowed, I recently bought a grow light for my plants. I’ve never owned a grow light before, so I’m a little worried about the negative effects on me with an LED grow light.
