Frequently Asked Questions (FAQs)
1. What kind of lightbulb do you need for growing plants?
When growing most houseplants, use light bulbs between 4000 and 6000 Kelvin, as the bulb's color temperature will borrow from a full spectrum of colors—cools and warms. With these lights, you can actually mimic the growth you would get in a greenhouse or outdoors.
2. Can any LED light be used as a grow light?
Regular LED lights can't be used as grow lights, even though they may emit some of the wavelengths necessary for plants. Regular LED lights don't emit enough of the light that plants require. Plant growth primarily requires red & blue light, which LED grow lights are designed to maximize.
3. What color light bulb is best for plant growth?
What Color Light is Best for Plant Growth?. Violet-blue light in the 400 – 520 nanometer range encourages chlorophyll absorption, photosynthesis, and growth.Red light in the 610 – 720 spectrum range promotes flowering and budding.
4. Can you grow a plant under a light bulb?
Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum. They're excellent for seedlings as well as houseplants, culinary herbs and other plants.
