1. Can I use it to grow cannabis?
Yes, CSY-QB1276-480W is perfect for growing plants that require a lot of light, such as tomatoes, cucumbers, cannabis, and other plants.
2. How to protect my eyes from LED grow lights?
You should wear professional glasses when working with your light. Protective glasses with UV and IR coating can filter out dangerous rays and reduce eye strain.
3.What certifications do your grow lights have?
We can provide CE, FCC, RoHS, and UL certification.
4. Can LED grow lights really replace natural sunlight?
Yes, LED grow lights can help your plants grow. The Red and blue light in grow lights are the most beneficial color for plant photosynthesis.
5. How far should this grow light be from the plants?
For most plants, you can aim for 60cm (24 inches) during flowering (870 µmol/m²/s).
6. How to calculate the number of LED grow lights that I need in my growing area?
To determine the ideal number of LED lights for your plants, one method is to use the suggested wattage per square foot. For instance, during the vegetative stage, most plants need 30 to 50 watts of light per square foot, and during the flowering stage, 50 to 70 watts per square foot.
