3. Operating Instructions
The SF300 provides a sunlike full spectrum light, crucial for all stages of plant development. This includes specific wavelengths for germination, flowering, fruiting, and photosynthesis.
Light Spectrum Details:
- 660-665nm (RED): Essential for flowering and fruiting.
- 730-740nm (IR): Promotes robust stem growth and proper node spacing.
- 2800K-3000K (WARM-WHITE): Boosts plant blooms and makes them more vivid.
- 4800-5000K (BLUE): Accelerates germination and increases plant growth rate.
