5.2 Full Spectrum Output
The SF2000 utilizes Samsung LM301H EVO LEDs to provide an optimized full spectrum of light, including 3000K, 5000K, 660nm (red), and 760nm (IR). This spectrum supports all growth stages from germination to bloom.
- 5000K: Promotes germination and vegetative growth.
- 3000K: Boosts flowering and fruiting.
- 660nm (Red): Accelerates growth and enhances bloom.
- 760nm (IR): Increases yields and plant vigor. Note that IR light appears dim to the human eye.
