Spider Farmer Quiet 4 Inline Duct Fan with Speed Controller and Full Spectrum LED Grow Lights

Revised Content:

【QUIET & POWERFUL】This 4" exhaust fan boasts a mixed flow design combined with an EC motor that powers high-quality impellers, making it more energy-efficient than a traditional inline fan. Despite its modest 35-watt power consumption, it delivers a strong airflow of up to 205 CFM, while maintaining a remarkably low noise level of only 28 dB, ensuring a silent operation. Lightweight ABS blades further reduce airflow resistance, enhancing the overall performance by 40%.

【BUILT TO LAST】Crafted with premium ABS plastic housing, this exhaust fan is built for superior durability. With an IP42 rating, it is highly resistant to dust and liquids, ensuring reliable performance even in harsh environments. The fan is also ETL/FCC listed, further reinforcing its quality and safety.

【ADJUSTABLE SPEED】The integrated fan speed controller allows you to freely adjust the fan speed, enabling you to optimize the airflow for the optimal growth of your plants.

Hight Light Output: The 2024 New Version SF300 grow lamp utilizes OSRAM diodes with 192 LEDs, producing a remarkable 5000 lumens output. Remarkably, it achieves this with only a 32-watt power draw, making it significantly more energy-efficient and cost-effective than traditional fluorescent T5 bulbs. The reflectors further enhance the focus and efficiency of the light, improving luminous flux and light concentration. By switching to the SF300, you can expect to double your harvest per dollar spent on electricity.

Sunlike Full Spectrum Grow Light: Featuring a 120° beam angle, this plant grow light emits a broadband full spectrum, including 660-665nm (RED), 730-740nm (IR), 2800K-3000K (WARM-WHITE), and 4800-5000K (BLUE). This comprehensive spectrum has a significant impact on plant germination, flowering, fruiting, chlorophyll synthesis, and photosynthesis, ensuring optimal growth for your plants.
