Spider Farmer GrowR40 Deep-Red LED Bars | 40W
Spider Farmer GlowR40 Deep-Red LED Bars | 40W
The Spider Farmer GlowR40 Deep-Red LED Bars are specialized supplementary lighting designed to maximize photosynthesis during the critical flowering and fruiting phases. The system uses a targeted deep red spectrum (650-665nm) to significantly boost the yield and vitality of your plants. Consisting of two highly efficient light bars (20W each), the GlowR40 can be seamlessly integrated into existing setups with main lights under 500W (such as SF2000, G5000, or SE5000).
Targeted Yield Increase through Deep Red
The red LED diodes in the 660nm range are crucial for controlling flowering impulses and fruit development. By utilizing this wavelength, the plant's energy efficiency is optimized, leading to more robust growth and heavier fruits. For optimal results, a specific schedule is recommended: Turn on the deep-red light 10 minutes before the main light ("Wake Up"), let it run during the day phase, and turn it off only 10 minutes after the main light ("Plant Sleep").
IP65 Protection and Flexible Mounting
The GlowR40 features an IP65-certified, waterproof, and transparent lampshade. This reliably protects the LEDs and circuitry from moisture and dust, guaranteeing a long lifespan even in high-production hydroponic systems or greenhouses. Thanks to versatile installation options, the bars can be mounted horizontally or vertically on the sides, bottom, or as top lighting to eliminate light shadows in the lower canopy.
Daisy-Chain Functionality
The system is designed for professional scalability. Using the integrated daisy-chain function, up to 32 individual light bars can be connected in series and centrally controlled at a mains voltage of 220V. This saves installation time and ensures clean cable management.
