TotalGrow Solark KC 250W LED Grow Light | 3-Channel Spectrum Control

The Solark KC 250W features three independent channels: White/Red (primary), Blue, and Far-Red. To promote rapid expansion and canopy development, increase Far-Red while keeping Blue lower. When you want to enhance quality, pigmentation, and structural density, increase Blue and reduce Far-Red. Each channel can be controlled via onboard dials or RS-485 communication for automated control.

The Solark KC 250W is optimized for vertical farming applications including leafy greens, herbs, and small fruiting plants. The tunable spectrum ranges are specifically designed around the most beneficial wavelengths for these crop types, allowing you to fine-tune growth characteristics. For early-stage propagation, the TotalGrow Stratum 10 clone light is specifically designed for seedlings and clones.

Yes, the Solark KC 250W supports daisy-chaining with capacity varying by input voltage: up to 5 fixtures at 115V, 10 at 208V, 11 at 220V, 14 at 277V, or 24 at 480V. This scalability is a key feature of commercial LED grow light setups, allowing for simplified power distribution and synchronized spectral control across your entire growing area.

Absolutely. The Solark KC 250W carries an IP66 waterproof rating, providing complete protection against dust ingress and powerful water jets. This makes it ideal for vertical farming environments where humidity levels can be high and regular cleaning or sanitation is required.

The typical mounting height for the Solark KC 250W is 8-12 inches above the canopy. This positioning provides optimal PPFD distribution and uniformity across the 4x4 ft coverage area. For a detailed explanation, you can read our guide on the science of grow light distance.

Individual 250W fixtures accept 100-277V input and include their own integrated power supply, making them ideal for smaller installations. The 4-light set features distributed 1000W power supplies designed for 208-480V input, offering a cost-effective solution for larger operations. For growers seeking a single high-power fixture, the TotalGrow Solark KC 1000W offers a similar solution with 4-channel control. For those who prefer a fixed-spectrum solution with high output, the TotalGrow 345W Bar LED is another excellent option.

Different light wavelengths trigger specific plant responses. Blue light promotes compact growth and enhanced pigmentation, while Far-Red light encourages stem elongation and rapid leaf expansion. By independently controlling these channels, you can optimize plant architecture and quality. Understanding what light color is best for plant growth is key to maximizing these effects.

With its high 2.8-2.9 µmol/J efficacy, the Solark KC 250W is one of the most efficient LED grow lights available and can reduce energy consumption by 30-70% compared to HID or fluorescent alternatives while maintaining or improving crop quality. This efficiency contributes to significant operational cost savings over the fixture's 50,000-hour lifetime.
