Mars Hydro SP 3000R LED Grow Light delivers powerful 650–665nm red spectrum with 3.3 µmol/J efficiency for peak flowering yield in greenhouses and 2x4 ft grow setups

300W red spectrum LED grow light optimized for flowering, with 3.3 μmol/J PPE and IP65 waterproof rating for greenhouse use.

Target your flower phase like a pro—the Mars Hydro SP 3000R is a red-spectrum powerhouse designed to boost yield and quality during bloom. With a precise 650–665nm wavelength range and a PPE of 3.3 µmol/J, this 300W LED delivers deep light penetration to support stacked colas and uniform bud development in 2x4 ft spaces or as supplemental greenhouse lighting.

If you’re running greenhouses, outdoor farms, or blending with HID/LED rigs, this compact fixture fits right in. It’s slim, waterproof, and daisy-chainable up to 50 units—built to handle humid environments and cloudy-day conditions without missing a beat. Quiet passive cooling and easy dimming make it perfect for growers who want precision without the noise.

Is the Mars Hydro SP 3000R Energy-Efficient?

Absolutely. With a 3.3 µmol/J PPE, this light far outperforms HPS (1.3–2.1 µmol/J) and even many full-spectrum LEDs. That means more usable light, better bloom density, and lower electricity costs. Built for production, not just power.

Features

  • Flower-Focused Red Spectrum delivers a concentrated 650–665nm wavelength output, specifically engineered to enhance flowering and fruiting stages for higher yields and superior crop quality in both commercial and home greenhouse setups.
  • Market-Leading Efficiency offers a stunning PPE of 3.3 μmol/J and a PPF of 727.2 μmol/s, ensuring powerful light output with deep canopy penetration—ideal for greenhouse supplemental or top lighting applications.
  • Silent Passive Cooling features a durable aluminum heat sink that maintains optimal operating temperatures without noisy fans. The slim form factor minimizes crop shading while maximizing light delivery.
  • IP65 Waterproof Protection enables worry-free operation in high-humidity environments, safeguarding the fixture against moisture, heat stress, and long-term degradation.
  • Precision Light Control with built-in dimming functionality allows growers to adjust intensity across growth cycles. Supports daisy-chaining up to 50 units using RJ ports for seamless light management across large-scale operations.
  • High Yield Potential offers up to 2.9 grams per watt, outperforming traditional HID systems and complementing other LED or HID lighting solutions in mixed-light greenhouse environments.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
