Why Buy From Grow Tents Depot
  • Equipped with Samsung LM301B Diodes: The Mars Hydro FC3000 300-watt LED grow light is powered by high-performance Samsung LM301B chips, delivering a high Photosynthetic Photon Efficacy (PPE) efficiency of 2.85 umol/j and long-lasting color rendering capability, providing indoor plants with sufficient and enduring lighting energy.
  • High PPF Output and Uniform Light Distribution: With a high PPF output of 854 umol/S, the FC3000 provides even distribution of grow lighting through its multi-light bar design and dense diode layout, optimizing Photosynthetic Photon Flux Density (PPFD) for consistent growth in every part of the coverage range.
  • Exclusive Full Spectrum Lighting Recipe: Enhanced with blue and red light, the full spectrum of the FC3000 stimulates plant growth and promotes the accumulation of plant-based phytochemicals, while abundant red light improves the maturing process and flower quality of plants.
  • Adjustable Light Bar Layout: The movable light bar allows for the free adjustment of light density at different points within the effective coverage area, maximizing light utilization and creating an even crop. The design is also easy to install, store, and replace.
  • Daisy Chain Dimming Function: The FC3000 grow light features a dimming knob that adjusts brightness from 0 to 100%, allowing for customized brightness levels during different plant growth stages, while saving on electricity costs. With the daisy chain function, up to 30 LED grow lights can be connected at the same time and controlled by one master light for turning on/off and dimming.
  • Fast Heat Dissipation: The wave-shaped heat sink dissipates heat quickly, maintaining a cool LED light that will not affect the stable environment that has already been controlled. The multi-bar style design also prevents hot spot issues due to reserved space between light bars for cooling.
  • DLC Certified Grow Lighting Solution: DLC-certified LED grow lights meet the highest standards in the industry and offer high efficiency, capable of operating for at least 36,000 hours while maintaining 90% efficiency. Mars Hydro provides a 5-year warranty and local repair services to ensure the LED grow lighting is functioning correctly and perfectly within its service life.

    My opinion

    Great lights I recommend them for first timers and pro’s looking for change.


    I'm really excited about the way things are going to turn out.
    having the ballast attached to the outside of the tent will make a huge difference to this round!
    very pleased with this product and they sent it to me like 3 weeks sooner than expected!
