Mars Hydro SP 3000 Full Spectrum 300W LED Grow Light

300W LED grow light with high red spectrum, waterproof build, and silent cooling for 2x4 ft high-PPFD grow setups Penetration power meets precise control—the Mars Hydro SP 3000 is built for growers who need deep canopy reach and a boosted red spectrum to drive explosive flower and fruit production. This 300W full-spectrum LED floods a 2x4 ft area with intense, uniform PPFD that maximizes photosynthesis across all growth stages. Running high-humidity rooms or stacked vertical setups? No problem. The SP 3000’s waterproof build and passive cooling keep it running cool and quiet, with zero moving parts to fail. Dimming is easy—manually or across up to 50 linked units with commercial RJ11 controls. Whether you’re dialing in a tent grow or syncing a full room, this light performs. Is the Mars Hydro SP 3000 Energy-Efficient? Yes. With a PPE of 2.8–3.0 µmol/J (based on chipset class), this light far exceeds HPS fixtures (1.3–2.1 µmol/J). That means better yields per watt and lower power bills.
