O+ Series 300W

Groplanner’s O+ Series 300W is a modular, dimmer‑knob controlled LED grow light built for 2' x 4' tents. The fixture uses a targeted full spectrum with 3000K and 5000K white, 660 nm deep red, and 760 nm far‑red diodes, and is rated at 2.75 µmol/J photon efficacy. A fanless fin heatsink aids passive cooling, and the O+ platform supports daisy‑chain control via an RJ14 port for linking multiple units. The light is designed for all growth stages and emphasizes efficient canopy coverage in compact home grow spaces. Groplanner specifies a 60,000‑hour service life.
