Grower's Choice

Full Phase Spectrum, Engineered for Measurable Yield Gains

Grower's Choice designs every fixture around one principle: light output should be provable, not promised. The Full Phase spectrum drives PAR efficacy well above legacy HPS systems, carrying growers from vegetative growth through flower without switching fixtures mid-cycle.

Why Growers Choose the Full Phase System

Every Grower's Choice fixture solves the same core problem — inconsistent light delivery that stalls canopy development and inflates energy costs.

• PAR-Driven Spectrum: The ROI-FF 650W applies the Full Phase recipe at a mid-tier power draw, giving smaller commercial rooms the same spectral balance as the flagship models.
• Efficacy That Cuts Energy Costs: Grower's Choice fixtures push PAR efficacy well past 3.0 μmol/J, meaning growers switching off HPS typically see a sharp drop in monthly power draw without losing canopy density.
• Passive, Fanless Cooling: A silent bar-style build with no moving parts eliminates the fan-failure risk that plagues actively cooled fixtures mid-cycle.

Matching Wattage to Canopy Size

Sizing a Grower's Choice fixture comes down to canopy footprint and growth stage rather than raw wattage alone.

• Personal or Single-Tent Grows: The AG140 140W covers compact tents without the electrical overhead a hardwired commercial fixture requires.
• Commercial, Multi-Light Rooms: The PFS Series and ROI-F720 hardwired fixtures are built for 208-277VAC commercial electrical infrastructure, making rows of them straightforward to run off a single circuit plan.
• Centralized Control: Pairing any hardwired fixture with the Master Controller unlocks sunrise/sunset simulation and automatic high-temperature dimming across an entire room.

Getting the Most from a Full Phase Fixture

A few adjustments make the difference between an average harvest and one that fully uses the Full Phase spectrum's potential.

• Dial In Hang Height: Keep fixtures at the manufacturer-specified distance during flower to avoid light bleaching without sacrificing PPFD at the canopy.
• Dedicate a Fixture to Vegetative Growth: The ROI-FV Vegetative model is tuned specifically for that stage, freeing the flowering fixture from spectrum compromises.
• Start Clean at Propagation: Rooting cuttings on the Pro Pod Cloning System before they move under a Full Phase fixture shortens the time to a full, even canopy.

Matching the right fixture to canopy size, backing it with centralized control, and starting clean at propagation are what turn Full Phase specs into a repeatable harvest. For the wider range of options beyond this brand, browse the full LED Grow Lights selection.
