Inconsistent light recipes lead to uneven canopy growth and wasted energy — the ThinkGrow Model-I Plus 720W solves this with four fully controllable spectrum channels (UV, White, Deep Red, and Far Red), giving commercial growers precise control over how their plants develop at every stage.
The Model-I Plus pairs this spectrum flexibility with a compact, V-shaped single-bar design that increases light penetration and shortens canopy distance, helping produce denser, healthier growth throughout the canopy. Paired with the TrolMaster HCS-2/3 controller, growers can manage up to 256 fixtures from a single interface while running at an industry-leading 2.7 µmol/J efficacy — more usable light per watt, with lower operating costs over the life of the fixture.
Precision spectrum control lets you match light output to your plants' changing needs at every stage.
The V-shaped design increases light penetration and reduces canopy distance for stronger results.
Manage up to 256 fixtures per channel from a single TrolMaster HCS-2/3 controller.
Runs at 2.7 µmol/J, maximizing yield potential while minimizing energy costs.
The Model-I Plus offers full control over UV, White, Deep Red, and Far Red channels, letting growers build custom light recipes for every stage of the grow cycle. Channel control is accessed via the TrolMaster HCS-2/3 controller.
