Description
The ThinkGrow Model-I and Model-I Plus are high-performance 720W horticultural LED grow lights designed specifically for greenhouse and single-level indoor cultivation. Featuring an innovative V-shape LED panel design, built-in drivers, and advanced spectrum control compatibility with the TrolMaster Hydro-X ecosystem, these fixtures are built for serious growers looking to maximise canopy penetration, efficiency, and environmental control.
Both fixtures utilise a full-spectrum output with UV, Deep Red, and Far Red technology to better replicate natural sunlight across every stage of plant growth, from vegetative development through to flowering. The Model-I Plus expands further with independent 4-channel spectrum control capability when paired with the TrolMaster HCS-2 controller, allowing advanced growers to fine-tune spectral recipes with incredible precision.

What's The Difference Between The Model-I And Model-I Plus?
The standard Model-I is ideal for growers wanting a powerful full-spectrum commercial-grade LED fixture with Far Red support and Hydro-X compatibility.
The Model-I Plus pushes things further with higher efficiency, increased light output, more LED diodes, and fully independent 4-channel spectrum control when paired with the TrolMaster HCS-2 controller. This allows experienced growers to fine-tune UV, White, Deep Red, and Far Red channels independently for maximum environmental and spectral precision.
For growers chasing complete spectrum tuning and maximum efficiency, the Model-I Plus is the flagship option within the ThinkGrow range.
