ThinkGrow Model-i

Model-I is designed specifically for greenhouse and single-level indoor cultivation.


This fixture is a high performance LED grow light for indoor horticulture cultivation. The compact design with built-in driver combines both energy efficiency and practicality for the human work environment, while the innovative V-shape LED panel design improves light distribution by providing a wider angle of photon distribution. This reduces the distance needed between the light and the canopy, which in turn reduces total light energy loss.

The full spectrum design with added UV provides a better spectrum than many other fixtures (similar to natural sunlight), covering each critical phase of growth from vegetative to flowering.


External Control

The extra Far Red spectrum channel allows a 10-15 minute exposure under Far Red, which can be applied to crops to help finish the flowering cycle faster (External Controller required). It provides great external control ability and allows up to 256 fixtures per channel with great efficiency at 2.54 umol/J.

The Model-I is only compatible with TrolMaster Hydro-X control systems. With the TrolMaster lighting adaptor LMA-T, the Full Spectrum and Far Red channels can be controlled independently from the Hydro-X controllers. This will allow the Far Red channel to be turned on 10-15 mins after light off to help finishing the flowering cycle faster. One LMA-T adaptor can run up to 256 fixtures in the same daisy chain channel.

Please note that the Model-I will operate at Full Spectrum Channel only without being connecting to the controller.
