Facts not feelings

Somewhere along the way choosing a grow light got complicated. MIGRO spent the last 2 years listening to their fans (and critics) to understand their concerns and needs – simultaneously they’ve tested over 150 lights on the market today.

The MIGRO ARAY is designed to take the guesswork out of picking the right grow light for you – better lighting performance with future-proof extendability from the team at MIGRO that you can trust.

 

Inspired by Nature

The ARAY spectrum is designed for full-cycle growth to generate tight, dense growth in the early vegetative stage and promotes vigorous growth with a high concentration of flavonoids & terpenes in the flowering stage.

Blue promotes short dense growth but is less photosynthetically efficient than other spectra. A minimum of 10% is required for healthy plant development.

Green light penetrates the plant canopy and individual leaves adding to the overall photosynthetic efficiency of the spectrum.

Red light is the most photosynthetically efficient and should be optimized to maximize yield potential.

ARAY Full spectrum is a white light 3500K color temperature and 80 CRI so you can inspect the health of your plants with clarity. 

MIGRO provides enough Blue light to regulate plant development and generate short, dense growth. This means the ARAY spectrum is suitable as a veg light and a full cycle grow light.

Green is nearly as photosynthetically efficient as blue on its own. However, mixed with red and blue into white light the green will reach the chlorophyll deeper in the leaf and canopy to maximize overall photosynthesis.

Red is the most efficient for photosynthesis and should be maximized but has little effect on plant shape. However, red light is the most efficient photosynthetically and a higher proportion of it will increase the overall system efficiency and therefore increase yields.

 

Modular – grows with you

These grow light modules can be joined end to end or hung side by side to cover any sized grow space.

 

High efficiency for maximum yield

The ARAY is highly efficient, allowing more light and yield generated for less power consumed – reducing electricity consumption and reducing heat levels in your grow room.

The high efficiency of the MIGRO ARAY grow light system means you get more yield per watt than any previous generation grow light system. Higher efficiency also means lower heat and lower power consumed keeping you stealthy and safe.

The MIGRO ARAY LED bars are designed to generate the best system efficiency and even light coverage for your grow area. No hot spots and penetration deep into the corners to reduce stress and maximize yield potential from every plant.
