Introduction

LED grow lights are the newest trend for the cultivation of indoor plants. Using an advanced full spectrum LED grow light will provide your plant/s with a broad spectrum of light that is similar to natural sunlight and so enhances the process of photosynthesis.

Red and blue LED lights have been proven best for encouraging plant growth, and so this light provides the user with the option to use red, blue or a combination of the two colours to obtain the best kind of light for their plant/s.

The main part of the GLH light is blue (peak 450nm) and red (peak 660nm), which supplies the most efficient wavelength to enhance photosynthesis performance. This model allows you to choose between having more red or blue light, or a balance of the two.

Installation

Setting up your grow light is simple to do.

Remove all packaging and set aside.

Attach the hanging wire to the top of the light unit as shown (right).

Find a suitable place to hang the light, taking into account the optimal distance needed for the growth of your plants.

Hang up onto a place strong enough to support the weight of the light.

Care and Maintenance

Before cleaning ensure the lamp is unplugged from the mains socket.

Do not submerge this lamp in water or any other liquid.

Do not use corrosive cleaning products on it.

To clean, simply use a dry cloth to dust and clean all over the lamp.

If not being used for a long period of time, store inside a protective box in a cool dry place.

DURONIC

Using Your Grow Light

For best results create a space specifically for growing your plants.

Placing reflective walls around the space will enhance the effects of the LED lights as they will redirect escaping photons back towards the plants.

Recommended Hanging Height and Time Guide

Plant Lifecycle	Power On	Power Off	Mounting Height
Seeding stage 8h 16h 24”
Growing stage 14h 10h 22-24’
Vegetable stage 14h 10h 20-22”
Bloom stage 12h 12h 18”

It is important to consider the optimal hanging height and distance the lamp will be from your plants. To get the best results from your grow light, we recommend the heights and time cycles in the table above for a successful yield.

Note: keep an eye on your plants to see how receptive they are to the light mode you are using. If the leaves start to look dry, limp or discoloured, consider changing the mode or using the light for less time.

The 3 Light Modes

VEG: blue light mode

BLOOM: red light mode

VEG & BLOOM: red and blue light combined

To activate VEG & BLOOM mode both switches need to be switched on together
