How light Movers Work

Read excellent Max Yield article by Sara Elliot- Straight talk about light movers

Successfully utilising a light mover provides better light efficiency, electricity savings, increases light coverage and results in a heavier harvest with better plant growth.

The Jupiter 2 light mover effectively reduces shading and provides increases of around 20% to your yield. The science behind this product relates to the plants containing phytochromes, photoreceptors that control physiological and developmental reactions to fluctuations of red and far red light.

By utilising the light mover, the angle of light incidence received by the lower leaves and stems will be continuously changing so the red to far-red ration will be kept at the correct levels. The Jupiter II ensures much healthier plant growth and even canopy distribution.

The Jupiter 2 also avoids burning and overheating of plants, by using a J2, you can efficiently lower the lamp without risk of damage to provide a higher light intensity to your crop. Fixed lighting must be mounted at a height that significantly reduces the light intensity below the plant canopy.

Jupiter 2 Light Mover Advantage List

The Australian made Jupiter 2 light mover is a world leader of light mover technology servicing the hydroponics industry. Manufactured now for over 33 years and distributed throughout Australia and New Zealand, the Jupiter 2 has passed all tests regarding quality and reliability and excellent service support..

Light movers would have to be the hardest working piece of kit in a grow room so must be sturdy and reliable. We understand that to give you peace of mind that your mover will do the job for many years of service. It's not unusual to get 20 years out of these motors. All parts are available so we can service them to avoid landfill.

It has been designed to an exacting specification using only the highest quality components, from the Swiss designed motor/gearbox down to the ROHS compliant electronic delay system.


  • Reduce the lamp to plant distance without burning the tender growing tips of the plants
  • Reduce power costs
  • Increase the penetration of the correct intensity light below the plant canopy
  • Keep the ratio of red to far-red light even below the plant canopy
  • Increase yield due to increased budding sites
  • Healthier, more even growth patterns - higher yielding plants
  • Increased air flow due to the movement of the lamps heat - decreased fungal growth.
  • Manufactured in Australia from high quality parts
  • Serviced in Melbourne Australia by Niccoponics
  • 2 year warranty
  • Move from 1 light up to 6 lights
  • Motor with time delay, 0 - 60 seconds
  • Rails can be cut down according to exact size required

LIGHT INTENSITY

To avoid burning and overheating of the plants, fixed lighting must be mounted at a height that will significantly reduce the light intensity below the plant canopy.

See - INVERSE SQUARE LAW (Basically all the inverse square law says is that an object that is twice the distance from a point source of light will receive a quarter of the illumination).

RED AND FAR RED LIGHT (660 / 720 nm)

Far-red light plays a significant role in plant growth. It is a major factor in promoting the shade avoidance (stem elongation, stretching) response in plants.

Plants absorb red light (660-680nm) and a portion of far-red (720 -740nm).

Plants contain phytochromes, photoreceptors that control physiological and developmental reactions to fluctuations in levels of red and far red light.

Some responses that are regulated by phytochromes include:

  • germination
  • stem elongation
  • flowering
  • gene expression
  • leaf and chloroplast development.

THE RED TO FAR RED RATIO

It is vital to keep the ratio between the red to far-red wavelengths of light at the correct levels, above and below the canopy, if you wish to achieve optimal plant growth and increased yields.

Plant leaves filter light, allowing more far-red light to pass through than red or blue light. The resulting change in this ratio will cause undesirable growth below the canopy.

It is also important to note that a low red to far-red ratio is created when plants are close together and are growing under stationary lights.

Moving the lights effectively reduces shading. The angle of light incidence received by the lower leaves and stems will be continuously changing so the red to far-red ratio will be kept at the correct levels.

Much healthier plant growth will be achieved as the ratio will now be at the correct levels for optimal growth.
