Who This Is For

  • You are adding under-canopy lighting because the dense foliage on your plants shades lower branches and reduces yield
  • You are integrating supplemental rings because you want to keep lower leaves active instead of letting them yellow off

What We Found

  • We suggest placing these lower than you think because the rings handle close proximity without burning lower leaves
  • The 0-100% dimming is a huge win for balancing light intensity as your crop reaches the final weeks of flowering

What Users Say

  • Growers who installed these under the canopy say they stopped seeing small larf on lower stems during harvest
  • Users who added these rings report much more uniform development across the entire height of their plant material

Elufah Saturn720 | Supplemental Under-Canopy LED System

The Elufah Saturn720 provides supplemental under-canopy lighting to increase flower density in the lower third of the plant. This 72W system uses three 24W ring lights to penetrate areas typically shaded by the primary overhead fixture. It targets the lower nodes to prevent larf and ensure a more uniform harvest across the entire crop profile.

Features

Full Spectrum Output

The system combines 4000K white, 437.5nm blue, and 660nm red diodes to support both vegetative growth and flower development. This specific wavelength mix ensures lower leaves remain metabolically active.

3-in-1 Smart Controller

The integrated power controller manages dimming, timing, and power cycles from a single interface. Programmable modes allow for precise light scheduling without external timers.

Adjustable Telescoping Pole

The support pole extends from 12 to 22 inches to accommodate various plant heights. This allows the light source to remain at the optimal distance from the lower canopy as the plant grows.

Open Base Airflow

The sturdy base is designed to fit around pots or grow bags while maintaining critical airflow. This open architecture prevents moisture buildup and ensures proper drainage to protect root health.

In Detail

Elufah Saturn720 Under Canopy LED Grow Light 3 Ring Lights 72W — application view 2

The Saturn720 is engineered to solve the common issue of shaded lower branches in dense grow tents. By providing light from the floor up, it stimulates photosynthesis in areas that typically receive less than 10% of the overhead light intensity. This supplemental energy converts what would be low-quality flower into dense, marketable yield.

  • Independent 24W ring lights for targeted placement
  • 0-100% intensity control for sensitive lower leaves
  • AM/PM toggle and time adjustment for easy scheduling
  • Low heat output to prevent scorching of lower foliage
  • Energy-efficient design minimizes additional power draw

Frequently Asked Questions

Will this light increase the temperature in my grow tent significantly?

No, the Saturn720 uses high-efficiency LEDs that produce very little heat. While it adds 72W of total power, the heat is distributed across three rings and is easily managed by standard tent ventilation.

Does the base interfere with pot drainage or cause root rot?

The base is specifically designed with an open structure to accommodate pots and grow bags without trapping water. It allows for full airflow around the base of the plant to keep the root zone healthy and dry.

Can I set the lights to turn on and off automatically with my main light?

Yes, the 3-in-1 smart controller includes a built-in timer function. You can program the T.ON and T.OFF modes to synchronize perfectly with your primary overhead lighting schedule.

What is the best height to set the ring lights?

The telescoping pole allows for 12 to 22 inches of adjustment. We recommend positioning the rings so they are level with the lower third of your plant's canopy, adjusting upward as the plant grows.

Can I dim the lights if my plants are in a sensitive vegetative stage?

Yes, the controller offers 0-100% dimming intensity. This allows you to start with a lower light output for younger plants and increase it as they enter the flowering stage and require more energy.
