Description

The 30W LED Bar Grow from 4Twenty has been specially developed for growers who want to achieve optimal results during the growth phase. Thanks to its tailored growth spectrum, this LED Bar supports a compact plant structure, healthy leaf development, and strong root formation.

Due to its limited heat generation, the lamp can be placed close above the crop, efficiently illuminating young plants, cuttings, and mother plants without the risk of burning.

Suitable for

  • Cuttings
  • Seedlings
  • Mother plants
  • Vegetative growth phase
  • Grow cabinets
  • Grow tents
  • Vertical farming

Recommended settings

The 420 LED Bar Grow is designed to be placed close above the crop for maximum efficiency.

Cuttings

  • 15-20 cm above the crop

Seedlings

  • 10-15 cm above the crop

Mother plants

  • 10-20 cm above the crop

Vegetative growth

  • 10-15 cm above the crop

Always monitor how the crop reacts and adjust the distance if necessary.

Ideal for mother plants and cuttings

The growth spectrum of the 420 LED Bar Grow supports compact plant development with strong side branching and healthy leaf growth. This makes the lamp particularly suitable for mother plants that need to produce cuttings regularly.

The LED Bar also offers an efficient and energy-saving solution in cutting rooms and grow cabinets.

Flexibly expandable

Thanks to the Daisy Chain functionality, multiple LED Bars can be easily linked. Grow LED Bars can be combined with the 420 Full Spectrum LED Bars, creating a flexible lighting system that can be easily adapted to the needs of the crop.

Waterproof and maintenance-free

The IP66-certified housing protects the electronics from moisture and dust. Thanks to passive cooling, the lamp operates completely silently and requires no maintenance of fans or other moving parts.

Build your ideal light source yourself

With the handy optional LED Bar Mounting Kit, you can easily combine multiple LED bars (of the same length) into one powerful fixture. Attach up to 10 LED bars to two sturdy aluminum brackets and connect the lamps to each other with the Daisy-chain connectors. This way, you can quickly create one large, powerful lamp, suitable for any grow room.
