Atreum Hydra - 1000 LED grow light (100w)

Exclusive to in the UK restocked 2nd week of November.

Ranked top by Migro in his 'What is the best LED grow light on the market for small grow tents 2021?' 

The Atreum Hydra -100W Full Spectrum LED Grow Light is perfect for up to 60 x 60cm (2 x 2ft) grow areas. With proprietary, algorithmically spaced LEDs, the Hydra - 1000 has a lower central hotspot than other board style LED Grow Lights and provides an excellently even and uniform spread over small footprints.

Unique Dimmer with Digital Display

Atreum Lighting uses the latest LEDs for a high fixture efficiency of 2.7umol/J, delivering powerful light output. This can be dimmed with exact wattage being seen and set from this beautifully designed, unique controller with OLED display.

Uniform Photon Distribution

The Atreum Hydra-1000 is the only plug & play board on the UK market to feature LEDs algorithmically spaced to produce the most uniform PAR map for its class in the industry. This means your canopy will grow more evenly than similar LED boards on the market.

Full spectrum, Full lifecycle

This grow light can be used for all stages of a plants growth cycle, from seedling through to flowering. The dimmable light with an actual wattage draw display is the only one of its kind that ensures you know exactly how much energy you're drawing.

Remotely Mounted MeanWell Driver

The driver and controller can be set up off the light, and outside the tent to reduce heat and so as one lowers and raises the grow light, they can consistently reach for the same place to adjust the light whether that be in or outside a grow tent. The Hydra 1000 uses MeanWell XLG-100-H-AB drivers.

Plug & Play

The HYDRA 1000 comes ready to use out of the box, no wiring or set up needed.
