The Hortitek Growsaber Ultra 20watt is a versatile and energy-efficient light bar tailored for all stages of indoor plant growth. With a tunable spectrum from 3000K to 6500K, you can optimise light for propagation, vegetative growth, or flowering, all from a single fixture.
It delivers a maximum PPF of 33µmol/s while drawing just 20 W, offering excellent light output per watt.
Control is simple a wireless remote lets you adjust both spectrum (12 colour steps) and intensity (12 dimming levels). The durable aluminium housing is IP65-rated, making it splash and dust resistant, and its low-heat operation ensures safe use near delicate plants.
