PAR spectrum lighting is easily proven and quantifiable, directly affecting photosynthesis and allowing a plant to grow. Less obvious is the impact that spectrums of light outside the PAR range can and do have on your plants. Whilst not directly contributing to photosynthesis, they impact plant morphology and overall genetic expression. The new 60W UVA/UVB LED supplemental bars allow the grower to tweak the spectrum to encourage the best out of their plants. Used independently or attached to an existing DAYLIGHT LED fixture, full customisation of light has never been so easy.
