I'm now really curious what happens here.


The UV gave the right lettuce the deep red or purple colours. This fella was growing, washing, packaging into clam shells for Wendy's fast food salads. They wanted that dark colour for their salad mix. The LED over HPSodium gave a 90% increase in germination and 10X less power consumption. We ended up with UV lights in T5's. Basically a T5 with out much phosphorus in it to colour up the lettuce.

I am not sure if it was the UV or the infrared. Infrared is really bad for our eyes as well as UV.
