Plant lights do make a difference. I can't use LED due to Lyme light sensitivities. I have lots of good windows but I have continued to use the light in the bedroom for the ginger. Eventually all the kitchen plants ended up there. The poinsettia in particular loves the plant light. Mine's just a good quality T5 light.
They totally make a difference!
These are LED-one fell last night so I'm going to have to come up with a new way to hang them.
