I have been using full spectrum 6,500k tubes now for a full five months.
I can issue this report if it helps anyone in their considerations.
I am running ten tubes right now in five fixtures. Electrical cost increase for me is a bit less then $10 a month.
I have African violets placed at the ends of the tubes. They are now producing their second sets of flowers since they went under the tubes.
I am not a succulent expert. But I am trying a few under these tubes. Three of the eight have now developed flower spikes. I love jades and a seedling jade is growing like crazy!
As far as my orchids go, I have had 9 Paphiopedilums develope bloom spikes under the tubes. Four Cattleyas have produced spikes recently and I have had a few Latouria Dendrobiums bloom. Now two of those are spiking again, 3-4 months after blooming this fall.
