Well, I just bought a HPS/MH light and ballast to drive up the light levels higher than my t5HOs and LEDs put out, as well as the needed warmth from the lamps for these dens. Just hooked it up today, I have my arranges iuteoalba, my tobaense, my Fredclarkeara, and my dend smilliae under the new fixture, but off to the sides so as to not exceed their cultural-specific recommended light FCs so we will see how they do.
