I use two Reptisun 5.0 48" tubes and a polished nickel reflector. The uv-b works fantastic. I have several dozen plants in a garden - four Bubbleicious are right under the uv-b tubes. Everything about the plants is better: they are STINKY - they smell like Bazooka bubblegum!! and STICKY, the plants appear to be fantastically healthy in every way, the stalks are thick, the buds are thick, the each plant feels like it is heavy with oil in the stalk ... even way down low under the canopy, the sucker buds are HUGE too.
In tha same garden, I have some (pricey) Dinafem plants - they are great plants but those Bubbleicious under the uv-b are MUCH better.
I can't believe that I [in italics] am growing this fine weed.
