You said... "UV bulbs are ordinary full spectrum bulbs that prolong the spectrum a bit further than violet so they behave exactly light ordinary ones when it comes to plants"



The spectrum of the UV bulbs is not the only problem for plants. The main problem is the intensity of the light. UV bulbs generally have low intensities of light in the visible spectrum, and this is why they fail to help plants to grow.

Also, they are more geared toward the blue spectrum and the growth of some plants is impaired due to the lack of light in the red spectrum.



I've found that ordinary compact flourescents (for normal household use) that can be bought with much higher visible light intensity, and with a warmer spectrum, seem to provide plants with more of the light they need (and they don't affect the heat/UVB gradient of the cage adversely).
