I don't think the thickness of the glass would cause any problem since 
the energy loss within the glass itself is pretty negligible compared to
the loss due to the scattering (unless you build a "hood" with relector
to cover the light). The optic engineer in this mailing list might be able 
to confirm this. We know who he is :) .

Another problem that would occur is that most plants grow towards the direction
where the light comes from. Therefore, you would end up with plants growing 
sideways.
