Can't comment on frogs/salamanders.
However most plants will not like a UGF
at all. the plate can interfere with rooting, and if it doesn't the plants will root thru it. Thus every time you replant, you destroy the roots, and every year when you have to pull the UGF
to clean the plate, you destroy the roots.
50/50 lighting is not for plants. is it 50 UV
, or 50 Actinic...because I've never seen a daylight/UV
bulb, but I've also never looked for one, so it could be a normal reptile bulb for all I know.
but 50/50 daylight/actinic isn't for plants. you want 100% daylight. Without it, you have .5wpg and will have a hard time keeping java ferns growing, let alone any more light intensive species.
