This is, as some have mentioned, right out of a Hovind seminar. Am surprised you didn't include the giant tomato tree story as well. What Hovind claims is that the pre-flood world had a layer of water suspended in the sky that blocked uv radiation but allowed useful wavelengths of light through. This had the effect of making the Earth a perfect greenhouse where plants and animals grew larger and lived longer. Great hypothesis with just one little flaw..... is completely untrue.
Water does not block UV very well at all. In fact, light in the UV spectrum travels farthest through water. Long wavelengths of light, the ones green plants require, are blocked by water. If this magic water canopy existed, it would actually have made plant life impossible. This principle is called light attenuation and is why aquatic algae has evolved multiple photosynthetic pigments. Green algaes are restricted to shallow water as the red/yellow spectrum of light is absorbed very quickly. Red algaes, Rhodophyta, utilize visible blue/violet light and can live deeper (deepest living photosynthetic organisms that rely on sunlight are red algaes).
Of course facts never deterred Hovind before, when he needs to make point he will bend scientific principles at will to fit.
