Just thinking out loud, but "if" the TH lilies raised water temp, wouldn't it be a boon for northern pond owners? Increased fish metabolism, longer lasting holes in the ice, higher catch rate by targeting the lilies? I would think it all depends on how deep the water is below any potential heat generating material.
By golly you may be on to something, when we start growing some 12lb LMB here in the colder climates with artificial lily pads you all are gonna start believing!
As for the op, what if these lily pads had a layer of insulation on the bottom side? with a darker color tho, I wouldn't want a white underside tho, is that what they have?
