Re: LED lighting Any idea if anyone has experimented with using heliostats and light pipes (fiber optics) to move sunlight from the outside to the inside for growing plants, while eliminating the heat issue - for growing plants? I know it has been done for lighting a room, as well as for artistic purposes - but I am not sure about whether it has been tried for indoor farming...?
