this idea would work for bigger plants and would gather light from farther.
but yeah thanks guys
ok I also have another topic from another post to address..........
this is about foil and hot spots
if little bends in foil could create hot spots they wouldnt be able to travel out that far in the first place and heres why.......
did you ever burn ants with a magnifying glass???? there is a spot where the light is the smallest dot that gets hot, now when you bring the glass farther away it gets cooler and cooler. a tiny little wrinkle in foil couldn't focus the light out past the width of the wrinkle itself. sure there will be brighter spots from the bigger bends in the foil but nothing hot enough. same as mylar reflections just less powerfull. I always see plenty of hot spots off mylar. I will also do a pic of mylar vs foil. also I will test if light from a 1000 watt hps could be intensified using a magnifying glass. I bet it wont be anywhere near as hot as sunlight.
