Hello all. I see tons of these small clip-on solar powered fans on auction sites like ebay. I grow in a tent. I understand these would not be sufficient for moving large volumes of air, I have proper blowers for that already, however, would these be good for clipping on sides of tent and using as an oscillating fan blowing into the foliage? I like the idea of having less power cords to deal with in the growing area, and the fact of them running off of light energy. Anyone have any experience or input? Thanks for reading.
