Re: Painting inside of hoods

Using aluminium foil instead of painting is effective, but I went to a 
hydroponics shop and bought a reflective mylar film - around 95 % 
reflectance - that's much better, almost like a mirror.  I got enough for 
two 3 foot hoods for about $6.00 australian. It's very thin and flexible, 
very easy to work with, and seems more effective than the aluminium foil 
it replaced.
