Reflector Question

Ok so I had to rig a Super cheapo reflector out of one of those lasagna aluminum throw away baking pans cause I am out of $ for now.

It is set up with a 250W HPS. My question is, would the shiny aluminum be best or should I spray paint the inside of it flat white?

And would the white paint stand up to the heat of the 250 W bulb being right up against it?

It should work. If you paint it, I recommend one that's an elastomeric type paint. There's a lot of paint out there that can withstand heat. Elastomeric type paint can withstand a pretty good amount of heat, since it is mostly used for roofs.

If you actually take the time to research aluminum foil products, you will quickly learn about its true reflectivity. Aluminum foil is a great reflective surface, and has a better overall lifespan than spray paint (especially when applied to a metal surface). Though it is true that aluminum foil is also great at reflecting infrared radiation (heat), meaning that your grow room will, on average, have a higher temperature. I would recommend sticking with the baking pan for the time being, until you are able to purchase a reflector.
