canopy lining

[tgriffin]

Does anyone see a benefit of lining a canopy with a reflective material such as the one in the link below?

If you don't have individual reflectors it might be of some benefit, but even then it would be of limited benefit and likely do more to increase heat than anything else.

HEAT!!!! That is something I want to try to do everything to avoid! BTW.. I'll be using a single 400watt Radium in a Lumenmax Elite. Thanks for the reply

+1 on the heat issue!

Check out aluminized mylar film. Google link below:

It's typically 95-98% reflective. Mylar is just a trade name for polyester or the technical name of polyethylene terephthalate. As such it has some sensitivity to heat, so I would not put it near a MH lamp. You might use a bat-wing reflector next to the lamp and line the rest of the hood with this stuff. Test it before you walk away and leave it running, and use fans to remove heat from an enclosed hood type design. This is used a lot in indoor growing/greenhouse set ups.

FWIW-

Melting point is 254 deg C, or 489.2 deg F

So, it has to get pretty hot to melt, but will begin to curl/shrivel way before that. See link for more info.

What about heat inside the tank? Would that be affected?

No more than with any other reflector.
