I'm getting ready to build my new plant shelf and wondering what would be the best thing to use for a reflective covering?
I've looked at Mylar which is mirror finish foil like stuff and then something called "Panda Film" which is waterproof, bright white inside and light blocking black outside. Panda Film can be cut for vent/air intake holes and have a zipper or Velcro access added so it can be made into an actual "light confining tent".
And then there's the stuff I was originally going to use which is a metallic foil laid over bubble wrap and called "reflective insulation" which might maintain altered temps better than the other two.
So, what do you guys use for reflectivity? Which of these three might you choose if you had the choice to make? At the moment I'm leaning to the 6 mil panda film but have any of you used it?
