I looked but didn't find much info on this. Does anyone have experience with using a plexiglass heat shield between their light and the plants?

If so...

The section of my closet in question is about 3 feet by 3 by 9 tall. At the top is a large carbon scrubber, and air is pumped in from two places; one at about 2 feet from the floor and one at about 4 feet. This section of the closet is fairly tightly sealed.

1) How much space (gap) should I leave between the edge of the plex and the closet wall, if any?

2) How many inches should there be between the plants and the plex, and the light and the plex?

3) How much would this cut down on the light from my 600 watt HPS, or is there a special "very clear" plexiglass that I should use?

4) What thickness should I use? I imagine that 1/4 inch should be plenty.

5) Should I drill any holes in the plex, or leave the two compartments mostly air-tight.

6) What are CO2 considerations for this? I have the stuff and intend to install it after a harvest fairly soon.

Thank You.
