Is the center pane made of glass or acrylic

It’s polycarbonate, wife didn’t want the extra humidity in the living room. Lol

Oh I’m totally on her side, especially at this time of the year when my windows look like we live in a rain forest. I’ve been playing with glass and clear plastic over mesh lids too. I was surprised to see that the glass resulted in a 5% or so loss of par, even with condensation, but the clear plastic (I think mine was acrylic, not polycarbonate) made a MAJOR dent in the par readings. And idea is polycarbonate is more par-friendly?

It wasn’t horrible. If I remember correctly when borrowed the club meter it was maybe a 10-15% loss. That is a broad guess. This omg acro was happily growing under my ai hydra at around 60% output.

this was 3-4 months earlier, same piece.

Polycarbonate must be much better. I think I read as much somewhere. I am currently losing about half of the par from my light due to acrylic (based on the par meter).
