Totally helps. I'm going to thin the bedding out after school today. I started covering the sides with tinfoil last night but ran out of tape and only got half done. It's already helping a lot. My temps this morning are:

90 beneath the sub, directly on glass. (Too high?)

55% humidity

73 for ambient. So it's getting up there!! I need to finish with the tinfoil and see where that leaves me. Much better than 65 lol
