Carpet/Blanket question

So my growroom has a slide door that has tons of light shining through. I put up a blanket in front of it to sheild light and to insulate the RH a little bit. It's a wool blanket and I am wondering if this will cause problems for my plants if theres any dander or anything on it. Also, my growroom is carpeted. Is this gonna cost me?

Makes it easy for bugs to find a hideout.

You know those cheap vinyl tablecloths with the padding on one side?

Get 2 white or light-colored ones, lay them together so the felt sides are touching, and make a hem out of duct tape.

Voila, an instant, insulated curtain for your slider.

aha good idea. thanks alot!
