Quiet Your Grow Room — Kill Fan Noise for Good

That constant whooshing, drumming, or rumbling from your inline fans and ducting runs? It doesn't have to be there. Flexible duct silencers absorb and dampen airflow noise at the source — whether it's on a straight run, around a bend, at your exhaust, or at your inlet. Stack a few in the right spots and your grow room goes from loud to near-silent.
