So I have 6 5 gallon buckets filled up with wonderful ladies. I upgraded to a bigger air pump a few weeks ago when the 70 LPM gave up. I now have one of the big 110 LPM commercial pumps and it runs at about 45 to 50 db. The challenge is I have the grow room on the 2nd floor of an apartment. The buckets seems to echo vibrations through the floor so downstairs there is a very significant hummmm. Much louder than in the room next to the pump. I have tracked this down and its the buckets for sure. I have tried raising the air stones (2x2 inch cylinder stones)so they are not touching the bottom of the buckets. helped a bit but not enough. then I bought the rubber floor mats that you put in a kids room so they don't get hurt. the 1 foot squares that lock together like a puzzel. Stacked them so there are 4 under each bucket (4 inches of soft rubber). Helped a little but still loud as hell down stairs. I even went to a 45 LPM pump but the sound only dropped a bit, still to darn loud. So my question. How bad would it be if I were to run the pumps on a timer. Something like 10 minutes on then 50 off around the clock. Would this be ok? or am I going to see problems? I just started the timer tonight and figured I would ask while I let it run tonight. Really hope this is ok, I can deal with 10 min of racket every hour but a constant hum won't cut it. Are there any other suggestions for reducing the sound I have not thought of yet? thanks in advance for any help you can offer.
