Try setting the air pump on something hard and heavy like a flat brick....or srew it down to a thick piece of hard wood...It might quiet the pump down some...Okay so my commercial air pump sounds like my fucking compressor at work (huge sigh). So Im going to try and make a double box for it and insulate the inside with acoustic ceiling tile or studio foam (if I can find/afford it) to try and tone this thing down. Ive got time for one last grow this year, its gunna be a x2 5gal dwc single screen (24"x50" w/2"x2" spacing) grow. Im pretty sure Im going to use my pineapple express fems.... if not Ill try the blue cheese. My grape soda is looking HOT OFF THE BLOCK. Shes still got very dense nugs that are starting to turn amber pistils and are showing obvious resin production. The buds are beginning to grow in size, however I dont fore-see them getting taller than 3-4 inches. Pics to follow.
Ya I see Vumar....Well the problem isnt vibration. Its the shear noise of the compression. I was gunna make a 8"x10" box at 7" high and just insulate it with foam then drop it over the pump. Maybe leave some slots for fresh air intake... and it'll be right next to my fan that blows over my ballast to cool it... so temps wont be an issue. I just have to muffle the noise, the vibration I can deal with.
