Howdy,
Skip the Habba-Mist unit.
Buy the:
http://www.pro-products.com/promistproducts.html
From the Site:
"The Pro MistTM PM-60 micro fine misting system includes an electronic plug in wall timer with memory backup, transformer, Pro MistTM model PMP-60 low voltage pump, 25 feet of suction/nozzle supply tubing, 2 Pro MistTM model PM-MNH micro fine misting nozzles and all hardware necessary to complete your custom installation."
"(PM-60) ProMistTM PM-60 micro fine misting system without reservoir. $179.95 "
Mister Moisture Pro might also be a choice. Skip the non-pro unit. There may be reliability issues with the smaller Mr. Moisture pump.
I'm using a Pro Mist supplied pump and happy with it.
I burned-out several of the Mr. Moisture pumps that were made by FloJet.
