Totally making one of Sandra's drippers. I've never given it much thought since I've always used a mister. The only thing I thought of before this (other than buying a 15 dollar bucket from petco?) was poking a hole in a water bottle. Sandra's idea looks cheap, easy, and efficient. I think I might add a cover to the top of the water to push down onto the water thus giving it the force it needs to push the water up the hose line. I want to put my dripper on a shelf I just put up about a foot below the top of the cage. This ought to the make it easy to shelf and drip. Especially with an adjustable valve. Also, I suppose it'll help keep debris out.
