I have done several things that did not work like my mind thought it would, to many to mention. On those misters I put mine 10 foot apart, that way they overlap some, I have 65# of water pressure so you may have to experiment a little to get the right distance. Also make your main water line is 3/4 and reduce it 1/2 where you come up for the misters so you will have enough volume. I used 3/4 x 1/2 tees so all the upright pipe is 1/2 inch. I attached mine to the box itself. My boxes are 3 foot apart so one set of misters will do two boxes.
