I would hook it up drip style with the soaker or emmitter in line hoses... I think holes in PVC might be very unexact in their water delivery

I would be concerned that much more water would come out of the holes nearer the hose than the far end.

i agree too a ddrip system would be easier especially with a timer for early am waterings,so things would be dried off to control fungus problems.

I guess we'll see. This will have a timer on it like it would with a soaker hose. The Drip systems seemed expensive and a big deal to set up but I can always go back to it.

There is a poor man's solution--poke tiny holes in a plastic soft drink bottle and fill it with water and set in as needed to effectively water each square. A bit labor intensive but it works--and it is recycling.

I'm with vatikan111, but I'm trying clay instead of plastic. Traditionally, ollas are unglazed clay pots that you bury in the ground near the roots of your plants. You fill the pots with water as needed - once or twice a week - and they seep water through the clay walls into the soil as the soil dries. I put a link to a more thorough explanation and demonstration. Instead of buying them premade, I made several ollas from sets of two 6" terracotta pots that I siliconed together: caulked up the hole in the bottom of a pot, put a bead of caulk around the rim of the pot, and put a second upside-down pot on top so that the rims of the two pots joined together with the caulk, making a diamond-shaped olla. I left the second pot's hole open so I could fill it with water. Total cost was about $25 for 10 ollas.
This is my first year trying them so I can't be sure about the results. I'd love to know if anyone else has used them. I have 10 ollas for a 4'x10' raised bed, each hold not quite 2 gallons of water.
