I've never attempted to set up irrigation before. After looking at a few different systems, I decided to use Power Loc parts and 1/2" poly tubing. We drew a scale diagram of our garden, including where the plants would be and how the irrigation would be configured. This made it SO easy to figure out how many and what shape parts we needed. This system, combined with an awesome timer (Claber Aquauno WOT471) allowed us to enjoy our summer and garden with no worries about watering!
