At Lowes as well as my local hardware store (McLendon's), they are selling Ez-Drain, a french drain system that basically seems like styrofoam peanuts surrounding a corrugated plastic drainage pipe encased in mesh sock. It's then buried under the soil - no need for gravel. My questions are:

Anyone have any experience with this or recommend this?
Also, seems like a simple concept - can I simply make this myself rather than buying it retail? (i.e. just buy some peanuts and use some landscape fabric as a sock around a corrugated pipe?)
