Tomatos and blumat

I'm working with 20 or so varieties of tomatoes this year, nothing major I know but I just received my blumat stuff the other day and was wondering if anyone here has experience using this system on tomatoes specifically. I'm really going to make more of an effort to get the water as close to ideal as I can this season.

I had to look up what blumat is. Seems like a passive irrigation system that uses ceramic "carrots" to dispense water individually to plants, I do like the concept. It does seem quite pricey though in relation to cost per plant to irrigate them in a market gardening context, compared to the pricing of a standard drip irrigation with a heavy mulching to reduce the amount of water needed. On a home scale though this blumat style of irrigation hooked into a rainwater system seems like a cozy idea.
