I had thought that would be a great idea too. I was talking to a few people who experimented with it and they seemed to not have been too satisfied with the results.
Maybe it depends on how long the drought lasts for?
It would only be good for a bad drought or a lawn with no sprinkler system.. Since we got alot of rain, most yards are all greened up now..But now Im leaning towards the organic system swstout is doing..
