Bring on the rain

We have our first rain barrel up and ready to catch some rain!  We are suppose to get some rain this weekend (but we were suppose to last weekend and didn't).  Right now we have the gutter on the backside of the greenhouse.  We  hope to install one on the front as well.  Our goal is to have this barrel able to water the raised beds inside the greenhouse.  This would free us up from using so much of our water.  Our water here is not cheap so anything we can do to help we will do it!  I will be doing a rain dance just so I can see it all work!  Ha!
