Re: Cement Bricks @ Home Depot

Thanks Scott.  I live in the L.A. Basin.  Here the water is always hard
and alkaline. So me, my plants and I are used to that.   I just wasn't
sure if cement bricks might leach something toxic.  I guess the colored
cement bricks would NOT be safe to use.

Looks like it's time to experiment...
