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...
