I'm just a sod buster, Brother, I love the feel and smell and taste of soil.
I'm sure you'll get answers here, but I'd spend some time in the hydro section before you drop a single dime.
There's nothing like the smell of fresh fertile clean soil...
In the late spring driving thru the Cumberland Gap in MD omg... The smell of the sweet soil after its been tilled... Amazing.. Just don't drive thru after they fertilize it! Hahaha
