It was about 2" and the gravel cap was an inch. Newbie mistake, but this is how I learn apparently. Ha!
I've heard of people using both, and having success with both. I think its just a matter of how much you use, what kind you use, and how you mineralize the soil. These are the factors (I am starting to understand) that can make or break your success with soil.
