Dave - its tough to go wrong with IWTC, because the directions are good, its preinnoculated, and it is a good product. I use it sometimes because its conveinient, and you can buy 1/2 acre bags from most sporting goods stores for around $30.00. You do not need a large plot, 1/2 acre might do you well (1 acre is better, long and skinny, with a "fat section" is best).

Good luck, let us know how you make out.
