I know this has been said so many times before, but I guess I'm a geek and STILL get excited!
I did the math this evening out of curiosity-- just by growing and harvesting my own lettuce for feeding myself (and my guinea pig) - using salads for a meal (lunch of dinner) two to three times a week- I haven't been able to pick anything else yet- my grocery bill has gone down from $80-100 a week to $50-60 a week. What a difference in my bank account and otherwise!
Not only that, but I never realized how much different something fresh grown tastes vs what I get in the grocery store! I can't wait to see how my cherry tomatoes taste.
Now, if only i can get my roommate to try some of the fresh garden greens, he refuses to even try a leaf. "I'm sure it tastes just like lettuce" as he eats a salad out of a bag! augh!
