Most hobbies are expensive. And right now, my adventure into farming is still at the hobby level. After growing a few boxes of tomatoes, and a lot of soggy lettuce, I was wondering if I should just give up on the AeroGarden. One consistent finding in the “Hydroponics Experiment” is that it’s simply cheaper to buy veggies at Costco or the local grocery store. I like the idea of growing my own food. But if this is going to work, I really have to cut costs.
