Combating High Produce Costs

My strategy for dealing with the high price of produce is to try growing some things myself. At home I was able to grow tomatoes and sometimes lettuce in pots on my deck.

On my balcony I am attempting to grow broccoli, lettuce, and sweet peas. In just 4 days two out of the three have sprouted, sticking the pots in the refrigerator for 2 days seams to have accelerated the germination process.
I'm still searching for a plant nursery were I can potentially find s potted citrus tree or grape vine to further enhance my balcony garden.

Happy Birthday Dad!
