On the 3rd floor on my house in Marikina City I have grown, Potatoes, Carrots, Onions,
Pumpkin (nearly took over the whole area) and tomatoes. All were grown in bags. Not grow bags but the much bigger specialised bags. Everything was OK but I need to water/Shade/tend everyday , which is OK for me as I love to grow.
It can be done even in Manila, as steve says you might be very suprised.
