Metro Manila, Philippines: Like any major city in south east Asia, Metro Manila is concrete laden, very hot and not really conducive to growing anything. A year ago, I built a traditional NFT hydroponic system. It worked for a while but a lot of things went wrong. Aside from the cost and the effort put into the construction, the PVC pipe I used to distribute the nutrients deformed due to the heat. Eventually rats took it as their new home then their new fridge! It was a major frustration.
Not this time. After watching the TED talk, I immediately constructed my first window-farm inspired hydroponic system. And IT WORKED! I’m now growing Kangkong in my six level vertical farm! I’m so happy. And I spent only $3.62 (PHP155.00) on the whole thing!
