Connecting communities through growing food arts science & a vegetable. THANK POTATO features an unique contemporary potato grow show, art & science exhibition. Urban Farm‘s THANK POTATO potato collection is grown in up-cycled water cooler bottles and artificial grass off cuts, utilising waste stream materials to house and grow our potato plants. There are 180 different varieties of heritage and heirloom potatoes in the collection. Why grow Potatoes as an urban food project ? The potato is the fourth most important food in the world. But so far, it has not featured prominently in the debate on food security. The potato crop is of key importance in that it provides high nutrition and is an adaptive species for climate change. Potatoes use less water per nutritional output than all other major food sources.
