People are growing food in recycled plastic bottles in windows in big cities all across the world with Windowfarms, a vertical hydroponic garden system. Herbs, lettuces, leafy greens, strawberries, peas and even squash are suited to this method which works year round and of course requires no soil.
The best part about this movement is: there is an ongoing mass online collaboration to improve the system, so it gets more efficient all the time, the more users that participate. It's always evolving.
Right now, this may seem like a fun way to have some veggies in an apartment window. But imagine if this is just the beginning of a new way to grow organic food on a larger scale- anywhere, anytime?
People helping people grow food in windows, without soil: VERY Nextworld!
