If you have any small outdoor space that gets 5 or more hours of sunlight per day (a fire escape, a window sill, a front stoop), it’s easy to get started with nanofarming.
1. On a 2-liter soda bottle, drill or punch small holes in the top, and 2” from the bottom. Cut a larger hole in the top. Cut the top off the bottle as shown.
2. Wrap a small piece of metal screen over the bottle top and secure with a rubber band, then turn over the cut-off top and stick it into the bottle. This creates a water reservoir, and the screen will act as a wick to draw the water up from the reservoir.
3. Find a piece of plastic pipe or hose. Stick it through the hole you cut in the top. You’ll fill the reservoir through this hole.
4. Fill the bottle with soil, or soil mixed with compost, down to the metal screen, water the earth well, and plant a seed. Refill the water reservoir every few days or when the soil gets dry.
If you start greens, beans, radishes or broccoli now, you should be able to harvest them before the weather gets too cold.
