A no-fuss recycled windowsill herb garden. Self-watering planters like these aren’t a new idea. This version looks nice & works great for small herbs and plants. Empty beer bottles or make a larger garden with wine bottles.
In addition to recycling plastic bottles and jugs for watering slowly, try to recycle your waste water for the garden. Water collected in rain barrels, or water from the bath or laundry can be used in the garden. I'd probably use glass bottles.
Mine should be up and running soon! Got an apartment with limited space? A Hydroponic window farm is for you. All you need are plastic bottles with cuts in them, plants, soil, and some supports to hold it to a PVC frame.
