Building towers of recycled bottles and/or pots offers fantastic opportunities to grow fresh food with a minimum of water and fertilizer.  One can grow at home, in cities and villages, all kinds of vegetables and herbs.  Bottle towers are a wonderful tool to alleviate hunger and malnutrition.  They can be built at the lowest cost by any family everywhere on earth, particularly in drylands and deserts.
<p>Can you put more than one plant in each bottle, also can you use smaller bottles say 20 oz size?</p>
<p>In bigger bottles several plants can be grown. In smaller bottles (20 oz) only one.</p>
I absolutely love this, thank you
Thanks a lot !
