How to regrow green onions - not.

Google "How to regrow green onions", or "re-grow green onions", and you will get hundreds of testimonials on how well it works. This would be great if it actually produced a healthy crop but plants need minerals and micro-nutrients to actually be nutritious. 
Yes.  You can re-sprout onions in water, but the problem with re-growing green onions from scraps is that they really don't last forever if you simply put them in water alone. Eventually they stop growing, because even hardy plants like green onions need nutrients from the soil or other source.  The bulb, or whatever you are using, will totally run out of building block materials to grow.  The nutritional value and taste will wear out too.  Sun and water isn't enough, nor is internet hype.
