Google STRUCTURED WATER. Use it. Structured RO is what my indoor garden gets.
I have a simple water structuring setup my dad built for the garden out of a 5 gallon bucket, a couple funnels and two smaller buckets. It has a sub pump that pumps RO to the top funnel where it spins a clockwise vortex, then into a hose to reverse the spin for a counter clockwise vortex in a second funnel, then back into the 5 gal which acts as the 'res' and holds the pump. This simple device will do about 4 gallons at a time.
A 2008 documentary titled 'water' is where he got his idea, and internet research of course. I makes sense to me after hearing what the chinese researcher found doing side by side tests with structured vs regular irrigation water as the only variable changed. The structured water crops required 20% less water, yielded more weight, more nutrition, and had better growth rates and general health. BAM!!!
Basically water has memory based on its supra-molecular structuring, and 90 degree bends and filtering technology like RO destroy the structure (human pipes have LOTS of these) to a point where the water is in a sad state for interactions with biology. It can be structured again by simply flowing in vortexes and other natural bends and also by other means like "love and gratitude" amazing simple nature tech. A small amount of fully structured water can structure large amounts of regular water. Enjoy everybody!
I will get pics of the unit and better citations for structured water when I am back home. Love and Gratitude for everyones input on natural gardening on here and for showing the way to the cootz thread!!!
