Hi dale,

I was going to ask you why but found an adequate google answer. Here are some interesting uses for HP that I found:

# Some horticulturalists and users of hydroponics advocate the use of weak hydrogen peroxide solution ("Spanish water") in watering solutions. Its spontaneous decomposition releases oxygen that enhances a plant's root development and helps to treat root rot (cellular root death due to lack of oxygen) and a variety of other pests. [19][20] There is some peer-reviewed academic research to back up some of the claims.[21]

# Laboratory tests conducted by fish culturalists in recent years have demonstrated that common household hydrogen peroxide can be used safely to provide oxygen for small fish.[22][23] Hydrogen peroxide releases oxygen by decomposition when it is exposed to catalysts such as manganese dioxide.

# Mixed with baking soda and a small amount of hand soap, hydrogen peroxide is effective at removing skunk odor. [24]

# If a dog has swallowed a harmful substance (e.g. rat poison, chocolate), small amounts of hydrogen peroxide can be given to induce vomiting. [25]

# Hydrogen peroxide is used with phenyl oxalate ester and an appropriate dye in glow sticks as an oxidizing agent. It reacts with the ester to form an unstable CO2 dimer which excites the dye to an excited state; the dye emits a photon (light) when it spontaneously relaxes back to the ground state.

Similar to Ferti-gate systems. A closable entry point into your mainline with a small hose attachment sucking hydrogen solution from a bucket container(might be difficult to get a certain controllable concentration at the plant). Like the hose-end sprayers used to fertilize your lawn(this might give more control over concentration).

The hard part is to establish the concentration level of the hydrogen peroxide solution being sucked up into the water hose stream. I guess trial and error using ever increasing concentration of HP until there is plant damage. What do experts recommend as far as the solution concentration for plant roots? JMHO and just pour on the right concentration on the soil below the plant from a watering can or aerate your soil and drain or irrigate less. Aloha
