Abstract
The present invention relates to a gelatinous moisturizing substrate for controllably delivering water and oxygen to the root zone of growing plants with micro nutrients, auxins, preservatives and surfactants added comprising a mixture, by percent weight, 97.6% water, 2.0% carboxy methol cellulose, 0.15% aluminum sulfate, 0.04% sodium benzoate, 0.04% potassium sorbate, 0.0167% zinc sulfate (22.23% zinc), 0.07% acetic acid (99%.0 pure) and 0.005% sodium sesquacarbonate. The composition maintains substrates viscosity. As a result, the moisturizing agent releases water, oxygen and the added nutrients, preservatives and surfactant into the root zone of the growing plant at a controlled rate.
